This trainer is the most convienint smart trainer that we have ever seen CPT Cycling coached riders use, becuase there is no need to take wheels off to use this trainer.
This eliminates almost all of the usual cross combatability issues seen with direct drive trainers for axles or cassettes. The Rollr has a generous 4.8 KJ flywheel,
compareable to many mid range direct drive trainers for effective similar workload to power, compareable to the road.
