I recently had the fit with Sacha. This was not my first bike fit and I must say
I was impressed with his approach. Although his Speedvagesns are race oriented, he makes a scope of bikes under the Vanilla label that are anything but race bikes. My impression is that once in a position (where he spent a lot of effort to get me comfortable with good form), the position was tweaked further to get virtually all the weight off the hands to support the position). I can't tell you if his theory is right for me or the population in general, but in no way did I feel it is brand image related. We talked about theory of bike fit by Hogg and Bontrager who are not really concerned with KOPs, but more about getting weight off the hands once a position is found.
I don't know if he is right for everybody or anybody, but I think he is pretty genuine and wants people to love riding his bikes.
