I was rebuilding the pub bike for a charity ride tonight and noticed the b-screw on the x9 rear mech was bent. Googleing around, I can’t find a replacement for a reasonable sum. Does anyone know the screw size that fits and/or a supplier of said screw?

I have a local family run hardware shop that are perfect for bits and bobs like that, if you have anything similar, take the screw with yyo for comparison.. worth an ask.

I snapped mine on my X0 mech and replaced it with a bog standard M5* bolt with a couple of nuts on it. Works fine and I keep a couple of spares in my pack now (not needed in 18 months so all OK)

*may be M6 but pretty sure it is M5
