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.

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.

Well, there are myriad applications: tandems, cyclocross bikes, fixies, tricycles, recumbents, cycles for those with special needs, bike polo bicycles, those 4-person bikes you see on beach boulevards, and so on. You could even link both models of Cable Doublers together for the ultimate in redundancy!

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.
