I've used this on a commuter bike and a track bike. They're very strong (and quite heavy), but can take a beating. It handles very well on the track. I definitely like how stiff they feel (which is a good thing!) when pushing with a bigger ratio (48x15) than my commuting ratio (48x17). Nice gloss finish to them and compatible with most square taper bottom brackets. Definitely recommend it as a starting crankset!
