Bkool?s 12-mm Thru-axle is a sophisticated accessory that lets cyclists use Bkool trainers with bicycles that have a 12-mm thru-axle system on the rear wheel.This accessory has been designed to fit perfectly in the arms on the Bkool trainer (Bkool Pro and Bkool One), turning it into the perfect solution for using the trainer with this type of bicycle.If the bicycle has the standard 5-mm axle system, simply use the skewer included in the Bkool trainer box. If, however, the bicycle has a 12-mm system, the Bkool?s 12-mm thru-axle will be needed.Bkool offers three different models for this accessory. The proper axle to use depends entirely on the brand and model of your bicycle.142x12x1 Tapered (Syntace X-12) - Specialized - Epic, FSR, Rumor, Stumpjumper, Diverge (Road), Crux142x12x1 Tapered (Syntace X-12) - Felt - Nine 1 (2016), Nine 2 (2016)142x12x1 Tapered (Syntace X-12) - BMC - Team Elite 01, Team Elite 02142x12x1 Tapered (Syntace X-12) - Cube - Access, Elite C68 Race, Team Elite 02, Reaction GTC SL (2016), SLT 2X, Stereo, Attain Pro (Road)142x12x1 Flat (DT Swiss) - Scott - Spark 910, Scale 910142x12x1 Flat (DT Swiss) - Cube - Reaction GTCSLT (2016). 142.12.1.75 - Trek - SF9, SF8, SF7, Superfly 9.8, Suplerfly 9.7, Superfly 9.7.
