Wanted or SWAP: Strong 27.2mm x 400mm seatpost w/layback

[wynne]

I have a 2010 Race Face diabolus seatpost 27.2mm x 350mm which is just about 10mm too short for my requirements. It's in excellent condition and looks like new. Can do pics later. Comes with box and instructions.

I need a 400mm long post with layback and height markings as described above, preferably balck. Doesn't have to be in mint condition as long as it's strong and not too marked. Happy to swap or buy or just sell the Diabolus for £25 posted.

Thanks

Rich
