The adapter replaces the freehub with a fully locked fixed gear hub to fully replicate the track bike experience indoors. A special set of dropout adapters reduce the axle width from 130mm down to 120mm. A few extra chain links added to the chain will be required. We recommend having a second chain with a quick link that is longer for use on the KICKR
