    single speed kit that is nice looking with a couple of cogs and all you need for converting your rear wheel to single speed. the cogs are tought but a bit weighty.

    I have ordered from Planet X a number of times now and the service is always great, texts when bits are dispatched and arrive, and always quick despatch times.

    Looks well made and easy to fit to bike. I have not managed to connect the chain yet as I snapped a tendon in my finger removing the cassette from the rear wheel! I am sure it will work fine.
