To use SRAM’s 11 speed cassette you’ll need the XD driver hub for your wheels. I think Easton do one, but you have to do a bit of searching online.This replaces your old hub so you can have 11 gears 10-42. You’ll then need the 11speed shifter and rear derailleur too. It does get quite expensive, so a cheaper alternative is to have a 1×10 set up which there are many to be found. You’ll still use your original hub, derailleur and shirter, and just change to a single front ring from Race Face or Hope for example. At the back you can use a set up like one up components sell. search for them online and you’ll see. 🙂
