Unfortunately, he has only ridden the bike about 4 miles since Christmas Day. We've got a bit of a cold spell going on where we live. Over the weekend the temps didn't rise above 32 degrees. Unable to get out with him during the week due to work (new job/no vacation time earned) and short amount of daylight hours. Planning long rides Fri. - Sun.
During the short 4 miles on the bike, my son did notice the improved responsiveness of the bike. Probably due to the lighter weight (7 lbs lighter than he first bike - Specialized Allez Sport).
I'm interested in his thoughts on how it corners, descends, climbs, etc. which won't been known until a nice ride. I'll let you know and I plan to test ride it myself. My first concern is dialing it in for him. His first race is two months away.
31 year old son? Hey with your 31 year old income, I could probably pay for your pedals! Ha!
