Subject: [CR] spoke-length calculation


Using a couple of internet spoke-length calculators, I established spoke-lengths for some vintage track wheels I want to build..but, I wanted to take advantage of the collective intelligence here to make sure I have the right lengths before I buy spokes.

These will be conventional track wheels, using vintage Campagnolo Record high-flange track hubs and Fiamme red-label track rims. 3x 32-spoke front. 4x 40 spoke rear.

The calculators said that the rear would require 300-301mm spokes. The front requires 298-299 mm spokes. Does this seem right to those of you more expert in this than I am? And if these are not correct lengths, what would you suggest?

Thanks.
