[Closed] Short or medium cage rear mech?

Sorting out my dh bike and trying to figure out what size mech I need. I'll be running 1x9 with an 11-34t cassette on a Bullit which I don't think is [i]too[/i] bad for chain stretch when fully bottomed out. I prefer the clean looks of short cage and would be nice to get it out of the way, but will it work ok with the big range cassette? Been offered a Shimano 105 (guess that's a road one) for £15 posted, would that work ok or would I run into problems with shifter or cassette compatibility? I'll be using an old shimano deore shifter, it may be deore xt.

A short cage will work, but a road mech has a max capacity of 27/28 teeth.

If you got a new smaller upper jockey wheel it may work. Or it may work anyway, just not very nicely.

9 speed road mechs work with 9 speed mtb shifters aswell. Dunno about 10 speed stuff though.

Ok so I'd need a short cage mtb specific mech for it to work then.. can't find many of them about for cheap so might just go with a medium SLX or something..

I don't know if short cage MTB ones exist do they?

I'd just go with an SG cage SLX or XT shadow. Should be able to pick one up cheap.

PS technically I think shimano refer to SG as long and SGS as super long but I think most people refer to them as medium and long.

Stuff like the Saint looks to be short cage but it's also very expensive.
