Oh, decided not to put on the Ultra FW just yet, because it is a 23T while the current Maillard is a 28T, and daughter wants/needs the 28T to climb the local hill. When she's off a camp this summer, I'll replace steel cottered crankset with a compact drive, then swap in the 23T. Actually going to go through the whole bike this summer and surprise her when she returns. Gotta find a Maillard FW remover so I don't have to keep running to the bike shop.
