I don't think Robbie has had a chance to ride the Semi-Pro much, if at all. Being the one who sold him the bike, I can say that the bike rides great. I rode it on a couple of metric centuries, iab's Spring Ride, and did numerous club rides on it. I found it to be quick and agile without being twitchy. Robbie helped me ID the bike before I bought it. I had told him that if I sold it, I'd give him first chance. He took it. I love what he has done with it. The changes he made have been all for the better.
