I bought a training wheel based on Rigida rim, a Shimano RM30 (8s) hub and Shimano 105 (5700) cassette.
Tried to fit the new wheel, but it simply wouldn't go on - catches badly on the lock nut. To make things even more complicated, it appears that the hub is designed for an 8speed cassette. Is it likely that the hub has a spacer still attached, thus explaining why the frame is catching on the locknut?
I took it back to the shop where I bought it from and they said it should go on if I 'pull hard on the frame'. I didn't quite like the sound of that and besides, it sounds like a lot of bother too!
Even though it will take a quick release skewer, the ends of the axle are threaded, whereas there are no threads on my Fulcrum 7s. Sorry if this sounds like a newbie asking stupid questions, but since the threaded ends will be sitting inside the dropouts, will I damage the dropouts?
I appreciate any and all advice!
