Coach to help select/fit new bike?
Me - 50 year-old male, Denver area, reasonably fit and working on getting fitter. Currently riding Scattante R670 - I like it, but I'd like to do some longer/mountain rides this summer and would like a better bike for those rides.
I'm thinking of finding a coach to help me select and fit my new bike - an expert on what's available and preferably someone unaffiliated with any specific shop or manufacturer. The number of different manufacturers and models is overwhelming, and once I'm on the new bike, I want to be sure that when something starts hurting it's not because the bike doesn't fit right.
Is this a reasonable plan? Any recommendations (either for or against specific coaches)?
Thanks for your help.
