Chainguide for triple/double-ring crank?
 

Does anyone know if there is a chainguide that can be used with three rings (XC crank)? A guide for two rings will also do. I do some UA-ish stunts and am always worried the chain will fall off, plus the noise the chain makes distracts me so much I can't concentrate on the technique properly (and it attracts too much attention from people around). Most guides I've seen only work with one ring. Many thanks in advance.

Rasheed is right on the money. Heim 3-guide is made by Montara Products. Click on the name to their link. It should be the bomb for three rings. I fabricated a copy with stainless and a skateboard wheel last year and it ran fine and was totally shiftable to all three rings. For two rings, the DRS is the way to go; though Heim does make a 2-Guide now too. Also, check out the Envy double-e2 - - burly bash guard that you can run a granny on the inside of and manually drop your chain to for the long uphill grinds.

truvativ shiftguide seems good.

Hmmmm, the Heim seems perfect. Thanks for the link. Simple design, 3 rings and not overly expensive.

I do have some questions:
Does it actually fit an XC crank, like Deore M440 or maybe even lower? I don't know too much about how they are attached and stuff.
Can I still backpedal in all gear combinations?
And what I really need to know is, will it stop the "kling kling kling" noise the chain makes while doing tricks? In other words, will the chain remain silent all the time?

Thanks again. :)

Nothing is perfect. Even the best, E13 DRS for 2 rings still has some chainslap. As long as you have a deraileur that moves, your chain WILL make noise. Keep in mind chainguides also make their own noises. So if you are getting a chainguide to stop noise...you are using it for the wrong application. Chainguides are mean to stop the chain from dropping. If you want no chain slap, go single speed.

A chainguide plus the sram rear deraileurs would like be a lot better for noise, as sram deraileurs don't jump around as much.

Yes it should fit a regular 44/33/22 XC crank. The Heim strut is stainless and, if I recall correctly, turned down a little bit around the mount hole; so that part is low-profile. It mounts behind your bottom bracket drive-side cup and should have negligible affect on your chain-line. Montara says it's backpedalable. My home-fabbed copy was not entirely, but that may have been due to my engineering. Follow the mounting directions that will come with it (as far as angle, wrap, etc.) and you should be fine. If you want some more info, read this REVIEW from Ridemonkey.com.

I thought chainguides didn't stop chainslap only the chain falling off the rings.

Have you tried a lizard skin on the chain stay for the noise? I'm always doing crazy **** on my bike and never hear any noises at all. Which bike are you riding?

im going to piggy back on this thread instead of making a new one, as its a kind of similar question (KIND OF :D)

Can you buy bash guards that fit on 3 ring cranks? Or are they only available as 2 ring + bash guard sizes?

I don't know anything about it but MEC has a triple bashguard on their site.

Blackspire makes what they call an XC Guard that mounts outside your big ring so you can still run all three. You'll need longer chainring bolts to mount it and you may need to check derailleur clearance, but that's about it. The reason I recommend this one is that it has the cutout for your crank arm (like the old Girvin Rock Ring had). To space it outside your big ring, it needs this relief to clear the arm. You could conceivably use any bash guard and hack out a relief for the crank arm but you might weaken it; the Blackspire is engineered to accomodate the relief.

The "klinging" noise you hear is most likely from your chain hitting the chainstay. Check it to see if it is marked and then buy a guard for it, it will eliminate a suprising amount of noise.

I already have a Lizardskin on the chainstay. So I guess the Heim won't solve the chainslap. Thanks Maelstrom, you saved me a few €€€. :) Aren't there any other ways of reducing chainslap (without going SS)? It's especially irritating when I ride down a long set of stairs (when I need to be really focussed).

Didnt I say that...

If it is really that bothersome to you, there may be another solution. If your chainstay will accept a Kore Chain Reactor, that will make the slap go away. It is spring-loaded, so it will take up whatever slack occurs. It swings back and forth too, so it is shiftable. Cambria has them HERE.

Crap, sorry. :o Probably wasn't paying attention.
dminor: That thing looks neat.

I have a feeling the KORE Chain Reactor might just be what I'm looking for. Thanks dminor!

Before you buy that piece of crap, you might want to read this first.

As with many reviews on MTBR, the half-literate launch into vitriol about something because they are ignorant or do not know how to read directions. Granted, the range of chainstays a Chain Reactor fits on are somewhat limited; but if it fits your bike, it should work well. The caveat here is not to take too seriously what you read on MTBR . . . especially if the person cannot spell or write coherently.

I read the MTBR reviews and take them with a grain of salt. Seems like most of them have a problem with fitting it on the chainstay, which should be easily fixed by using longer bolts but it seems that is too much to ask or something. Besides, it isn't all that expensive (IMO) so if it doesn't work out like I hoped I don't really lose much.

Good way to look at it :). You didn't say what bike, but as long as the chainstays aren't huge or have a severe taper, you should be fine.

Bike is a Giant Rincon. Frame looks like this (frame is the same, not the model).

I think that's just the kind of stays it will fit well on. Kind of constant diameter an not overly fat. You might still need the longer bolts, though - - the stockers are a bit short. The stays on my hardtail tapered sharply and the clamp had a hard time getting a grip on it.
