Chainring bolts - why?!?!

buckmulligan

Why do all chainring bolts have this infernal slotted-back design?! I've just bought a second-hand chainset that's got a seized bolt and spent a good hour yesterday trying to get it undone; tried holding the slot with a screwdriver, needlenose pliers and even the edge of a 1.5mm sheet of steel, nothing works adequately, the slot is just too shallow to get adequate purchase.

I remember a cheap FSA chainset that I had a few years ago had chainring bolts with a 5mm hex socket on one side and a 6mm on the other, why the hell is this not standard! I'm probably going to end up drilling the seized one out, but is there anywhere I can buy double-sided hex socket ones like this? :evil:

Have you tried soaking it in Plusgas?

You can buy tools specific to the job:

May be worth a try before drilling.

Token make chainring bolts with a double hex fitting. I have some on my race bike. Good weight saving over standard and available in various anodised colours.

I was very sad and bought the whole bling kit with the jockey wheels, cage bolts and heaset spacers in gold. My ridng buddy calls my bike ' 50 Cent' now! :oops:

I only put the jockey wheels in - they saved a full 4 g per jockey, which knocks 45 minutes off my return journey to Mars
