Actually lee_anderson, those quick links can be tricky if you don't get the right type for your chain. The pin has to seat fully or it'll just pop off again when you pedal hard. For a simple fix it's okay, but a proper chain tool and a new pin is way more solid for the long run.

Ever consider they just want what works for their life?

Bought a 'vintage' denim jacket with plastic buttons once, totally ruined the vibe.
