• Quarq hidden bolt, anyone have a spare?
    I seem to have got mine stuck on the chainring

  • If they're the same as the sram hidden bolts then you should be able to knock it out. Just find a rod the right diameter, support the ring from the underside and hammer it out.

  • That would have been better than the approach I took which was to re-thread the sleeve to push it out only to have to use pliers to separate them again.
