I have had one since raceface had them in stock a few months back.
i found it works best with a short cage clutch or type 2 mech as well
i have seen a few people running them on bikes using regular mechs too.
you can use any cassette 6,7,8,9,10,11 speed ect
any mech will work. (though a cluch or type 2 works better)
any chain will work too.
