Managed to get it off thanks to your recommendation!
The current bottom bracket is a Shimano BB-ES70, BC 1.37×24.
I have no allegiance to this BB, unless yall tell me I should?
I was going to try and just get a new BB and crankset – but don’t know where to start on that. If I’m going to do that, is the current BB relevant?
Hey all, thanks very much for the help thus far. Here’s a shot of the bottom bracket/frame with the crank off.
Since I bent the smallest chain ring, and the other two are worn, I’m hoping to do the bottom bracket, and chain ring – which I’m guessing, means, I need to get all componsents out of the frame – but the only two I’m able to name are: bottom bracket, and crank.
Not sure if I should be looking to swap out/purchase more?
I’ve attached the pic of the bottom bracket with the crank off.
Thank you very much for the help! I don’t have the wrench for the bottom bracket yet – I misspoke when I said it was cross threaded – it’s not the BB that’s cross threaded (into the frame) but rather the crank arms that are cross threaded (specifically the left one) into the BB.
I’m struggling to come up to speed with terms – what would be the correct bottom bracket wrench to remove this BB?
I’m also struggling to find a replacement BB and crankset – again, awash in terminolgy/sizes/brands. Other than a 73MM BB (thanks to you!) – I’m a little clueless as to how to piece together a good BB/crankset pairing.
Turns out the one that I got (via some neighborly help from a buddy down the road) is HUUUUUGE in comparison to my current one – like basically a 1:1 gearing on the smallest chainring.
I dig the bike, but I’m a little embarassed at how little I know about how to pull out the parts that aren’t working, and swap em for decent replacement ones.
