The Decathlon D900 smart trainer is a high-end trainer from Decathlon that boasts some serious spec at a laughably low cost. It uses a 5.2kg flywheel to generate electromagnetic resistance of up to 2000 watts and can simulate up to a 20% incline virtually. It has a claimed accuracy of +/-2%, meaning that at 200 watts it should read between 196 and 204 watts.
It comes fitted with a Shimano road 8/9/10/11/12 speed compatible freehub, while a SRAM XDR hub can be purchased separately. It also features adaptors for QR 130-135 x 5 mm and Thru Axle 142-148 x 12 mm, but states that it is not compatible with the Cervelo P5 or the Cube Attain.
