I've been having a blast on my new Giro 20, I really do enjoy riding it. However, I'm a bit frustrated with my speed for I feel like slug on this bike. On my DF my average speed ranges from 15.0 - 16.0 mph. When I ride the Giro on the same routes that I take my DF my speed drops to a very slow and depressing range of 13.0 - 13.4 mph. I feel very comfortable on my Giro, have the seat reclined back though I'm still trying to dial the seat in (the inside of my left knee is sore and has been talking to me the past two rides on the Giro). I'm splitting my time between my DF and the Giro simply because I enjoy both and don't want the DF to gather dust or feel neglectedHow long did it take you gals to increase your speed on a consistant basis?
