Repurposing A Seatpost Shim

ProsDoes the job for me.
I have a Tortec Explorer seatpost rack. It works perfectly on my old mountain bike with its massive 31.6mm seatpost but recently I bought a 31-year-old Bickerton, on which I want to occasionally fit a rack. The Bickerton has a 25.4mm seatpost and the rack's Q/R clamp won't go that small. This shim (the largest o/d I could find in silver to match the seatpost) solves the problem perfectly. Slide the shim onto the seatpost, slide the seatpost into the seat tube, clamp the rack to the shim, job's a good 'un.

Will this work with a Brompton Telescope Seatpost?
By

Can I put the 26.6 version of this shim in the top of the lower part of a Brompton Telescopic seatpost an then mount a (suspended) 25.4 seatpost instead of the original upper part of the seatpost?

Thanks
Johannes
Hi there,

Yes you can, or you can use SJS Cycles part number : 46149 with a 27.2mm upper.

Thanks

Hi,

The internal diameter of this shim is 25.4, the external diameter is available in lots of different sizes including the 27.8 size you are after. Just select the correct size from the dropdown menu.

Thanks.
