Critique my Fit

May 5, 20 14:47

Greetings ST. My old bike (now designated trainer bike) was a 2012 Cervelo P2. I got a Retul fit from a LBS before I learned about the F.I.S.T. method. Leading up to Ironman Arizona 2019 I dealt with a bit of ITBS when running, but never felt discomfort on bike. When I got my new QR PRFour, I did my best to recreate my fit specs from the data I was provided. I had many many good and relatively comfortable training rides in the lead up to race day. During the race, however, I began feeling discomfort from the ITBS early in the bike. By the end of the bike, it was full-blown pain, which made the run delightful.

Could this have been due to my sub-optimal fit job, or was it my dumb luck that it chose that particular bike ride to flare up?

Any input is greatly appreciated.

Any change to pedal system or cleats when you went to the new bike (I'm guessing "no")?

Not enough info, but I'm doubting it was fit related. Lots of things come into play in a race, and the thing with ITBS is that it's "self energizing" (it rubs and gets inflamed...which makes it rub more....which leads to more inflammation...) so some small tweak might have set it off.

You're right. Pedals and cleats remained the same.

there is no way to know anything based on that picture other than your bike might be too small for you.

Very doubtful that it was dumb luck. How long were your training rides leading up?

Seat too high or at too steep an incline can often cause it. Could also be from cleats being too close together or any number of other issues

Yes, if you want real answers you'll have to provide more data. There is a good thread about how to take a proper fit video and it should be used as a reference point.

By too small I really mean you will run out of length, horizontally, is what I am guessing. But it's impossible to say based on a static photo like yours.

Here is my version of that photo (you also can't really tell anything about my fit based on this one photo)
