By the way, I actually beat my all time fastest commute time today that I had done on my road bike with the Bleriot. Top speed on that route, too. With loaded rear rack bag and tired legs from last weekends big ride.
So I guess it is just as fast as the road bike is, tires and all.
I had been losing pace on bad shifts as I haven't got adjusted to using the compact crankset and bar ends on the bleriot. But today I was feeling like I was actually getting the shifting down good and could keep up the pace. Maybe that had something to do with it.
