One of the coolest things about Surly is if they can't find an existing part that fits their standards, they just make one themselves. This cable hanger is made to fit around the oversize bolt on their Constrictor seatpost clamp so you can be sure it will fit around almost any other seatpost clamp bolt too. It comes complete with an adjusting barrel.

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.

Profile Design's aero-bar extensions are made of light and durable 6061 aluminum, come in different bends to suit all riding positions and feature the standard 22.2mm diameter to fit Profile and other brand base bars and extension mounts (base bars and mounts sold separately).

The Wolf Tooth ReMote is a significant lever upgrade for cable-actuated dropper seatposts.

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. If using 10/12 Adapter Washers and QR wheels use a Tuggnut instead. Snuggnut is not for use with MDS Chips. Compatible models listed below: - Wednesday - ECR 29+ - ECR 27.5+ - Ogre - Krampus - Karate Monkey SS - Karate Monkey 27.5

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.

Shimano's In-Line Brake Cable Adjuster with quick release allows you to make changes to your road caliper brake's cable tension or open a brake caliper's arms to remove a wheel.
