riccof Posted May 9, 2010 Share When I started cycling many moons back, I had a 105 Biopace crank on my road bike. I recently saw an oval crank (2 blade)on a hard tail and was wondering if any one had any views (personal experience or scientific basis) on merits. Some seem to say it does increase your power, but if that is so then why is this not first choice for any pro or wannabe pro? I look forward to your reply.

Wannabe Posted May 9, 2010 Share Been discussed quite often, one thread was started about it in the last week. Do a search for Q Rings or Roto Rings. Link to comment Share on other sites More sharing options...
