I rode my usual 30 miles yesterday and the ride seemed unusually rough. It's a beat up road to begin with but I was just getting rattled and fatigued, so I thought I was just tired. The next day I took the SS off the rack for a change of pace and for some reason, I decided to check the pressure coming off the scuba tank I use to inflate tires. 150 psi! O-k-a-a-a-y. Krylion carbons ride like Flintstone wheels at 150 in case anyone is interested.
