What can I do here? As I want to keep the crank, could I unscrew the BB now, leaving it on? Apologies if that question makes me sound like a moron, I haven't worked with bottom brackets before. I've already tried penetrating oil, doesn't seem to make a difference.
All pointers appreciated!
Well it's stripped. Sometimes we forget to check if there's a washer in the crank and that will do it. I can't tell which Stronglight crank you have but early ones used a proprietary 23.35 puller. What size is your puller?
Inexperienced mechanics will try a 23 mm TA puller because it 'feels' like a good fit but that will strip the threads as well.
