Reg Lizard Posted March 6, 2009 Share A colleague of mine has asked me whether you use to get oval shaped crank blades in the past- apparently it was developed for people with knee problems. He discovered that the blades on a 26 year old bike he recently bought are oval shaped and not round. Any comment or pictures. Link to comment Share on other sites More sharing options...
