• Why are these things made of cheese? 50% failure rate on daughters Specialized Hot Rock. She can't squeeze brakes with gloves on (can without) so I need to adjust them inwards.

    2 min job becomes a mission.

  • Are you rounding the hex interface?
    It's gonna be partly down to the threadlocker that a lot of these have.
    I'd pull it straight out and use a bolt with a head rather than that grub screw. Threadlocker might still be necessary in the long term, then again, there is no long term for little kids bikes, 3 years maximum usually.
