Quick answer
A smart trainer fits your bike when it supports your rear axle (130/135 mm quick-release or 12×142 / 12×148 mm thru-axle) and has a freehub body for your cassette (Shimano/SRAM HG, SRAM XD/XDR, Shimano Micro Spline or Campagnolo). Of 30 trainers in our database, every current direct-drive model covers the common road and MTB axles out of the box; the variable is the freehub body, which you swap for SRAM or Campagnolo drivetrains.
How trainer compatibility works
Three things decide whether a trainer fits — and what, if anything, you need to buy.

Frequently asked questions
Almost — but two things must match: the rear axle (the trainer must support your 130/135 mm quick-release or 12×142 / 12×148 mm thru-axle) and the freehub body your cassette mounts on (Shimano/SRAM HG, SRAM XD/XDR, Shimano Micro Spline or Campagnolo). Direct-drive trainers ship with an HG freehub and adapters for the common axles; you swap the freehub body for SRAM XD or Campagnolo drivetrains.
