SRAM X9 rear mech sizing

evenin troops,

I’ve just purchased a X9 rear mech via the classifieds.

Was advertised as a Medium cage.

Mech arrived today and I could swear it matches up size for size with exisiting Long cage mech that I’ve on my bike.

My question is does anyone know a quick, easy way of confirming the cage sizing on a mech???? I’m guessing measuring the thing is one way.

many thanks 🙂

quick check of an X0 medium cage mech – cage size c-c is 75mm

cheers pal, just measured mine…..looking at approx 95mm centre of jockey to centre of jockey….LONG cage.

what a scunner 🙁
