As background I am not a full time fitter but rather do as a hobby - i have attended FIST courses and average about 30 to 40 fits per year over the last 4 odd years primarily on Tri bikes. I have a client with an 2014 Cervelo R5 and a 2009 Cervelo Soloist - the r5 being slacker and taller than the S1. My question to the more experienced on the board is can a case to be made for different fit co ordinates for the cyclist for these bikes?
