Simple BB (Prowheel) is loose - any suggestions?
I have a Gaint QSR City which I am trying to fix for my mother.
The BB is a single ring made by / called ProWheel.
It's not on my radar as I am used to mtn bike BB's but as it's very loose & I was wondering if there is a simple tightening fix I can do with limited tools.
Any suggestions would be most welcomed.
Thanks
FM
