I have an old QU-AX muni with bmx style cranks, I currently have 175mm and would like something smaller
normally you should have a yellow hub and always one crank loosing ?
change your uni ?
I’ve sadly not once seen those cranks for sale separately in the decade since I owned a second hand 24" Qu-Ax muni with the old splined interface. I like you suffered with 175s!
I would normally recommend changing the hub, but then the issue is that they’re 48h and you’ll struggle to get a 48h ISIS hub.
It’s not overly helpful, but in this situation I’m with @bouin-bouin - keep an eye out for something to replace that relic!
I already have enough uni’s just trying to make this one more usable.
try writing https://www.henrys-online.de a mail. From what I know, they still have few left!
(they are not on the site, but I saw them in the warehouse last time I visited them, even a full kit with hub!
