I purchased this a few years ago, but only used it for about 100km and it's been stored in a closet since then. There are some scratches from when I moved. Compatible with both 135mm quick release and 142mm thru-axle. Includes an 11s cassette sprocket. This is a direct drive, high-precision trainer with a built-in power meter, perfect for training. - Model Name: Direto XR - Included: Instruction manual, power adapter, adapters, trainer unit - Features: Direct drive, built-in power meter - Color: Gray - Compatibility: Road bikes Thank you for looking.
