Subject: RE: Fred D Mentor Group - Part IIKathyG - 2012-08-23 9:48 AM I had my 7th bike fit yesterday.... Really happy to see you back in the saddle I had a bike fit this week. My 3rd. It was on a new bike. I told him that previously I was comfortable, felt somewhat aero and felt I could generate good power. I spent the whole winter dialing in the position But rather than just mimic my previous position we agreed to start from scratch and then compare the two fits. All my angles/measurements were pretty close except he had my seat a little further back, ie rotated counter clockwise around the BB, which means a little higher in front. He also had my elbows wider. I went to the Formula 1 track which is a great aero test road and sure enough I was about 2km/h slower on a bike that should be faster.. Felt comfortable, powerful, but I was slower. So I went back, and switch my position to what it used to be and saw an improvement this morning. I need to do it again. It was windy today so it doesn't lend to accurate results. But taking the wind into account it looks good. This is the third a fitter has put me into a comfortable, powerful position but at the expense of aero. We focus a lot on fit and position for the sake of comfort and power but I wonder how many fitters truly look at aero. I suggest people with powermeters learn to use Golden Cheetah and Chung analysis for getting a feel for their aeroness. I think people are leaving a lot of free speed on the table. |
