System 1 fitting and new found power

I have seen posts about people getting free power from a bike fit. In fact I know someone who got re-fit and got 40 more watts. Someone suggested that they were fitting more upright, thus power at a lower hr but less aero. What can you tell me about system one fitting? I am looking to get an agressive fit on my bike.

WHen I got the bike a felt s32, it was fit but used a 1 inch spacer for the aerobars. I have since gotten rid of them and had to lower the seat angel slightly. I want to put integrated aerobars on it and lower it to a perfect position and get re-fit. I want to do this in the winter. What else would I need other than in aerobars?

I am not quite certain, however measuring wattage via different fittings takes time and several tests. I just recently switched from a System one fit to a more agressive lower and slightly (1cm) more forward position, my back is flat. I did a 54 mile TT on it on the first ride, not pain, felt great. Maybe it took time to get used to a lower position, I dont know.

I got a fitting fom Cobb’s people last spring. They set me up pretty aggressive and foward on my P2k. They did a great job IMO, and it was worth the $. They do more than the SLAM position, in fact, I posted my after-fit pictures here and there wasn’t really any substantial changes suggested indicating that it was very much a FIST like fit. IMO, they have a lot of tools in their fit experience and would probably be very good fitting people who had physical problems.

Like Gary said, don’t expect to see a huge power increase immediately unless you are doing something stupid right now. It takes some time to get used to a new fit.

I must have been tired when I worte that post. I didnt quite articulate it the way I wanted too. lol! I wasn’t looking to get a bunch of new power from the bike fit, although ti would be nice, I was more concerned about hem setting me more upright for more power instead of aero.

Should I be looking for the most aero but still comfortbale that I can get or aero/most power? What about running off a position like a TT position?

I asked them the same question before I went in for my fit. They are not a SLAM only shop. They go with more upright positions only when it is appropriate.

I’m focusing on the 1/2 IM distance right now, I’m relatively young and flexibility is OK and getting better. They have me setup in a FIST like position, 80* seat tube angle and the higher end of Dan’s range on handlebar drop. They went with the higher end of the range to add just a little comfort for the 56 mile ride but I’m stil within Dan’s formula for drop. They said that if I was focusing on oly or sprint they would have dropped me lower. All that said, I’m still riding pretty low and my back is flat and horizontal.

Gary,

So what was the wattage output difference with this lower, more forward position? And same question regarding speed.

Power - no idea, still waiting on my new PT pro, has been 4 WEEKS NOW!!!

As for aeroness (?), my back is now flat, cadence is still at 85-90 and I did a LONG TT on it and, other than my hands falling asleep, it felt great

I imagine it is as powerful a position as I had before, just more streamlined now.
