For sale I have some nice TA duralumin 6 hole chainrings (centre of hole to hole is approx 76mm). Superlight for their size they weigh approx 55g-60g
One of the 50's has barely been touched, 2nd a little more & the third is still very good. The 51 is about the same as the last 50 and is very much useable.
Full close ups of the teeth etc can be sent directly so you can asess actual wear. The best of the 50's is the one on the left of the two with the next best in the same shot. Obviously the most worn is seperate as is the 51.
In order of wear I'll take £13, £11 & £8 each for the most worn 50 & the51
Postage will be 72p for 1, £1.01 for 2 or 3 and £1.77 for all 4 (In 2 packages as it'll be too thick for large letter) if in one single package it'll be £2.10
