I'm switching to a 1x9 setup on my full suss and am wondering what ratios other people use. I generally do everything in the standard middle ring on my triple which I assume is a 32, so I was thinking of going to a 34t chainring and a 11-34 cassette.
What would you recommend?
Also, I think I heard somewhere that with the larger cassette I might not get away with a short cage mech, any experience of problems with that?

Should be fine if you're only using one chainring.
i'd stick with your 32t up front and 11-34 on the rear should cover most requirements.
I'm running a 32 chainring with a 11-34 cassette and a short cage Saint, works a treat.
running 34 up front with a 11-34 rear
it works for me 🙂
If you have the chance to go 10 speed and run a 36t rear with a 32t front, then I think that combination would be even better. I run 32t front by 34t rear and it's fine for probably 85% of UK riding, but I struggle on longer rides in places like the Peak and Lakes.
Short cage rear mech will be fine; the Saint version has a tension adjust that raises and lowers the cage in relation to the cassette and this allows you to fine tune when running a short cage with large sprockets.
I'm using 34 up front and 11-34 cassette - seems OK.
What are people using to keep the chain on the front ring, in the absence of a front mech?
At the moment I don't have anything, and I loose the chain on rocky descents...
32T and 11-32 cassette, with an N-stop and bashguard.

Pauls Components Chain Keeper, very neat and works a treat!
out of interest will a standard singlespeed front ring work with 1x9 or indeed 1x10? Or do you need to use something narrower?
34 front, 11-32 rear with a shortcage road mech and a DMR chaincage up front.
shortcut, what do you mean by standard? singlespeed rings are available in 1/8th (too fat for 1x9), 3/32 (too fat) and narrow/9spd (OK for 1x9).
I have a narrow MRP, it works nicely

Only just gone 1x9 and have left the mech on (after removing shifter and cable) and can't really see the point of spending more.
Running 36T ring with an 11-32 on my BFe. Its fine for the Surrey Hills, but a bit of a grunt in the Peaks.

E13 LG1 here. Not the lightest option compared to the "top only" devices, but it stops chain slap, and the taco has had a decent workout over the last year. Never dropped a chain.
34T with 11-34 cassette, med. cage SRAM X9 and an e.13 XCX. Suits my needs. The XCX works fine after a few fitting problems. I haven't lost the chain since I fitted it. I went with a shorter mech because I needed a new one anyway, but I've got friends with basically the same setup but with a normal, long cage mech. I personally think it looks a little silly and it does bounce around a lot more than a shorter, but there seems to be very little in it in terms of function
3/32 (too fat)
are you sure about this? I'm pretty certain I have a 3/32 running with a 9speed chain, but i could be wrong.
but a bit of a grunt in the Peaks.
Much less of a grunt than a singlespeed though.
34t front, 11-32 out back. I use a Gamut P20 to keep everything together and an X0 short cage rear mech

3/32 is 7/8 speed
I use one of these: http://www.sjscycles.co.uk/product-Thorn-Thorn-104-mm-PCD-4-Arm-Reversible-Single-Chainring-3-32-Inch--Black-11054.htm
with my 9sp chain. The taller teeth make a tiny bit of noise against the chain when in the 34t sprocket, but it works fine and the chain sits on the chainring no problems.
Thanks for the chain guide suggestions.
some manufacturers use 3/32 when the teeth are actually narrower, worth checking, I know some steel 3/32 don't work with 9speed chains.
Thanks for the link IanB, that's the same ring i use but couldn't remember where i got it!
As he said, I use a 41T with a 12-25 cassette for commuting and it works fine.
