I've seen some custom harley-type bikes wit hthe rear sprocket doing double duty as a rotor.

This seems to be a peculiar way to design a bike. It seems there is too much conflicting stuff going on (i.e. greasy chain vs dry rotor surface)

anyone comment on these? (other than "harleys suck")..

The 'sprotor' I've seen this widget. As far as asthetics, it's a cool notion. But when it comes to function... seems like a bad idea. With that sort of design it seems to me that:

1. Chain would get nasty quickly, due to brake dust.
2. Potential braking issues, due to chain lube getting onto the rotor face.
3. Wear issues. materials that make a good rotor, are not the best for a sprocket and vice versa.
4. CHROME?! I looked at one online to see what the deal was.. and the 'sprotor' was chromed. Um... ok


In short... seems like a fine notion for a showbike/trailer queen that's not expected to go much beyond the trailer to the show ring. But for a riding bike, seems foolish, IMO

Cool in an "Oohhhh! Look at that!" sorta way.

Other than that it seems very impractical.

I don't see any lube on that chain.

It's a cool thing if your only riding your bike a few miles a year...otherwise would be a pain in the ass to keep clean and working
