I have one set of 5 VIS cranks in use, a set of
Nervar 631/633 that I acquired in a trade with some $$ thrown in. I got them along with a Nervar British-threaded BB, but I am currently running it on what I believe to be the original Stronglight bottom bracket in my Allegro. I am not in love with the 42/52T chainrings, though, and someday I will break down and get myself a set of 30/46T or similar. Here is the obligatory pic of the velo in question -
- and no pic at this time, but I DO have set of T.A.'s in the workshop with chainrings even less useful than these. I'm not a French racer in 1967, so 45/52T by 14-24 doesn't quite make it for me. Then again, I got the crankset and an amazingly clean T.A. French BB for $20 along with the world's rattiest 54 cm Gitane Grand Sport in this hemisphere. Someday I will find the appropriate bike to fit them to.
