I have a few old ones but this is the only one available for sale
A couple listed here: http://www.retrobike.co.uk/forum/viewto ... 463#437463
Most of mine are small/medium, around 18 pit to pit so this OK, but is slightly too big so doesnt get worn.
I have a green and red cactus cup but if you come across a small/medium I would be interested to know.
Its a medium and measures 20'' pit to pit.
