Stronglight is a revered component maker most famous for cranksets and headsets. The firm started making cranks just before the second world war.

In the 1970s and 1980s the biggest French bike makers equipped their best bikes and teams with Stronglight cranksets. Most notably, Peugeot pro and semi-pro bikes were Stronglight equipped. Bernard Thevenet won two Tours de France using Stronglight equipment.

The firm is located in the French bike making capitol, St. Etienne.

Spindle notes:

For those buying our vintage Stronglight spindles, they have ISO square spindle taper. These are compatible with Campagnolo, Nervar, and T.A.

If you have a JIS crankset (Ritchey, S.R. most Shimano, Specialized and Sugino) the crankarms will sit about 4.5 mm closer to the frame when using an ISO spindle than if a JIS spindle were used.

And here's Stronglight's guide to the 1970's-80's spindles

Stronglight double spindle, 118mm for Stronglight 49D double cranksets. Used, $30.00

Many Stronglight spindles are difficult to identify. We think this spindle is for the 49D crankset, but we can't be sure.

We are pretty sure it is from the 1980s.
