Short cage 10sp rear mech?

The Northern Monkey

Wondering, does anyone do a short cage 10sp rear mech?

Thinking of putting 10sp on my canyon to give a better range for when xc'ing. Currently its a bit tough to get up them hills.
But I only have a single ring up front and I dabble in DH, so don't want a long cage thats more susceptible to rock strikes/breaking when I inevitably bin it.

yes.

Never been on the shimano site... man thats terrible.

Anyways, Shimano XT 10sp Short Cage?

I can find a road 10sp short cage but not an xt....

The Northern Monkey

Ahhh wait.. GS not SS. doh.

So they do a medium but not a short... that makes sense.

I know SRAM do short cage in X7 and X9 mechs

And you can get a 36 tooth on the back then which would really help if you want to get it up the hill

Then there's the new Saint and Zee stuff coming in the next couple of months. That's what I'm holding out for.

I run a short cage X9 on the hard tail with 12-36 cassette, 34t up front. Little slack in that and shifts great.

And yeah, definitely don't want a long cage for a single up front. Not sure about using a short cage on a full sus even with single ring though due to movement of the chain as the suspension moves. Certainly fine for a hard tail though.

short is fine on most sus frames.

Could go for the XTR GS shadow which will reduce chain slap as well or wait for the Saint/XT/SLX to come out. They may be medium cage though, not short (except for the Saint)

I'd don't see how a normal short cage reduces slap. It moves the chain closer to the stays

agg25

The shadow has a chain slap reducing mechanism in it which holds the chain tighter, google it

Chunkers1980

'the shadow' there are lots of them. I'm fully aware.

agg25

well as it was in reply to my previous post which mentioned the XTR GS shadow didn't think I'd have to repeat myself but anyway, this one -> http://www.artscyclery.com/descpage-SHRD980GS.html

Chunkers wasn't talking about the 'plus' clutch not working, he said "I'd don't see how a normal short cage reduces slap"

basically there is less chain in the loop as you run less gears,

Less chain = less range of movement pretty much on a simple terms.

That's my understanding, or something like that. That's what I'd read anyway when I did my 1x10 hard tail, and pretty much the advice from SRAM too. Works for me anyway. Good enough that I don't need to consider a chain device and it's not clattering on a bit of gnarl. Unlike my 2x10 on the big rig which has a medium cage. Bigger ring has more tension but it slaps about a lot still and may end up with a chain device.

Yes, but some is offset by being closer to the stay?

the mech isn't smaller, thehanging cage is so distantce from the frame remains equal, but there is less chain so generally the system is under more tension.

Less leverage on the spring maintaining the chain tension. A longer cage (ie lever) requires less force to pull the cage forward allowing slack. That's how I thought it worked anyway.

The cage length debate is more about gear range though.
