This listing is for NOS Campagnolo record square taper 10 speed alloy chainsets in that satin finish that Campagnolo did so well. Two crank lengths are available. The chainset requires and ISO BB of 102mm in length. See my listing for Tifosi BB's for this and Campagnolo still make a Chorus BB that will work.
Chainrings are 53/39T or 52/42T. This chainset will of course work with 8 9 or 11 speed chains as well.
This is the gold standard of alloy square taper chainsets. It is a shame they are no longer made.
This finish is acheived by the cranks being polished and then anodised.
The BCD is 135mm with a hidden rear bolt.
Campagnolo crank bolts are included.
