Surly wants you to be able to set up you ride just the way you want it. This pair of adapter washers make it so you can throw your favorite 135, 170, or 190mm O.L.D. 10mm solid axle hub into the rear end of a 142, 177, or 197mm spaced thru-axle frame. Add the adapters, add the wheel, install and tighten the nuts and, bam, you're ready to rip. Make sure the solid axle on your wheel is the right length for the frame spacing. For instance: 190mm OLD QR goes with 197mm thru-axle spacing.

The tool-free Maxle Ultimate Front brings exceptional stiffness and durability to your ride in a high clamping force, easiest-to-use internal cam thru-axle system.

Problem Solvers' 11-speed Freehub Spacer converts your 11-speed freehub body to accept a 10-speed casssette. Use this spacer if you are running a 10-speed drivetrain on a new set of wheels with a 11-speed freehub body. The spacer is 1.85mmm thick.

RockShox's Maxle Lite is a lightweight aluminum through-axle system. It lets you remove and install your wheel as fast as with a standard quick-release while delivering the awesome stiffness with the improved strength and control of a through-axle. Plus, the lever can be closed in whatever position you like and no tools are required for installation and use!

The Problem Solvers Handlebar Clamp Shim allows you to fit almost any handlebars in almost any stem. It's machined of light and durable aluminum and grooved on the inside to hold tightly.

The Problem Solvers SpaceOuts Set includes 2 5mm hex bolts and spacers that let you add space between your bottle cage and frame. This comes in handy on frames with clamp-on front derailleurs and tight clearance for cage mounting.

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.

Wheels Manufacturing hangers are stiffer than almost any OEM hanger, which improves durability and shifting performance. - OEM hangers are only produced by a handful of manufacturers, mostly in Taiwan and China. As a result, you will see many bikes with exactly the same hanger. Bicycle manufacturers may make mid year changes. Please use the hanger photos to select the proper hanger for your application. - These hangers DO NOT INCLUDE attachment hardware with the exception of QBP # FS1561 (DROPOUT 399) - CNC machined 6061 aluminum - Made in the USA
