I was deciding between a Rans V2 and a TourEasy . Does the lower bottom bracket of the Tour Easy put less strain on the knees. Does the higher bottom bracket of the Rans V2 give a better leverage for speed. There are even higher bottom brackets on bikes from Bacheeta like the Strata. Following the same reasoning I guess the people that ride these very high BB end up needing knee surgery. What is the streight and skinny on this . --Keith--
