Comes with 11 speed Shimano cassette and skewer (set up for standard rim brake road bike). Does all the erg mode stuff you want for Trainer Road, Zwift etc. Drive belt has recently been replaced.
It functions fine, but full disclosure - I got a new one because my other half said it was getting too noisy. But if you live in a place with no downstairs neighbours and a nice isolated room, I'll let it go for a meagre asking price. Happy to let buyer test first.
