Offering a variety of hand positions for comfort over the long haul, it also features 30mm of rise for a more upright and relaxed riding position. With a clean aesthetic, it’s a great option for taller riders looking for more rise and for bikes with a low-cut steer tube. - Lightweight, aluminum construction - Available in various widths - 31.8mm clamp diameter

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.

Surly's Open Bar Handlebar is the go-to option for a good time. It features lots of space for grips, shifters, brake levers, or any combination of the a fore mentioned.

It's at home on bike paths or neighborhood cruises, and at an ominous 666mm, it's even wide enough to tackle some singletrack.

Track stars and fixed-gear converts will love Surly's Ultra New Front Hub. This gorgeous hunk of aluminum sports sealed bearings for all-weather reliability and low friction. And, the hollow axle is forged from flex-free chromoly for steering precision, long-lasting durability and simple quick-release compatibility.

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.

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.

This is our Excellent Adventure Thru-Axle. It upgrades your bike's rear end for hauling cargo trailers, should you feel like taking Rufus along on your errands. Extensive product testing with our Bill and Ted Trailers provided an "awesome experience," but time travel remains a risky endeavor. Designed for use with slotted horizontal or vertical single-position dropouts, the Excellent Adventure Axle is compatible only with 12 x 148mm hubs. Compatible Surly models include Skid Loader, our compact electric cargo bike, as well as Karate Monkey, Krampus, Grappler, Ogre, Lowside, ECR, and Troll. Once again, the 12 x 148mm hub requirement cannot be overstated. Visit your local Surly dealer to discuss other scenarios you may have in mind. - 12 x 148mm hub compatibility only - Designed for use only with Surly's Bill and Ted Trailers - Works with slotted horizontal or vertical single-position dropouts

Hurdy Gurdy is another nifty device that keeps a rear wheel from slipping forward in the dropout under pedal load. It's designed for the Cross-Check's semi-horizontal front-loading dropouts, and will also work on many other similar dropouts. Hurdy Gurdy is investment cast of stainless steel for durability and good looks, and shares many of Tuggnut's design features. Its two axle holes allow for a wide variety of fore/aft wheel positions, it will work with standard QRs, bolted axles, and nutted axles up to 10mm.

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.

Surly's MWOD Inner Chainrings are made from stainless steel for extreme durability. These rings are compatible with Surly's MWOD cranks.

Like some of Surly's other chain tensioning devices, Snuggnut keeps your rear wheel from slipping forward in the dropout under the pedal load of your powerful gams. It's specifically designed for bikes that feature 12mm horizontal, vertical-slotted dropouts and is particularly suited for singlespeed application. Snuggnut is CNC-machined for durability and good looks, and shares many design features found on Tuggnut and Hurdy Gurdy. Note: The Snuggnut is compatible with horizontal thru-axle dropouts only.

Rated fully KICKASS by a very authoritative entity who will remain unnamed, Surly's cast and polished stainless steel clamps won't rust or chip paint because they can't (even the black ones!). They're shiny! They look good! And most importantly, they deliver the clampability seatposts crave.

Whether for derailleur clamp clearance, tire clearance, or personal preference, sometimes it can be advantageous to run the wheel further back in the dropouts. Monkey Nuts install into Surly horizontal dropouts to make spacing the wheel back easy. There are 3 different sets depending on the type of dropout and axle configuration the dropout is intended for. Simply select the correct version of Monkey Nut, install it into the frame, and slam the wheel all the way forward. Bang, done.

Surly Monkey Nuts v3 Dropout Spacers let you keep that rear wheel nice 'n' perpendicular in those horizontal dropouts, no matter how much of a diesel you are. So go ahead, stomp on the pedals and let the rooster tails fly. They're sold individually because most folks only need one on the drive side.
