    Is there such thing as a chainguide that won't catastrophically fail??

    E13's believe it or not do fail, and when they do, it's bad. Meaning chain wedged between the backplate and the chainring locking your pedals kind of bad. They also drag like crazy and the bashplate gets bent into the chainring when it takes a sideways hit. They're out.

    My Gamut just dropped chains on the last 5 rides. On the last ride, it lost the chain from the lower roller as I bottomed out the back end through a G-out and it ripped my derailleur off and put it into the rear wheel. This is not the first time in recent history that it has left me walking out of a trail. I hope they warranty this thing and maybe fix it so the chain can't escape when it's set up right since the concept is real nice. I would really like to get the derailleur replaced too as it was pretty much brand new and expensive as hell (new X9) but I doubt that's going to happen.

    Are there any other companies that makes guides that won't horribly F me out on the trail when they mess up and cost me lots of money when they destroy my drivetrain? I know nothing is foolproof but being able to repair it quickly and easily is what I'm after. I'm not too keen on the LG1. I hit way too much stuff, especially from the side. MRP's don't clear on my frame since they don't clear the chainstay yoke. And before anyone suggests it, yes, these guides are set up properly.

    You haven't left yourself a whole lot of options LOL. Blackspire? Something simple like Transition's guide? Hell I don't know what to tell you.

    Parts on DH bikes fail. With the amount of abuse they they have to deal with, there's no way a part like a chain guide will last forever. That said, you're just about the ONLY person I've heard complain about e.13's guides (excluding the LG1- what a POS), so perhaps you've either just got extremely bad luck, or don't know how to set them up properly. You can't really complain about it getting bent when you smash into something either, it's not like it was designed to get smashed onto things sideways.

    Try a vanilla style MRP with the upper and lower rollers with the large back plate that sort of sandwiches the chain between the bashgaurd and backplate. If there's a guide that will take the abuse better than any other, it will be that guide.

    Yeah I wanted to use those old MRP's when I first built the bike up, but the R9 frame won't accept a full backplate w/o hitting the chainstay. I actually just looked at their site and the link to Jenson and some of those look promising. I always liked having the rollers directly over the chainring on both ends so there's no gap at all.

    I think I had one of the older SRS guides. Their over-hyped bulletproof Lexan sucked. The rest of the chainguide was made of super super cheap plastic. The roller dragged like you would not believe. I'm not running anything like the LG-1 unless there's something that completely cradles the bottom of the chainring. Most of the stuff I hit is in narrow chutes from the side (you should see what's left of the sides of my pedals).

    I have enjoyed the Gamut guide up until this point. Out of sight, out of mind. No maintenance to be done on it besides roller spacing and replacing a couple chainring bolts that had rattled themselves out.

    I'm gonna have to agree. I run a gamut guide and its hard for me to imagine how you're losing a chain every time unless something is horribly out of whack

    Kevin, I've had this Gamut on my bike since the end of lift season last year. It has been perfectly fine since then. The only thing that has needing adjusting is the lower roller spacing. I think it might just be getting worn out and flexing too much or something, no idea. The E13 guides were also set up by the book. They're losing the chain because there's just enough gap between the bash and the upper guide/roller than the chain can squeeze through when it's flexed. Hence why I like the MRP idea of the roller going over the entire gap on the top and the bottom.

    I don't know Gordon, but I've ran two LG1's and I've never had a problem with either. Set yourself plenty of time to set it up, and don't be lazy, be willing to use the gold washers to get the guide chainline correct and rolling smooth.

    A lot of guides out there work really efficiently when setup correctly. I don't doubt your ability to set it up properly.

    With that I say LG1. Mount it with the BB Adapter and you'll be fine with a taco. I've been running a taco on my LG1 mounted to ISCG tabs and I've smacked it plenty. Its fine.

    You've definately got it setup wrong. the only way there could be a gap big enough for the chain to get caught between the upper slider and bashring is if a) the bashring is too small, b) the slider is not set to the proper height, or c) both.

    When I first started using the SRS I would have the same thing, but it was because my bash was WAY to small, and with the slider set at the proper height there was still gap. With the proper size bash and proper slider height there will be no gap and what you describe will not be able to happen.

    And as far as the backplate being made of "cheap plastic", you need to lay off the bong (that might be why your bike is set up haggard-like to begin with ). It's made of CNC'd aluminum. I'm pretty sure you're also the only person in the world that has claimed the Supercharger bash of sucking.

    I have NEVER have my Gamut P20 drop a chain, either a 32 or a 34 tooth ring. Sounds like you need a washer on the top limiter. Talk to Scott. The derailleur issue sounds like a problem with SRAM or the derailleur hanger not gamut.

