BTW i should have mentioned that i want shorter cranks partly because i have knee issues. i've read more than once that cranks too long can exacerbate knee issues, particularly anterior ones.
still happy for any help and specific recommendations!
cheers, m
Let us know what your actual inseam is, crotch to floor standing is socks and we can give you a better opinion on what a good crank length for you is rather than guessing. Nominally I would say that 2.5mm isn't going to make that much difference and I would be going down to at least 170mm but then again if your only around 5' 6" or less then even shorter cranks may be in order.
