Rollcii Square Taper Crank Bolt Dust Covers

Square taper cranks are having a bit of a comeback, like Nu Metal but actually good.  We sell 5 good square taper cranks, and these Rollcii Crank Bolt Dust Covers fit all of them.  Here's how it works:  Take the plastic ring off your crank arm fixing bolt.  Throw it in your roommate's drawer of warhammer figurines.  Install crank bolt to torque.  Lightly grease the threads on the dust cover.  Using a 5mm (not ball end) hex, install dust cover.  Just snug it.  It's aluminum, you don't wanna apply any real pressure.  Done.  Practically speaking these do nothing that the plastic washer doesn't do.  But psychosomatically, these will change the entire way you ride your bike.

Sold as a pair.
