I'd be trying: - hail mary with vice grips on the remaining bit sticking out - drilling the whole thing out and using as low profile as possible a bolt/nut combo in place of the threaded hole.

vikingstrike posted:Use the BCD at the bottom. 120/90. Then just buy whatever size rings you want (52/36 etc) Thanks, do the bolts come with the chainrings, or is that something I have to order separately? I'm guessing that spider is stuffed because of the missing bolt, do I just need to find a BB30 compatible spider? Sticky Date fucked around with this message at 23:45 on Apr 23, 2024 |

You may be able to reuse what you have though. Bottom bracket doesn’t have anything to do with rings. Bottom bracket is related to the crank itself fitting on your frame. The BCD tell you the bolt order and spacing needing to fit rings to the crank.

The spider is specific to those cannondale cranks. Chainrings bolts are usually pretty generic so you probably don't need anything specific for those rings. Kind of a weird bolt pattern for road rings though so if you can't find some another option would be to get direct mount cannondale chainrings that don't use a separate spider but those cost more. https://www.cannondale.com/en-us/gear/components/cranks-and-chainrings/chainrings/hollowgram-spidering-8-arm you need a special tool to remove the crank arms from the spindle that goes through the bottom bracket as well as one to remove and install the spider. Although I think the spider lockring tool is some sort of a more generic BB tool. And the crank arm tool is basically just two threaded plugs that create an extractor.
