Folks, I think i may know the answer to this but can someone confirm for me . . . .
Probably three times in the last few years, I have ascended Honister, Newland and Whinlatter passes in one ride (ie, steep!).
The first twice i got up all the above relatively easy, on an old ish alloy bike, with a front 38 tooth chainring and a 26 tooth rear.
Yesterday, i tried the same hills on a new carbon bike with a 34 chainring and a 32 rear sprocket. I struggled like hell. Ouch indeed !!
Given that both the above ratios give about 28" (looking at gear tables/charts), can I presume that yesterdays struggle was due to the newer bike having less efficient hill climbing (front to back) gearing and my skinny legs simply couldnt push those gears (even on a far lighter bike) ???
Thanks all
