Updated, with some new bits for sale, I'm in Bristol so prices include postage. I'll knock a little off if you're local or buying multiple items:
Alba Optics ANVMA VOG
These are in excellent condition, 10/10. Really good quality, lightweight glasses. Selling these on behalf of my dad who doesn't wear contacts as much as he used to so these have barely been used. The website does a better job of describing these glasses so I've pasted the link below, I think these are a slightly older model.
Zipp Service Course SL stem, 110mm +/-6 degrees
Great condition 9/10. This stem has done a few hundred miles, just the wrong angle. I slipped with my torque wrench and scratched where the stem bolts are, although this is non-drive side so no one will ever see it ;) Fantastic condition otherwise.
Sram X-Sync 48T chainring
Great condition 9/10, around 200 miles of use before swapping for the silver colour. 110BCD Narrow wide, ring only, no bolts.
Sram Rival front mech band on
Good condition 7/10, not used for years but feels smooth!
