Hello and thanks for checking out this new Campagnolo Record 10-Speed Alloy Crankset! This crankset will come to you in the true “NOS” new-old-stock condition seen in the included photographs. 170mm length, classic 53/39-tooth chainring combination. Compatible with ISO square taper bottom brackets. Increasingly hard to find in NOS condition. Please see the included pics of the actual crank you will receive. Contact me with questions, I will do my best to answer them.
