The weather was overcast yesterday, but it wasn’t raining, so there was no excuse to get out and pedal around a bit. Chris called me just as I was getting the bike ready to roll, but there was still a lot of daylight left after our lengthy discussion of matters tactical. This was a good opportunity to evaluate the performance of the Conti Rubber Queens that I had just switched to. On the first outing at the Ditch, they felt slower, but this was offset by the better traction and ride. On the pavement, I could definitely feel the increase in rolling resistance from the size, weight, pattern, and compound differences between these and the Michelins they replaced. Climbing was hellaciously sluggish. At speed, they tended to want to stay in motion, but accelerating them up to speed was harder. Once at speed, there was a more noticeable gyroscopic effect in turns, where they resisted the steer into hard corners. There may also have been a little change in steering feel from the slight geometry change the larger diameter imparted, but I really doubt I can feel something that slight. They are still new with molding hairs all over, so I’ll give them more time to settle in before I make any judgments. Heck, from the computer data, they were faster than my last ride on Michelins!
