Good and bad, but mostly good First off, it takes a bit of fiddling to re-hub your wheel. But that should be fairly obvious. Not sure why there's a freewheel, since the 5G transmission has a freewheel and a centrifugal clutch. The result is a ""disconnected"" feel when cruising as the wheel speed and chain speed go in and out of synch.There's no coaster brake in this hub, so you get the band brake. Don't bother, it's worthless, fiddly, and won't stop the bike. Better than nothing, but not by a whole lot. Certainly not worth the effort it takes to install and set up.A disc brake is much more effective and confidence-inspiring but is even more fiddly to install, especially on a bike that's not set up for it. Highly recommended anyway. You'll want to drill a hole in the sprocket for brake adjustment. The freewheel makes brake adjustment easier as you can rotate the chain backwards to align the hole with the caliper.You'll need a freewheel for your pedal chain, too, not included.Once you get everything working, the end result is a wheel that stays true, doesn't pull spokes and the sprocket alignment is both perfect and permanent.
