Bike Fitting Question

Is there a difference between F.I.S.T and Serotta Professional Bike Fitting sessions? If so, which one is best?

I am new to a TriBike and I have an opportunity to get a FIST fit from the dealer and/or Serotta fit from another company.

Any comments would be appreciated. Thank you.

I would not characterize either as “best” or even one as better than the other.

I would suggest that both will produce very good results in getting your fit and position optimized and either is significantly better than no systematic approach to fitting.