    The fact still comes down to its nearly impossible to drop a chain with a properly set up Gamut.

    I've had bad luck with e.13's. I was at a Giant Demo day here in the bay. Rode a bran new glory, I had to take it back to the tent 4 times and they still couldnt get the guide set up right. They even called e.13 to try and trouble shoot.

    I've installed a few gamuts, all you do it bolt them on and your set. Maybe put a washer on the top limiter thats it.

    i've had some problems in the past with a raceface guide and when i finally got tired of jamming the chain between the top guide and the bashring i decided to enclosure the chain in a homemade lg1 style. like this. Never had a problem again and it took me an hour to do it.
    i'll never use another kind of guide.

    Nothing is fail-proof. That's a fact. The blanket statement that "if it fails it's set up wrong" is a shortsighted cop-out for poor design.

    There is a couple mm of gap along the top guide, but when the chain is being yanked against it from being derailled over the bottom roller, it flexes, and a gap opens up. It is set up the exact same way that brand new Demo 8's are set up with the same guide. ALSO, the chain is the correct length and has no problem cycling through the travel without the shock in the frame (when the chain is actually on the guide and able to move). Trust me, I take my time and set up my stuff damn well. I can take pictures later to substantiate this.

    The derailleur issue comes from being ripped off upon bottom out from there not being any slack in the chain due to, guess what, a locked up chainguide. Also note that the Gamuts have non-adjustable height on the upper guide, only side-to-side spacing. The upper guide also isn't the issue here. It derails over the rather large gap between the bash and the lower roller, THEN gets yanked out of the upper guide when the chain is off the ring and pulling towards the inside. The lip on the rollers just aren't tall enough (yes, I have a new one on there). That is just a design flaw.

    So looked over the damage on the bike a bit closer. It is going to cost me: new derailleur, new hanger, new rear wheel build and maybe a rim, chain, and possibly the cassette. I'm planning on going for the MRP guide unless Gamut can do something about the poor guide design and the blown up back end. To be honest, I'm just expecting to have to shell out a few hundred to get the bike usable again. The bike industry just doesn't have the margins to be able to fix collateral damage like the auto industry can (example: Thule fixing damage to the rest of YOUR car when THEIR retaining devices fail).

    The Gamut has been fine up until this point and I think the backplate is just able to flex too much after having the chain yanked out of it a few too many times due to the worn roller before. If a worn guide is that catastrophic and they can't alter their design to be more durable then I think I'm going on to one of the new MRP's.

    Anyone have a spare X9 or WTB Dual Duty 32h????

    I have the same problem with my gamut. I lost the chain twice on one run this morning. The gamut is good idea but the backplate has too much flex because they tried to make it too light and the rollers arent adjustable up and down so when things wear there is a gap that the chain can pop out.

    Machine your own, my chainstay kept dropping chains so i did a little modding and bent it to fit right. Haven't dropped a chain since.

    That sucks that the mrp won't fit. Maybe grind down the part thats in the way? I've had mine for 2 years, bolted it on and haven't had a single problem since day 1. Not 1 dropped chain

    I meant that the "sandwich style MRP's would not fit. Meaning the ones where there's a full circle backplate. I wasn't even aware that they had boomerang plated ones now that didn't require the backplate.

    which for all intents and purposes the exact same guide. They use the same back plate, they utilize the exact samd color coded washers to space the plate, and the spacing is the exact same. The ONLY difference is that the srs uses the bash as the outer plate of the top guide, where as the LG1 uses an enclosed upper guide that does not need the guide to limit cahin freedom.


    TO the O/P if you are breaking e-13 bashes, you are not following proper set up. Tight chainring bolts will spider crack the poly, and many petro chemicals will attack it (loctite, petolium distilates)...As for the chain comming off the top, or getting behind the chainring....again another set-up issue, sorry, but it is.

    Boomerang's alone without the second full circumference backplate I meant. I was only aware of the "sandwich" style ones and another one that had a 3/4 circumference backplate that was just too horrible to install/align, but that thing was way oldschool.

    I haven't been breaking E13 bashes. I never had any problems with hairlining the chaingring bolt areas? I was mashing the edges of it so it would interfere with the chain and chainring, ie really fatass flat spots on it. Result was having to pull it and dremel off the lip that came from the flat spot and replace a chain because it wore into it.

    Again, chains coming off the top is a wear/durbility issue for these types of guides (vs dual plate). I know how to set up a wheel and a pulley...


    What's funny is that now that I mention this to people, I'm starting to hear all kinds of the same thing about Gamuts dropping the chains over the lower roller in similar fashion. Weird.

