Any suggestions for an upper guide that works with a 30t NW chainring?

Hi,
I'm going 1x10, and as I'm a weakling I've purchased a 30t NW chainring. Can anyone offer a suggestion for an upper chainguide that will work well with the 2mm inboard offset 30t rings have, and not rub the chain when it's at either end of the casette? It will be mounted on a 3x10 Shimano XT crankset and I'll probably keep my 32t bashring on there (unless I can find an upper guide and taco bash combo that works). Frame is a Banshee Rune V2. Cheers!

If it's a RaceFace NW you won't need a guide.

It's a OneUp, with a clutch derailleur. I'm hoping I don't need a guide and i'm going to try it without and see what happens, but my internet sleuthing suggests that it's a good idea if you're going to be riding rougher stuff (the Shore) reasonably* quickly.

*Or moderately quickly, but like a hack…

Or when it wears a bit.

My RF NW 30T has kept the chain on my hardtail riding the shore for at least teo years now.

No guide or bash needed.

I hear a lot of people telling me that a guide won't be required, and they are probably correct. Then I read about worn rings and race scenarios (not that I race), and I hear otherwise. Thanks everyone for the replies. I emailed a local manufacturer a few minutes after starting this thread, asking the same question. They got back to me super pronto and it appears that something for this application is in the works. I'll give it a go without a guide (but with a bash) for a while and if that doesn't work I'll hack my old chain guide with a file, saw and some spacers to tide me over until the real thing is available.

if you're a weakling who rides at a moderate pace and doesn't race, you'll be fine with a clutch d and n/w ring

yeah, for a non race scenario, I wouldn't worry about it. I very rarely drop chains on a naked ring, but the couple times I did were inevitably during races.

That's fighting talk! I'm a weakling on long boring forest service roads (or Old Fucking Buck), but not too bad on technical climbs. The technical climbs (where they exist on the Shore) are why I went with a 30t chainring. I'm a cack handed moderately/reasonably fast heavy lairy beast on the downs though. You should see my lines though, so so wrong, even when I try. And that's why I'm concerned about dropping a chain.

With a NW 30t ring? Do you get clearance on both ends of the cassette without the chain sliding against the guide?

And that…..is me!

I've never dorpped a chain with a 30t Race Face ring. It has never occurred to me that I should be pedaling a bicycle while riding downhill (WTF!) so I do tend to be in third or fourth even on long descents to keep the chain tight. I've not once dropped a chain though.

I thought the whole point of a narrow wide was to eliminate the need for guides and tensioners? You might want to check out octane one, they make them as well, I've been quite happy with everything from them so far!
