tay...@gm...l.comGot these because I didn’t want to buy the shimano specific chainring bolt tool. Ended up borrowing a friends chainring bolt tool, but even then, I kept stripping the nut. Took a 3/8 drill bit and drilled out the old nuts and bolts, slapped these bad boys on there with a little anti-seize and we’re on our way to greatness! Love the double hex design and the fact that their steel and painted black. 10/10 would recommend. 10/10 would recommend to not get the shimano tool and just drill out the old P.O.S.
