Did you check out the Crank Brothers Cobalts? They’re foam and lock-on at just a measly 65g (almost half my LS Moabs at 113g) and as with all Crank Brothers gear, they look pretty sweat. Plus, they look rather durable too. Check em out!
These things rock, I’ll be getting a second set for my project bike shortly. Unless you dump into some rocks or sharp branches I don’t think the cobalts are going to wear out.
