Brand Information(click to expand)
 Often the forgotten manufacture of French cranksets after Stronglight and TA, Nervar cranks are often found on even the best French bicycles.  Many models will take the same chain rings as highly sought after (and thus expensive) models of the other French brands.  It is also important to note that mose Nervar cranks take standard threaded tools, so hunting down a special tool for removal is not required as with other French brands.
