Taking the stock setup to a 1x9, using the middle ring as the 1 up front. I pulled off the front derailleur and took some links out of the chain to increase some tension, but that was no good as the chain would drop on everything. Put the front derailleur back on and locked in the middle position, ok, but I want to get rid of the other two rings.

I'd like to replace the big ring with a bashguard (BBG?) and get a chainguide (e13?) to keep it on. Problem is that there are so many e13 and similar brand models that I have no idea what I need.

Also, should I get a shorter cage in the back since I don't need the full coverage anymore?

Any input greatly appreciated. I hope I don't have to buy a whole new crankset, as I'd like to keep this mod fairly affordable.

edit: K2 Flying Monkey if it matters.

Go with a lighter and simpler setup:

bashguard on the outside (pretty much whatever one you want), and an Ngear jumpstop on the inside.

I ran my long cage xt derailleur with no issues, and I didnt even shorten the chain because I couldnt find my chain breaker

This is the setup I just converted to, and I absolutley love it. Raced it in a 6 hour race yesterday, on one of the most technical trails I know of and never had a problem with chain drop, except for once when I had a really bad crash and it came off the bottom of the chainring...it was still on the top though so it just pedaled right back on

I would just go for the MRP 1.X guide, it's lighter than all front derr. and it works awesome. I used a bashguard with the n-gear and it fell off every once in a while (during a race). I have had my MRP 1.X guide for 1 year and my chain has never fallen off. It's mounted from the bottom bracket but I think they're making one mounted from the seat tube.

awesome, looks good, but I'm not entirely convinced that the design of the ngear will keep the chain on in really rough stuff.

Looks better than the ngear, but it doesn't look like I can run a bashguard with that, correct?

One thing you will need to consider with the MRP guide (1.x). It dosen't have a bottom chain guide roller on it. One problem that I have had because of this is the chain will have a tendancy to jump off the bottom front ring when riding over bumps and then slightly back peddeling will cause the chain to jam in the guide (common problem). It's happened several x's on my mojo, at one point it almost cost me some time at the local hospital or worse.

MRP just came out with a new version of the 1.x that now has a lower chain guide pully.

If you ride more x country with out many bumps you may never have a problem. If you are like me and ride a full cush bike hard over roots, rocks and bumps than you will have problems, therefore spend the extra cash and get the 1.x with the lower chain guide pully.

It depends on how you want your setup. To me the E.13 stuff is mostly for downhill applications. It is to big and beefy for my taste. I also tried the Blackspire Stinger when I had 2x9 setup. It was ok, but i didnt like the extra friction. I finally settled on 1x9 with BBG outer and BBG inner. I have had ZERO problems with this setup. I also find this setup to be reasonably lightweight. I have medium cage der and removed 4 or so links. Big-Big + 2 method.

Get a single ring chainguide, pretty much any DH guide will work. Since your Monkey has not ISCG tabs, your going to mount using BB and most guide come with adapters.

IMO, get a E13 LS1+ and your all set.

Believe me, nothing works better than DH type chainguide for keeping things tight and working.

The MRP 1x is great for some applications, but not the best for AM riding.

The sandwich type setup using 2 bashguards also works well, but has its flaws - chain can still come off rings, chain bounces around (noisy) since there is nothing to take up tension on chain.

There is no substitute for what DHers have already figured out, if these other guides worked as well Im sure youd be seeing World Cup DH riders using them. Since they are not, that says something. Heck look at most Super D riders running 1x9, their using DH guides too.

I agree, and they are making them much lighter for us non DH'ers

^^ I agree!

Get something like thee MRP 1X with the guide on the bottom, or the DMR Elite. Im having similar issues but apparently cant mount anything to my BB so am pretty screwed.

If you get a light DH type then im sure you wont regret it, i hate worrying about the chain whenever im riding hard!

Can anyone tell me if the 1.x guide will work with ISIS type bottom brackets or was it designed with external bb's in mind? Or does it even make a difference? I'm a ham-fisted mechanic and am having problems getting it set up with enough clearance on the outer portion of the chainring.
