I try and keep in stock all sizes between 25.0mm and 27.4mm in 0.2mm increments plus a few of the larger oversize seatposts.

The important length dimension is rails to limit marks – different manufacturers have different ideas on how much needs to be inserted into a frame. If the length is specially critical please ask me to double check as the measurements given are approx – normally should be within ± 5mm. If there is no limit mark I have assumed to leave 60mm in the frame.

Please check the seatpost size you need carefully – its very common for frames to have been fitted with seatposts smaller than they should have. This results in the seat lug ears being squashed and the seat tube is then put under extra stress often resulting in cracks starting from the base of the slit. Seatposts should be a tight sliding fit.

I cannot accept returns where new seatposts have been fitted and marked.

PLEASE LOOK at the large version of the pictures – that will give you the best idea of condition.
