I'm no bike mechanic, but I do have a lot of patience and mechanical aptitude. This unit failed in every way. It's made of very light aluminum and plastic. The sizing washers are all plastic. The bearings are pre-sealed, and if you accidentally move wrong, everything falls apart, leaving you with sealant all over your hands and - seriously, folks... don't bother. Waste of time, at least for the Hyper SpinFit. Can't even return it because it's mauled up. Waste of money and time. Fooey.
be very very careful to not mess up the brittle plastic bearing dust cover
