I am going to try to make both, but "she who must be obeyed" might not be back in time for a 4:30 today. Sandpine I started at a 34 X 16, then X 18, and now at 20T. I am looking to upgrade my cranks and will probably go to a 32T up front. I have a tough time with a lot of the climbs at Alafia with my current set up. Do you feel like your spinning out too much with the 32 X 20? What is the pace like Friday? (Distance?) I still don't have a lot of endurance, don't want to hold people up, but tired of riding alone.
