Yep, this is a Nervar Sport, which, like a Stronglight model 49 outer ring, is compatible with TA Cyclotourist arms. However, like Stronglight mod 49 , the inner circle is different, 128 for Nervar, 122 for Stronglight. So i f you use a Nervar outer ring, you must use a Nervar inner ring - I don't k now of anyone else than made a 128 BCD ring. A 128 BCD ring should go down to 38T, but I've never seen one smaller than 40T.
