Campy road cranks from the early classic fluted era ran a BB with a 4 or 5mm offset on the drive side so finding a cartridge ISO BB that’s asymmetrical and 112-114mm overall width is gonna do your head in time/cost wise. Yes, by grinding the tabs off you’re partly ruining a perfectly good set of cranks but they were made for some 30 odd years and there’s still probably millions of the out there so no biggie IMO. Either you run an offset BB and ruin the chainline for a fixed drivetrain or the tabs get filed off. Guess what I’d do?
Nah, i roll with(view) the Austere version of the forum, and choose myself to be avatar and sig free these days, cos I’m a grumpy ol man. Just thought it was a piece of Gold from the Retro guru that some one should preserve for posterity.
You’d be surprised how little time I actually have for the old stuff. I might chime in about the workings or dating them but I’m usually pretty frank about limitations of old gears, brakes and such. I’d just rather the kids have correct knowledge, info and perspective. I usually prefer modern stuff but find it challenging to get parts/bikes looking classic. Whilst there are some old parts that are briliiant and work very well compared to contemporary stuff, the majority of old stuff is for the most past it or limited in it’s use.
Potato: good for you. Rest easy knowing there are more strada cranks around than there are similar era derailleurs and brakes as they’ve suffered from rusted small parts and worn pulleys/springs etc. You’re actually just providing equilibrium. Check the spider webbing for cracks and if you have them use a small round file to file out the crack so it doesn’t become bigger and fail. Not a drama, quite common. Take away as much meat as you need to prevent future failure.
