Sorry for the delay, been a long working week so far. Just had a rummage and I must have sold the eternity post. Heres a few pics of the use sumo post and a couple of stems. Post is 27.2, used and has wear lower down the post, but it's a massive 400mm so will be well hidden by a seat tube. Seat clamp parts are brand new (aside from fitting to a build before I found a carbon version of the same post).
Stems are both 31.8 clamps. I think I have a 25.4 clamp version somewhere, will take a look tomorrow in the light. Both were new before fitting and builds have done less than 50 miles between them.
Apologies for the poor pics, garage is a bit of a mess and hard to get at things quietly at the dead of night.
If interested in anything, let me know and I'll grap some better pics.
I do have a hope stem which is black and 25.4 but on my sons bike. I could swap it out for another stem. Also fitted to my sons bike are some minty use carbon bars in 25.4. Might also have another set of use carbon bars in 31.8 to go with the stems. Need to check. Let me know if anything floats your boat.
If you are after any other brit kit, let me know as I've a few other parts from middleburn, pace, x-lite, hope etc. Might have a spare use carbon pro saddle too (my fave but am trying to thin out the bikes and spares stash down to something more manageable).
