Thanks for the info and ideas!

1. I run 23c tires, but have been interested in trying 25c (at least on the back). I am 150lbs and run 90/100psi front/rear

2. I have about a 7cm seat to bar drop at the moment but am going to drop the bars a bit more and do some fit checks to see about my seat setback, ability to balance with hands off bars (per John Cobb and Steve Hogg strategies).

3. I have taken a few single weeks off at a time during the season, but now am in the middle of a two week hiatus that includes a lot of not sitting in an office chair and a lot of icing of the ischia when sitting. Once I get back from this business trip, I may ride one day this weekend for 30-40 miles, but will wait on any more riding till I see the body muscle dynamics expert this coming monday.

I think going to a 25c rear tire is probably a good idea.
