I have seen a great seatpost online that i would like to fit to my brompton. The only trouble is that the OD is 31.6mm instead of 31.8mm.
The Brompton seat mechanism uses a plastic shim to help the seatpost rise and lower smoothly.
Anyone know the dimension of the brompton seattube and if it is possible to buy a new shim and fit to brompton frame so that I can fit this seatpost properly?
thanks!
