How does my bike fit change over time?

I am probably going to be on my present ride one more season. I’ve never been professionally fit on it. I feel comfortable on it but am tempted to get fit from a good fitter. If I plan to buy a new bike in a year from now is that a good idea or should I wait? Will my current bike fit numbers work in a year from now? I guess my real question is: what factors influence my bike fit? Fitness? Flexibility? Will it change much in a year?

OK, should’ve known better than to post this on a Friday night. Maybe I’ll bump it on Monday. Back to the aero helmet, aero fork, Cervelo, ceramic bearing, Hed vs. Zipp threads…

I’m not a pro, but I’d say body comp is the biggest reason people can’t ride in their optimal position.

Things like flexibility and neck strength will come pretty quickly.

Just pick your best position and stick to it.