    How much space between you lower roller on your Gamut? There shouldn't be much there. I do not have any problems dropping chains on mine, been running Gamuts for a couple seasons now. But, you need to space the boomerang out correctly, and adjust the roller outboard. There should not be much room there.

    On the upper guide on my Gamut, I adjust it outboard until it rubs a little in the large rear cogs then grind off a little bit of the guide until the fit is exact.

    I ride a lot of really rocky terrain where your bike really gets to bouncing around and I have zero chain drop issues. But, when I got my first Gamut and didn't take the setup to these lengths, I did have a couple issues where the chain came off.

    hope this helps.

    Got a picture of what the gap looked like? My Gamut is making weird noises as of lately. I hope this doesn't happen on the trail to me.

    I'm running the MRP G2

    I like that it is a taco design that protects the bottom roller. Upper cage is very adjustable up and down and in and out with washers. Also, as little drag as I have ever experienced in a guide. It is working very well so far but only have this season to date on it.
    Before that, was using the sandwich style plates with the two roller boomerangs. Worked well with iscg but not so much on a bike without as they would rotate on me. Before that, a DRS that kinda worked but would drop to lower ring on me on the rough stuff. Better than completely but not doing its job completely if you ask me.

    Look into the MRP G2, my favorite so far.

    normally I wouldn't comment on something that "sounds" obvious .... but you sound like a bit of a hack.

    - regularly throwing your chain, causing major costly damage, using a guide that hundreds (thousands?) of other riders use without any issues? Try letting somebody else install your next guide. It can't hurt and maybe you'll find you've been doing something wrong.

    - regularly smacking your bashguard so hard that you have to file "fatass flat spots" off in order to remain useable? Finesse: it's not just a shampoo anymore.

    With the e.13 it just sounds like you need to space your backplate out a tad more.

    As far as the gamut goes, again just sounds like you need to space it correctly. There's not a whole lot of flex going on in the system.


    Either way, there are thousands of people using these things (including me) who have used both guides for years without a single problem. Calling the design poor doesn't really fly. You're in the minority. If the design were at fault, that wouldn't be the case.

    "Smooth" is not a word that is commonly used to describe my riding (although about half the rocks that hit my guide are just loose rocks that get kicked up off the front wheel, not from casing stuff). I usually try to ride my stuff pretty hard, and build it so I can do just that. I do, however, take very good care of my stuff mechanically. AND I have had two other people set up the guide after it had dropped chains. It STILL will drop it. What's funny is that I have heard from quite a few other people over the last couple days about this with Gamut guides that drop the chain off to the inside through rough sections when properly set up (yes, actually properly set up).

    As for the flex, you'd be very surprised, and you'd also be surprised just how much leverage can be put on the chain that translates into lateral force against the backplate when it's derailled when the suspension takes a hit or when you put your weight into the end of the cranks. It ends up being a lot more force than you could humanly exert against the guide directly, so don't expect it to flex as much if you were to just put it on an edge with both hands on the ends and pushing down.

    Err - how much space between my lower roller and what? The chainring? In what gear? The flaw here is that you have to have the thing backed off just enough for the chain not to want to "climb" over the roller as you're pedalling in first gear, but at that point there's enough room for it to get yanked off. I usually dial it in a bit from there to close the gap and deal with the drag so it would appear that there is no gap for the chain to escape through. Again, lip isn't tall enough.

    As one of my buddies said today about his P40, "when they say P40 I think they mean 40t only" since his 36t ring had been dropping (I run a 38t).

    Dude, if nothing on the market is working for you...make your own

    Never had my e-13 srs fail except for once when it was set-up wrong when I got a smaller bashguard

    If you're riding as hard as you say, everything is going to break no matter what you do to it, so just ride stuff till it breaks


    Maybe some trails-style bashguards might help..those are extremely strong, but heavy

    Thats the main fault in gamuts design, the rollers arent adjustable up and down like mrp or e13 to accomodate different size chainrings. Thats why I run a p30 witch is designed for a 36t max witch is the chainring I run. Even then i still drop the chain fairly easily and its gotten alot worse when I switched from sram back to shimano saint so the chainis flying all over the place through the rocks.

    going to agree with that^. how the **** are rocks , mind you "loose" rocks flying up and bashing flatspots into your guide?, you either no longer need to ride or learn how to ride cuz your problem seems like not a manufacturer problem but an individual problem

    and p.s. use MRP, they rock

    LOL. Where you from (probably east coast)? ever ridden with DHIdiot? He's no hack. Well, if he's a hack, then I should just stop riding. Trails here are rocky, and your bike gets destroyed, fact.

    hey gordon, have you checked the boomerang yet? I just checked mine and the damn thing is bent, The upper part of the boomerang is only bent maybe a mm or 2 but the lower portion is bent at least a few mm's witch is easily enough to let the chain jump off. The thing is the boomerang has never been hit on anything and it was bent inward so it had to have been done by the chain. I'm going to see if i can find a piece of 1/4 plate aluminum and cut a new boomerang with less cutouts so it will be stiffer.

