Chainset /cassette combination question
Can someone tell me best combination of gearing for hills ,mostly long drag hills I struggle on ,my average speed on flat is about 22 mph,my winter bike is 50/34 with 11/32 cassette,new bike has 50/34 with 12 /29 ,if I change chainset to 53/39 with 12/29 cassette what difference will this make ,

Agreed - anyone that can average 22 mph on the flat on his own is a pretty decent cyclist which makes his question a little puzzling. Unless he is an 18 stone powerhouse TT rider........
