Vintage Campagnolo Record Hub Measurements

Campagnolo Record Hub Set

If you are looking to build a set of wheels? Vintage Campagnolo Record bicycle hubs are perfect for the job. They were in production from the 1970’s to the 1980’s and supplied in several Campagnolo group sets namely Nuovo Record, Record and Super Record. There are plenty of used hubs available for purchase on the internet, so I have created this page to provide the wheel building measurements to help you calculate the spoke lengths. There are many free online spoke length calculators.

NOTE:
The hub illustrations in these screenshots do not represent vintage Campagnolo Record hubs, (as they didn’t have a disc brake mount or a freehub body). However measuring process is the same regardless of the type of hub, so the dimensions shown are the part you need to know. All dimensions are in mm.

Front Hub Measurements (100mm O.L.D)

These are my measurements of a vintage Campagnolo Record front wheel hub with over locknut dimension of 100mm.

Rear Hub Measurements (126mm O.L.D)

These are my measurements of a vintage Campagnolo Record rear hub with over locknut dimension of 126mm. Note that these hubs were also be available in different axle widths eg. 130mm, so some measurements would be different.

Using a Spoke Length Calculator

There are quite a few free online spoke length calculators. The calcualtor I used was on the www.prowheelbuilder.com website. Now that you have measurements for the hubs, you only need to enter 3 other pieces of information to calculate the required spoke lengths;

  • the ERD (effective rim diameter) of the rim you want to use. I built a wheel using 1980’s Mavic Open Pro clincher rims and the ERD measurement was 600mm.
  • The lacing pattern ie. 2 cross, 3 cross etc.
  • The number of spokes in the rim which will be governed by the number of holes in the hub = number of holes in the rim eg. 32, 36 etc.

When building a vintage wheel for rim brakes, the rear wheel will typically require shorter spokes on the drive side. The front wheel will have the same length spokes for both sides of the wheel. Spoke lengths are available in 2mm increments. Read more about the parts I chose for my wheel build when restoring a Colnago Nuovo Mexico.

Learn How to Build or True a Wheel

I have created an article sharing the information I have learnt on how to build a wheel or to true a wheel. Once you learn how to true a wheel correctly, it is not much harder to build one from scratch.
