Agree there. I'm sure you need time and miles to adjust to the new bike and gearing - 60km round the Trossachs would be a good start ....magnatom said:On the last CC ride (see the elevation) I only found on one occasion that I really wanted another gear. Really ? I'd have thought you'd have been fine. I was pretty OK (I'm on 52/42 and 14-28) and I'm not as young (and fit) as you are. However, I can imagine on longer hills I might just need that 25. I'm just not quite sure if I need to spend money on a new cassette or not. I probably need a few more 'longer' rides to be sure.
