Hi Guy's,

Hope you can help.
I want to run my bike with 1 gear up front and 8 gears at the rear.

The front chainring is a middleburn 38T which I don't want to change.

I.m currently running singlespeed with 38T front and 15T rear.

I am planning using a Sora 12 - 25 rear cassette which will give me the wee bit extra gearing I require.

I would also like to use a XT rear mech but before I spend any money I'm confused about wether to buy a long or short cage.

Your help and advice will be much appreciated.

Kind Regards
Supergunn
