Nervar is one of the forgotten brands of French component manufaturing, and this is unjust. Nervar parts were well-made and used on a wide range of French and Italian bikes.

Because Nervar used standard ISO spindle taper and crank-arms puller threads, unlike many other French parts, Nervar component are easy to service.

Spindle notes:

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