    Removing outer chainring question

    Trying to remove the outer chainring on my 84 Sakae CX crank. You would think its as easy as "just remove the bolts" but all the aluminum bolts seem to do is get rounded off.

    Im going to try again with some PB blaster, and does anyone know the EXACT size these bolts are, and metric or standard.

    Worst case scenario, I guess they are so soft I'll drill them. Then for replacements can I use some bolts or nuts and botls from home depot if I can't find suitable replacements at the LBS?

    I swear these bolts are just aluminum plated plastic.

    They're 5mm.

    If it will make you feel any better, you'll want to buy new, shorter bolts to use after you remove your outer chainring anyway.

    Several, mostly not name brands.

    Are they allen-head bolts? These take a 5mm allen wrench. The back side of the bolt is slotted so you can hold it in place while loosening the front.

    Buy proper replacements at a bike shop and grease them well so they don't seize up again.
