Dubbed 'Straggle-Check' frame bags, these bags are designed to fit both 700c and 650b Straggler and 700c Cross Check frames. Size up one size on your bag if you've got a 650b Straggler frame and voila, it fits. These are handmade by Revelate Designs in the U.S., made of Dimension Polyant VX 21 polyurethane coated fabric. It's durable, rip resistant, tightly woven and laminated to make it highly water resistant but not fully waterproof…. Revelate advises using stuff sacks inside (such as the one in which our bags are packaged) if you risk riding in extended downpours or underwater. Surly's Straggle-Check frame bags (as well as their mountain bags) are now using a ladder strap system, which allows greater flexibility in how you attach the bag to your frame. The ladder straps let you customize the fit and placement of the mounting straps so if you have some weird contraption clamped to your frame tubes like a chain keeper, cable pulley, or some trinket grandma gave you, it won't interfere with the mounting straps on the frame bag. They're also including foam bumpers for the mounting straps to minimize thread abrasion to the bag and attachment points Quality YKK brand water resistant zippers – with an improved, water resistant zipper 'garage' – control compartment access and help keep the weather out. Zippers are sewn with a stretch panel to relieve stress on the zipper as well. Stress even kills zippers. The large main compartment has a flexible divider inside, and there's a hydration port to make sure your whistle stays wet. There's also a compartment suitable for smaller items you'll access relatively often, like your map, phone, hard boiled eggs, uncontained pudding, marbles for playing marbles, your dugout, that ring you found that makes you disappear when you put it on, or whathaveyou. Frame bags such as this are light and reasonably voluminous. They are stable because they center weight low between your wheels and body, and they go places where racks and panniers are often troublesome, like singletrack. Note: due to the rough texture of the mounting straps, prolonged use may lead to scratched or worn paint. If you're worried about keeping everything looking pristine you probably ought to look for some other type of bag, or figure a way to protect the paint, such as duct tape, or tatting a top tube doily - for example.

Our Wednesday Fork is made of the same 4130 Chromoly steel as its frame counterpart. It's ready for trail use and features butted and tapered blades with thru-axle dropouts spaced at 150mm. It features many accessory barnacles (or braze-ons, if you prefer to speak in "official" terms) like barrel bosses at the dropouts and crown, mid-blade thru-blade eyelets and Three-Pack Mounts on both fork legs. Specifications: - Axle-to-crown: 468mm - Offset: 47mm - Steerer: 260mm, 1-1/8" straight - Tire Clearance: 26" x 5.25" - Weight: 1262g - Brake Mount: IS Disc Brake 160 - SHIS Crown Race Diameter: 30 - Front Axle Type: 15mm Thru x 150 mm - Front Thru Axle Diameter: 15mm - Front Hub Spacing (mm): 150 - S.H.I.S.

Surly mountain frame bags are designed specifically to fit in the main triangle of your Surly frame. Their mountain bags are now using a ladder strap system, which allows greater flexibility in how you attach the bag to your frame. The ladder straps let you customize the fit and placement of the mounting straps so if you have some weird contraption clamped to your frame tubes like a chain keeper, cable pulley or some trinket grandma gave you, you know it won't interfere with the mounting straps on the frame bag. Handmade by Revelate Designs in the U.S., these things are made of Dimension Polyant VX 42, a synthetic sailcloth. This stuff is durable, rip resistant, and tightly woven and laminated to make it highly water resistant (but not fully waterproof… Revelate advises using drybags inside if you risk riding in extended downpours or underwater). Compartment access is controlled by quality YKK brand water resistant zippers. The large main compartment has a flexible divider inside, and there's a hidden pocket too. There's also a compartment suitable for smaller items you''ll access relatively often, like your map, phone, hard boiled eggs, uncontained pudding, marbles for playing marbles, your dugout, that ring you found that makes you disappear when you put it on, or whathaveyou. Frame bags such as this are becoming more and more popular. They're light, reasonably voluminous, stable because they center weight low between your wheels and body, and they go places where racks and panniers are often troublesome, like singletrack. Surly offers them in ten sizes for many of their off-road frames. Buy the bag that matches the size of your frame based on the handy sizing chart. Note: due to the rough texture of the mounting straps, prolonged use may lead to scratched or worn paint. Those worried about keeping their frame looking pristine should immediately look for some other type of bag, or figure a way to protect their paint, such as duct tape. Or tatting a top tube doily. For example.

