Which BB are you using on those hollograms? I've got a set in the cupboard I've never used because I didn't fancy using 30mm cranks with a BSA BB
Just some cheapo aliexpress thing. Issue is you need the extra long hollowgram axle. They’re not that common. Can’t use the standard 109mm one.
hmm maybe more trouble than they're worth then...
