I'd say that 1:30 would for sure work. However, I might have yet another obligation that day, so let me get back to you later today/tonight. Oh, and I just got my SLR saddle...gotta test that out.
By the way, the ride yesterday was awesome. We did a touch more than 40 miles, and the off-road section was sweet. Nothing like running through a set of sandy whoops (at least half a mile of them!) on slick road tires at speed. Got a little loose there, but man, that was fun.
