Does anyone know of a source of a suitable replacement for the o ring on an early shimano qr seatpost clamp. From the bits I have it appears to be 21x24x4.5 but this size or anything near does not exist.
My Inbred has been built as a 69er before, it was great and I would do it again if only I could get 26 and 29 gravel tyres in the same width, 26 gravel kings are only in 2.1" and 700c 38mm
Recently built an old inbred frame in to a gravel-ish bike, on-one steel forks, tiagra brifters and crank, xt 9s rear mech and shimano cable disc brakes, tyres are panaracer gravel kings 2.1". It is quite honestly the smoothest bike I have ridden, looks like a dog dinner but I dont care.
The Shimano road cable callipers are great, I have them on one bike matched to some old sora 9s brifters with standard housing and really cant fault them in anyway so much better than the shitty old tektro IO ones they replaced.
