Looking for some spoke lengths
Coming out of lurker mode here to see if I can get spoke lengths for current (9-10-11 spd) Campy Record hubs, 32 hole, going 3-cross to Ambrosio Excellence rims. There seems to be some uncertainty on their ERD. I've been on tubies for an age and am hopelessly behind the times.
Alms for the old... |

There seems to be some uncertainty on their ERD. I've been on tubies for an age and am hopelessly behind the times. As Andrew Muzi has advised, measure the ERD of the rims you have. The online spoke length calculator I often use: https://leonard.io/edd/ lists two different measurements for these rims. So, for the rear hub, you're likely to want 292mm & 294mm spokes for one measurement and 294mm & 296mm spokes for the other measurement. That's if I've picked the right hubs and you trust online spoke length calculators. Certainly the above spoke length calculator has worked for me on the times I've used it. -- Dennis Davis |

I used the-two-cutoff-spokes-trick I found on the web, and the webpage calculator Dennis pointed me to. My numbers for the rear matched his so I had the correct hubs. Front was then easy. Going to sharpie these lengths on the inside of the toolbox lid. And, boy, did Campy make a lot of different hubs. |

A web search with keywords "measure ERD spoke", or similar, will show up several pages describing how to do measure the ERD. Mike T's wheelbuilding site: http://miketechinfo.com/new-tech-wheels-tires.htm looks comprehensive. I quite like the description in: http://miketechinfo.com/ERD-measuring.htm The use of an elastic band in the above is slightly Heath Robinson[1], and appeals to me. Roger Musson: https://www.wheelpro.co.uk/wheelbuilding/book.php (I *must* buy a copy of his book.) includes a comparison of spoke calculators: https://www.wheelpro.co.uk/support/s...h-calculators/ [1] https://en.wikipedia.org/wiki/W._Heath_Robinson -- Dennis Davis |