    You made a good choice IMO. Chainguides are in one of the worst places on a bike for damage. I'm trying an LG1 right now after running Gamut's for the last 2 seasons. The LG1 came on my new bike though, so I'm giving it a shot.

    DHidiot: Sounds like you need this:

    You coming up to northstar anytime soon?

    I would be happy to set up either one of your guides for a six pack.


    I've seen plenty of people have problems with gamuts. I've never seen one of those same people have it spaced correctly. I think that might be the problem. "setup correctly" means not providing it with any space for a chain to fit through. Smooth or not, when someone the size of Curtis Keene can run one and not have problems, you should be able to as well. Big guys who hit shlt hard will experience just as much flex as you.

    Don't go by what a manual says, go by what you SEE for spacing.

    I'll admit, they can be a pain in the ass to setup but it's possible.

    If I get my bike back together I'll be going up there next weekend I hope!!! No thanks to this bullsh*t though. The guide will be off the bike, taken up into the hills, and blasted to hell with a shotgun by that point though, but thanks anyway.

    I don't doubt that James' is bent. The problem with the backplate is not that it flexes but it starts flexing way way easier once it's been hit. It's skimpy to save weight and it compromises easy. Oh well.

    I've been mulling over making my own but it's not going to be ghetto. I gotta find the machine time/tooling to do it and I don't want to pay to have a backplate CNC'd. I already know exactly what I'm going to do with it.

    Of course, all this time I've just been wondering what it would take to make a properly tensioned SS DH bike, but I'm far too lazy to spend the huge amount of time necessary to screw around with gearing until I get it right.

    And to whoever was claiming that rocks flying up and hitting the underside of the bike is indicative of not knowing how to ride, you clearly have not tried drifting through loose lava rock corners at a fast pace. It'll tear you and your bike apart if you arent prepared for it.

    im not saying rocks flying up means you dont know how to ride im saying that a rock flying up and creating a flatspot in your bashgaurd is rediculous, then again your right i have not drifted through loose lava rock corners at a fast pace.

    that is what I am saying....the boomerang alone with a crescent has been around for a long time.....it just the other ones were so popular

    TO the O/P if you are breaking e-13 bashes, you are not following proper set up. Tight chainring bolts will spider crack the poly, and many petro chemicals will attack it (loctite, petolium distilates)...As for the chain comming off the top, or getting behind the chainring....again another set-up issue, sorry, but it is.
    Half of it is the same. The upper idler makes a bigger, more secure difference in the case of the LG1. The SRS merely uses the bashguard to sandwich the chain to a wear plate and the bashguard. The LG1 idler makes it utterly impossible to lose the chain up top seeing as it is enclosed 100%.

    So...with that said its pretty different compared to the SRS. The lower roller is basically the same though.

    While I'm on topic I'm not really fan of chainguides that use bashguards to wedge the chain in to keep it secure. There's too much room for failure...dirt, debris, spacing issues etc. However, this is only in theory and I am sure when properly setup its fine.

    Here's an idea Gordon: Go Chainless. My friend did it today at Northstar. Rode most stuff fine. Might want to have a buddy to tow you into trails.

    No seriously...I think only you can choose which guide you see fit.

    I basically did and was able to rally the last half of the trail with the good steep stuff. It was fun.

    Going chainsless at a resort with chairlifts is easy, I did it last year when I ripped my derailer in half an northstar. But most of the socal trails require pedaling or are alot more fun if you pedal so chainless really isn't an option.

    It seems like the chainring is too large for the chainguide making the chain too close to it's exit. The Gamut guides are designed to have only one size ring. The e13 guides don't work with a bash too small or a ring that is to big and neither will work without the maximum spacers behind the back plate. A bit of rub in the beginning is good and the chain will machine itself a nice little home and then you are set.
    If you are having so many issues then just run a Gamut and a Taco like Minaar.

    I wanted to make a note of this too. The guys at Gamut have been good to me in the past and much more helpful than the E13 people were. I received a PM with an offer to help with the guide personally from Mateo, which is good of him despite all the Gamut bashing here (though I did make a point not to go into anything about their service as it has been excellent historically).. I'm still going to try the MRP guide if I come across it cheap but it is not for lack of Gamut's CS. If the product is flawed their consumer relations are not. If they refine the product a bit I will be back on their guides.