Like its QR cousin, the Disc Trucker Thru-Axle Fork is designed to mount racks and fenders and haul your worldly possessions. It's also got modern touches like dynamo routing, compatibility with flat-mount disc brakes, and three-pack mounts on both fork blades to satisfy your deepest cargo desires. Captured 12mm thru-axles make tool-free removal and installation possible. Offered in 26" and 700c wheel sizes, the Thru-Axle fork clears 26 x 2.1" or 700c x 47mm tires. With a 1-1/8" steerer, it's powder-coated and constructed using the same Chromoly steel as all our other frames and forks. Why? Because we swore a blood oath to steel and we intend to keep it. Note: The Disc Trucker TA Fork is designed to pair best with second-generation Disc Trucker models—those first released in 2020. Defy this guidance at your own peril. 26 Inch - Axle-to-crown: 376mm - Offset: 45mm - Steerer: 42–54cm frames = 300mm, 1-1/8" straight - 56–62cm frames = 400mm, 1-1/8" straight - Tire Clearance: 26 x 2.1" (with or without fenders) 700c - Axle-to-crown: 390mm - Offset: 45mm - Steerer: 56–64cm frames = 350mm, 1-1/8" straight - Tire Clearance: 700c x 47mm (with or without fenders)

The Ice Cream Truck fork is made from 4130 CroMoly steel and is designed for Surly's Ice Cream Truck frame. It's ready for trail use and features butted and tapered blades with thru-axle dropouts spaced at 150mm. It has barrel bosses at the dropouts and crown, mid-blade thru-blade eyelets and triple bottle bosses on both fork legs. That's a lot of bosses. 51mm I.S. mounts use front disc spacing. - Axle-to-crown: 483mm - Offset: 47mm - Steerer: 260mm, 1-1/8-inch straight - Tire Clearance: 26 x 5.25-inch

Designed around Surly's updated Krampus frame (but also employed on the updated Karate Monkey frames as well), this fork has 15mm thru-axle dropouts spaced at 110mm and clearance for up to a 29 x 3.0-inch tire. To accommodate such big tires it's got a longer axle-to-crown measurement than our Ogre or Karate Monkey forks, making it a perfect rigid fork option for lots of 29ers out there. The Krampus fork's blades were designed and manufactured specifically to play well with the unique forces such a long fork with big tires will encounter, and the steer tube is standard 1-1/8-inch threadless. It has line guides for a disc brake line as well as thru-blade eyelets and Three-Pack bosses on both fork legs. - Axle-to-crown: 483mm - Offset: 47mm - Steerer: 260mm - Tire Clearance: 29 x 3.0-inch - Weight: 1180g uncut

This beauty here was designed alongside Surly's Midnight Special frame. In an effort to shed a few grams (it's for a road bike after all), they opted to utilize a unicrown design rather than a lugged one. In addition to the weight savings, it also looks really nice — don't you think? Like the Midnight Special frame, this fork is equipped with modern road standards like flat mount disc brakes and a 12 x 100mm thru-axle. For increased versatility, it has braze-ons for fenders and racks (including mid-blade!). - 100% CroMoly construction, fully brazed crown - Mid-blade thru-blade eyelets - Rack and fender eyelets at the dropout - 12 x 100mm thru-axle - Clearance for 27.5 x 2.32 or 700c x 42mm tires

In addition to the weight savings, it also looks really nice—don't you think? Now, we don't throw the phrase "future-proof" around lightly, so we won't use it here either. What we will say is that, like the Midnight Special Frame, this fork is equipped with modern road standards like flat mount disc brakes and a 100mm x 12mm thru-axle. For increased versatility, it has braze-ons for fenders and racks (including mid-blade!). - Axle-to-crown: 400mm - Steerer: 350mm, 1-1/8" straight - Tire Clearance: 27.5" x 2.32" or 700c x 42mm (27.5 x 1.95" or 700c x 38mm w/fenders) - Weight: 1254g

