The Fly Tractor TT Sprocket is a refined version of the original Tractor Sprocket, that's been refined with the help of Ruben, Sergio & Larry's input. Fully CNC machined from 6061 T-6 aluminium with a 6mm thickness gives the Tractor TT Sprocket all the strength, rigidity & durability it needs. Adapters for 19mm, 22mm & 24mm spindles are included so you can run the Tractor TT on all cranks. section Product Specs TYPE:
