I built up my Centurion SS about a month ago and have only been using it on the 3 mile commute to work since then. Our club did a fast paced training ride today getting ready for a local race. I decided to push my luck and use the SS for the ride. I put on a set of my old MTB pedals and hit the road. We did a 15 mile out and back and I hit the turnaround point about 45 seconds back from the lead pack that I normally ride with riding by myself. It was more downhill coming back so they put a bit more of a gap into it but I was surprised how well I did. We then picked up the wives and did a 15 mile social ride on the same route. I loved it! I'm really starting to think about the fixed stuff next. This is FUN! I'm beginning to like this stuff!!!
