I`m part way though the mock up stage on my Dawes Kingpin build,
And was wondering what length cranks the R20 builders among us use??
My Kingpin is fitted with 406 rims with Schwalbe Duranga 20" x1.1 tyres
and i have a set of 2 piece Tiagra 170mm with 34/50 cranks to go on,
Will i need to shorten these cranks??