Once long ago, wool was the material of choice for cycling clothes and other active clothing. In the 80s, synthetics began to replace wool because they were new and shiny and stretchy and you could sublimate flashy, detailed graphics onto them which was a nifty thing for teams and shops. Even while synthetics enjoyed their era of dude-holding-the-bong popularity, however, wool did not die off. It still offered some really great features, like great moisture control and a resistance to putrescent reek. Our jerseys are an excellent example of wool done well. We've tried hard to produce something we hope will become your favorite piece of cycling clothing. Our long sleeve jerseys are made from medium-weight Merino wool. Merino fibers are soft and non-irritating even on sensitive skin. The fabric weight makes them suitable for cool weather to cold weather. They have a high collar to help keep the cold out and the warm in, and feature long body and long sleeves. The sleeves have reinforced thumb holes to help make sure they stay all the way down as you ride. Like our short sleeve jerseys they feature a full length zipper and a reinforced rear pocket with zippered access on both sides.

Surly's burly line of tubular chromoly steel racks have been used on expeditions all over this planet for years.This Surly Rear Disc Rack is made of tubular chromoly steel and is specifically designed to fit frames with seatstay-mounted disc brakes like the Straggler (650B and 700c), Krampus, and Karate Monkey. - Tubular chromoly rack, stainless-steel hardware - Height-adjustable to accommodate 26-29" wheels - Hardware housed in reusable Surly Tool Bag

This expedition-worthy rack is made from 4130 chromoly, so it's tough, light and easily repairable in the field. It's also height-adjustable, so you can get your center of gravity as low as possible for a stable ride. The provided stainless steel hardware enables you to attach your rack to virtually any frame with 26-inch, 700c and 29-inch wheels. And, it hauls up to 80 pounds of gear and is powder-coated to protect it from the elements.

Surly Racks are well-thought-out, durable, expedition-worthy racks that work with most panniers. While their racks aren't limited solely to heavy duty touring, that is what they were designed for. When you're out on the road, the best option is to never ever have anything ever go wrong ever. Right? That's never a guarantee though; so having something that you can repair if it does break can be pretty clutch. Thus, the main bodies of Surly's front and rear racks are made from tubular CroMoly steel with stainless hardware. This means you can probably find someone out there that can torch it back into one piece in the rare instance things go south. The Front Rack is height adjustable and provides either a low or high pannier mounting position, which can be handy depending on terrain. When the ground gets rough, keep your gear high and dry. When the path is smooth and easy, you can load things low and keep everything balanced and stable, with the platform above the wheel providing yet more space for more stuff. It's worth mentioning they've redesigned the Front Rack hardware to be simpler to attach and more compatible with things like disc calipers and fenders. Surly also made attachment plates specifically for their Uni-Crown forks for yet more fork compatibility. This simpler design has fewer moving parts and costs less to manufacture; ergo, costs less for you to purchase. Surly's front rack WILL work with disc brakes on the Troll, Ogre, and Disc Trucker frames. It may take a bit of work to get clearance around the front caliper since the many different calipers out there are many different shapes. The new attachment plates will limit any DIY ingenuity you might need, but if you need to throw a washer or three behind the lower left bolt where the plate attaches to the fork dropout, that's not a big deal. As part of Surly's ongoing effort to make this planet last a little longer, they recently started shipping their racks with a small, reusable Surly Tool Bag that houses the rack struts and hardware. This switch helps eliminate the use of some polybags, thereby minimizing excess waste. Plus, you get a free tool bag out of the deal. Surly Front Rack will haul up to 32kg (70 lb) of well-secured, well-balanced gear over roadways and maintained off-road trails. Front Rack specifications: - Tubing diameter: 10mm - Platform dimensions: 230 x 170mm - Weight: 1382g

