Currently i'm looking at getting a MTB power meter,i currently have Powertap Pro+ for the road bike which i get on fine with.( apart from the rubbish bearings they come with)

I have been looking at the Sram Quarq ones, as i would much prefer a crank based unit, so i can race with it and not worry about wheel weight if i had a MTB Powertap.

Found the odd one on ebay, but it seems the Quarq ones are based around BB30 (not sure if they do other sizes) and my frame is bb92 *takes your normal Hollowtech 2 cranks. (24mm) i think.

the cheaper the better really, just wondering what people would advise?
