aluminum chainring bolts

[been_jammin]

know why aluminum chainring bolts are hollow? to save work when using an extractor... after the bolt head shears off there's no need to drill it before threading in the extractor!!! killed one when removing my granny... that was a 3 dollar bolt, dammit!

figured alu would be ok for the granny chainring given the low torque applied when pedaling that range of gears... plus the LBS was out of steel chainring bolts (how is that possible?)

(answer to rhetorical question: steel bolts $3 per five, alu bolts $3 ea)

I used the two small grunts method of measuring tourque when installing the bolts - should have used my tourque wrench

the steel are hollow too but i've never heard of one of them rounding out. unless they didn't use grease the bolt threads rusted to the backing bolt.

for some reason, no one has steel bolts. i've called everywhere here in SA.

they actually aren't a good idea for granny rings either. if the chain falls off and catches on of the heads it's chew it like my two front teeth and K9s through a spicy polish sausage.

aluminum for cahinring bolts, crank bolts, der (front or rear) fixing bolts, brake and shifter fixing bolts, and stems make me soooo nervous.

steel chainring bolts, even the single ring type, just bought 2 packs
