- What chain device for….
A retro GT frame?
Currently got an old 90s frame set up as a SS commuter
Was considering making some adjustments to allow me to run it 1×9 (I’ve got an old drivetrain knocking around)
But given my experience with 1×10 I know I’ll need something to stop the chain coming off.
Any ideas? It’s a square taper bb with a 28.6 seat-tube and no iscg tabs. I’m presuming my only option is to go 3 x something as it was originally or just learn to pedal harder and keep it as a single speedPosted 4 years ago