Both feature 51mm I.S. disc caliper mounts, brake line guides, accommodations for a rack and fender, and 2 sets of cage mounts (one on each leg) that let you mount large size or standard water bottle cages. Both are designed to run just about any combination of parts and accessories you'd want on a fork and are finished in durable black powdercoat. The only real differences are 1) ECR is disc brake only, and 2) ECR's offset is 47mm, 5mm more than Ogre's. - Axle-to-crown: 468mm - Offset: 47mm - Steerer: 260mm, 1-1/8" straight - Tire Clearance: 29 x 3.0" - Weight: 3.1 lb (1.4kg) uncut

Designed for Surly's Krampus frame, this fork has quick-release dropouts spaced at 100mm and clearance for a 3-inch tire on a 50mm rim. To accommodate such big tires it's got a longer axle-to-crown measurement than the Ogre or Karate Monkey forks, making it a perfect rigid fork option for lots of 29ers out there. The Krampus fork's blades were designed and manufactured specifically to play well with the unique forces such a long fork with big tires will encounter, and the steer tube is standard 1-1/8-inch threadless.

It features a flat crown, drilled to accept a standard-reach caliper brake, and the use of wide 38mm tires. And its stealthy Black powdercoat means your opponents in the Pursuit race will never see you coming!

The Troll Fork is just like the one that comes with the Troll frame, a 26-inch wheeled fully geared utility bruiser and cruiser. Like all Surly's forks, it's constructed of CroMoly steel. It sports removable rim brake pivots as well as a 51mm disc caliper mount.

This beaut here was designed alongside our Midnight Special Frame. In an effort to shed a few grams (it's for a road bike after all), we opted to utilize a unicrown design rather than a lugged one. In addition to the weight savings, it also looks really nice—don't you think? Now, we don't throw the phrase "future-proof" around lightly, so we won't use it here either. What we will say is that, like the Midnight Special Frame, this fork is equipped with modern road standards like flat mount disc brakes and a 100mm x 12mm thru-axle. For increased versatility, it has braze-ons for fenders and racks (including mid-blade!). - Axle-to-crown: 400mm - Steerer: 350mm, 1-1/8" straight - Tire Clearance: 27.5" x 2.32" or 700c x 42mm (27.5 x 1.95" or 700c x 38mm w/fenders) - Weight: 1254g

If variety is the spice of life, then the Moloko bar oozes umami at every bend. It offers a multitude of hand positions to keep you comfortable and in control over the course of a long day riding over varied terrain. It also has plenty of spots to mount your various accessories. Dangle a handlebar bag from it, strap some lights to it, throw a GPS on it (if that's your thing), and ride all day. It comes in a standard width of 735mm but if 685mm is more your style, don't you worry. Surly added cut marks so you can easily make it so. - Material: CroMoly steel - Clamp diameter: 31.8mm - Width: 735mm; Cut marks for 685mm - Rise: 0 - Sweep Angle: 34 degrees - Weight: 709g - Color: E.D. coated Black

I mean it’s that or the old uncomfortable around the waist hug move. You can decide what’s best for you and your passengers.

Our family of Dirt Wizards is highly-focused – one might even say spellbound – on providing traction and control on the kinds of surfaces where nary traction nor control are to be found. Its tread is comprised of a dual row of aggressive, trail-gobbling, beveled knobs in the center and well-spaced, siped knobs to dig into loose corners. Designed to work on 50mm rims, Dirt Wizards are tall and wide, providing next-level traction and cushioning. The casings have been designed to be flexible and responsive, yet durable and supportive.

Who doesn't like t-shirts? Idiots, that's who. What's not to like? You can wear them all the hours of the day. They work equally well in the shower as they do in the pool. They function as both daywear and eveningwear. Surly tripled its functionality by adding a pocket. A POCKET!!! Now they've taken that infinitely versatile garment (it's the Cross Check of Clothes) and had it made out of (what Surly would call our their favorite material) merino wool (after steel and rubber, silly). In short, it's a t-shirt, it's wool, it's got a pocket (A POCKET!!), you wear it. Donzo.

