Something happened tonight which caused my 9 speed sora rear mech to try to escape from my bike, unfortunately it tried to make its way through the rear wheel.
So I have ordered a new hanger, New wheels but I need to know wether the rear mech I need is short or medium cage?
It's 9 speed Sora triple with a 12-25 cassette, when looking at the explanation of rear mech size it says short cage will do max 31 teeth or 11-rangdoes that mean I am within the range or is the 12 sprocket going to throw that out?
Also that's not taking in to account the fact it's a triple chain set, so will I need a medium to take up the slack from the small front ring or will I be ok?
Cheers.
