WhisperDRIVE Freehub body XD Driver 11Spd MTB


The JetBlack WhisperDrive is the first direct-drive indoor trainer compatible with 12x142mm thru-axle bikes.

Direct drive, of course, means your bike connects directly to the trainer, rather than your rear wheel turning a roller. The WhisperDrive is sold with a SRAM/Shimano 10/11x Freehub Body. If you have an 11-speed mountain bike with SRAM groupset and want to train on the WhisperDRIVE indoor trainer you’ll need to purchase the specific JBT-75C XD Driver Freehub Body.