When you're out on a ride the last thing you want is to be limited by your tires in any way. Surly's ExtraTerrestrial tires were designed to let you ride without limits by following a simple tenet for tire design: make 'em high-volume and kick-ass. The ExtraTerrestrial tire was meant to serve as a heavy-duty off road touring tire that shines on hard pack surfaces. It uses a nylon breaker in the sidewalls for cut protection, a molded pattern for anti-cut propagation, and a Kevlar cap under the tread to protect against flats. The ET tire uses a distinctly directional tread pattern and its width yields more traction than you might expect from a tire with such little rolling resistance. The tread is low profile with a file tread in between blocks. The ExtraTerrestrial tire has enough width and traction for the soft stuff and won't bog you down on smooth or hard surfaces. It's made to be durable and versatile and is at home on tour or on the trail. - Bead Seat Diameter: 559mm - Casing: 60tpi, tubeless-ready bead (928g)

An issue many people ran into when they began using 1x setups was chain retention with the front chainring. In the beginning of the 1x movement, many companies dealt with this by using aftermarket chain keepers that somehow bolted to the frame. Many people discovered that using a narrow-wide chainring in conjunction with some type of 'clutch' rear derailleur helped abate or eliminate these chain-jumping issues. Narrow-wide rings use alternating tooth profiles that more positively engage the chain and help control a deflecting chain in bumpy conditions. Your friends at Surly have partnered with SRAM to bring you stainless steel X-Sync chainrings. Stainless Steel is durable. This durability is pretty useful when you're talking about the one ring that is bearing the brunt of all your miles.

In today’s fast-paced world of riseless flat bars and far-too-aggressive-for-our-liking cockpits, Surly harkens back to simpler times. They wanted a handlebar that would suffice for a relaxed cruise to a favorite windowless bar, but would also be suitable should a person decide to take the long way home. The Sunrise Bar is a cruiser bar, a trail bar, and a BMX bar all rolled into one. It has a 22.2mm clamp diameter, but Surly included some Problem Solvers shims so you can mount it up to your fancy 31.8mm stem.

Build your singlespeed or fixie bike around Surly's Ultra New Roadie Rear Hub. This gorgeous hunk of aluminum has the capability you need and reliable sealed bearings, too! It sports threads for a track cog and lockring on one side and a freewheel on the other so you can decide how you want to roll. Plus, this hub's 130mm width fits most road frames and the hollow chromoly axle provides a flex-free ride as well as simple quick release skewer compatibility.

Surly's Dummy Deck provides a light, durable platform for cargo bikes, built to Xtracycle's Longtail standard — including the Big Dummy, of course. The Dummy Deck is stamped from 4mm-thick aluminum, chosen for its strength, durability, and recyclability, and it bolts directly to Surly Dummy Rails to stiffen and stabilize the whole system (it's also compatible with Xtracycle V-racks by using Xtracycle's SuperHooks). It features cut-outs for routing straps and cordage, a mounting hole for a rear light bracket, accessory-mounting holes, and countersunk holes for SuperHook hardware.

Dummy Rails support Dummy Bags on your Big Dummy cargo bike, and Surly's Dummy Deck bolts directly to them, stiffening the whole system for a more stable load. Dummy Rails are made of light, strong aluminum and were designed in conjunction with the Dummy Deck and Dummy Bags; each component works best when used with the others. Like all Surly products, they've built in lots of useful details. For example, the deck-attachment bosses stick up from the rails to create space between the deck and rails, providing windows to route tie-down straps and cordage; and threaded bottle cage bosses located at the rear of each rail provide mounting locations for accessories: bottle cages of course, or lights, cameras, pumps, flags, horns, light saber scabbards, disco balls, spittoons, cornucopias, etc. Dummy Rails will work with cargo frames (including the Surly Big Dummy) built around Xtracycle's longtail standards.

The new chainrings are stainless steel and have improved ramps, gates, and pins for better shifting performance.

Surly's Stainless Steel Chainrings last longer than their aluminum brethern because the 304 grade metal they use is 35% stronger. The rings aren't pinned or ramped so when one side starts to wear you can flip it around and pedal some more! They work great with singlespeed, fixed, and 1x9 applications, and the teeth are 2.1mm thick so they work well with 9-speed chains.

The Surly Truck Stop Handlebar combines the benefits of a drop bar with those of a riser bar.

