• Could anyone help with this please? I've got no idea what this crankset is. It's 175 mm long, 135 BCD, triple, square taper. Had/has Campa chainrings on. Previous owner says it's a Campa Xenon but I'm not sure at all.

    The right arm has 564, the left one has 554 engraved onto them.

  • If the PCD is 135mm, then it's Campagnolo, or at least Campag. spec.: Miche are the only people I can think of who produced Campag. spec. cranks and I'm not sure they made a triple.

    With those markings on the back, they're 1995 or later: before then, they would have had the crank length, pedal eye threading and a date code.

    The shape of the cranks around the crank bolt indicates that they are from the bottom half of the range. Campag. didn't make a triple for every groupset, nor were they all offered in black so you should be able to pin it down, if you're that bothered.
