Vintage Nervar 631 / 633 crankset with original bottom bracket. Crankset has FRENCH pedal threads, and bottom bracket has FRENCH threads as well. Crankset is 50.4 BCD, with 44T - 52T chainrings. Bottom bracket is 117mm width. Vintage pre owned condition with light rubs, scrapes, etc. Threads and tapers are excellent. Chainrings have good life remaining. One of the crank axle bolts looks to have had a hole drilled in it at some point? Bearing surfaces look very nice. There is one very very small ding on the axle, pictured in photos. Overall fantastic. A great French crankset and BB! Please review all photos and feel free to message us with any questions. Orders are always shipped quickly, next day USPS Priority.

As is. Threads are good, pedals are included and they spin well. I believe this can off a Schwinn sorts tourer.

The rings look okay, but I haven't tested them in use. They didn't seem bent when I removed them to clean. I don't have the original bottom bracket anymore, but after putting it loosely onto a JIS spindle, the arms appear to be designed for ISO tapers and should not be installed on a JIS (Shimano, etc) bottom bracket.

Approx 170mm, might not be exactly 170. Arm surfaces show scratches, small nicks, and finish wear along the edges, while the spider arms and chainring bolt holes have marks from previous chainring mounting.