When you’re out on a ride the last thing you want is to be limited by your tires in any way. Our ExtraTerrestrial Tires were designed to let you ride without limits by simply following the only tenets we have for tire design: they’re high volume and they kick ass. The ExtraTerrestrial tire was meant to serve as a heavy-duty off-road touring tire that shines on hardpack surfaces. It uses a nylon breaker in the sidewalls for cut protection, a molded pattern for anti-cut propagation, and a Kevlar cap under the tread to protect against flats. The ET Tire uses a distinctly directional tread pattern and its width yields more traction than you might expect from a tire with such little rolling resistance. The tread is low profile with a file tread in between tread blocks. The ExtraTerrestrial tire has enough width and traction for the soft stuff and won’t bog you down on smooth or hard surfaces. - Folding bead - Casing: 60 TPI - Recommended rim width: 23 – 30mm

The Knard is a tire that just makes sense. With its tightly-spaced, low-block tread pattern, it provides the perfect ratio of traction and low rolling resistance. It grips well on all sorts of different surfaces and will haul some sausage on hardpack terrain or groomed trails. If you want a tire that has a little less bite and a bit more speed but don’t want to sacrifice traction, look no further. With sizes ranging from a svelte 41mm all the way up to a hefty 4.8”, there’s a Knard to solve all your fast-rolling needs. - Folding bead - Casing: 60 TPI - Max pressure: 75psi - Weight: 510g

The 12mm slotted MDS dropout is the newest chip for Surly's MDS equipped trail frames. You like chips, don't you? The 12mm slotted dropout chip uses a standard derailleur mount for maximum compatibility and is made of cast and machined 6061-T6 aluminum, with a fender eyelet. What's the coolest part about the 12mm slotted MDS chip, you ask? The fact that it also has the capability to run a 12 x 142mm thru-axle in a single speed configuration. This is good news because single speeds are good news. When you get an MDS equipped frame you're getting the option to set it up however you want. You can run a 142 x 12mm thru-axle rear end with a direct mount Shimano hanger, standard 135mm QR or The Mighty Singlespeed. The way this will work is that Surly complete bikes that feature the MDS will ship with whatever chip is compatible with derailleur spec. For instance, the complete Instigator 2.0 ships with the 142 x 12mm thru-axle Shimano chip. If you want to change it to a singlespeed later (and why wouldn't you?), all you have to do is get the SS chip. Frames will ship with all three MDS chips so pick your poison. The 142 x 12mm and 135mm QR chips are made of cast and machined 6061-T6 aluminum and The Mighty Singlespeed chip is 304 stainless steel, because the two words 'aluminum' and 'singlespeed' should never be too close to each other. Bad things can happen…. As you can see, the MDS gives you not just different build options, it lets you use a more varied selection of parts for your frame up builds. The MDS is featured on most of our trail bikes. That's right: Krampus Ops, Karate Monkey Ops, Instigator 2.0 and Ice Cream Truck frames all sport these puppies.

Turn your geared bike into a singlespeed machine with Surly's Singleator. The Singleator mounts to your derailleur hanger and provides a smooth, quiet and adjustable means of tensioning the excess chain slack on any bike. It's made from strong forged steel and features a triple-sealed spring, large-cog capacity, chain guides, fully-adjustable chain line, floating pulley, and a stainless-steel pivot bushing. And, it works with both BMX and standard chains.

Single chainring drive train setups are all the rage these days. With the introduction of exceedingly wide range 10- and 11-speed cassettes, the need for two chainrings has become a thing of the past. But when you only have one chainring, the only thing standing between you and a long walk back to the trailhead is you making sure you don't destroy your one chainring. That's why Surly made a chainring guard to fit O.D. cranks. It is made of aluminum and will take the hit for your chainring. It comes in 5 bolt, 94mm BCD and was designed to protect 22t – 30t rings.

Pair this kit with a cassette cog of your choosing (sold separately) and discover the joy and simplicity of a singlespeed without the cost of a new wheel. The Singlespeed Spacer Kit includes a variety of high quality aluminum spacers so you can dial your chainline and a stainless steel lockring to tighten everything down right.
