How many of us find the gears on our bikes need to get lower as the years get higher ? I put an MTB freewheel on my old road bike 2 yrs ago so my lowest gear is 42x28 . since I broke my hip in a crash I've found that this gear is'nt quite low enough ,when I stand, up a hill it feels like a spike in my hip joint so I realy need to look at going lower still ,a new bike with a triple is out of the question for a while yet (other commitments) so Im thinking of finding a 39 chainring to replace the 42 . I like climbing hills ,I find them a personal challenge but I've noticed I have sub-conciously been avoiding a lot of the hillier loops I used to ride pre-crash! How low can you go?
