I had to go one size bigger on my tire size from stock because I was getting pinch flats on a regular basis. I figure too much weight concentrated over the rear tire, that is the one that kept blowing. I don't know what size they are because I am at work. They are slicks. Down from the stock 85 psi to 65 psi. No flats since I put them on. Spoke count is whatever comes from the factory stock. Can't go fast if you keep getting flats so I had to put on tires that would last.
Blazing Saddles, what is the total ascent on your 30 mile ride and tell me where you got that info because I know the Garmin Training Center, Bikeroutetoaster, and Motionbased, all give different info on the same route. I am curious to compare it with my ride to see if what I consider hilly is really hilly? Your speeds are incredible!
