    New MRP AMg

    Just wondering if anyone is using this new guide from MRP in conjunction with a 1x10 set up and a clutch rear derailleur? If yes any thoughts?

    Thanks

    im using the AM guide on my 12' stumpy evo expert carbon w/ XO type 2 med. cage.....super quite thru rough!!!!! only issue for me is I cant seem to get chain line perfect so chain doesnt rub on the bottom skid plate in the top 2 gears of rear cass... tends not to be a prob when climbing rough hills cuz the susp. is saggin enough that the chain doesnt sit on the beveled part of the skid plate....all other cogs down from that...its silent as can be

    ^^ I rub a very very little bit on the upper guide with my 2 smallest gears that I could never adjust it out but I never notice it

    OK been for the first couple of rides with the MRP AMG and it really performs well
    Its light, quiet and just gets on with the job
    Felt great combined with the clutch mech on my local rocky DH.
    I have a tiny amount of rub in the lowest gear but does not hinder pedalling
    Looks the business in white too

    How do I paste a photo on here?

    Using two AMG setups, both with SRAM clutch rear mechs.

    Well, one is a Micro guide with the back roller part of the lower guide bit cut off, in effect making it an AMG.

    Works very well, is quiet, and I've had no issues with chain drop. I'd imagine the soon to come XX1 clone rings from some aftermarket companies will make things even better.

    I'm probably going for pretty much the same setup (32t with 11-36t and Zee mech), so please do report back. Well, I'll be using an old G2 micro with the lower roller removed and some of the backplate filed off - looks like this is essentially what the AMG is.

    EDIT: looks like I stopped scrolling ad the ad-break! Good to hear things work well and that my plan for a modified Micro will work.

    so is anyone having dropped chain issues with this setup?

    My lower pulley on my Lopes just crapped out and I'm thinking that if the type 2 can do a good job of keeping the chain on the ring, I might just cut off the guide's pulley mount altogether and run it as a top only guide.

    It won't work as well as you would hope, at least it didn't for me. I would add in a Race Face narrow wide ring and then it should be golden.

    what didn't work well for you exactly? I'm running an NSB direct mount that has yet to drop the chain, but i was using a Lopes chain guide. Last ride, i took the broken tension pulley off the bottom of the guide, and it seemed to work just fine as only a top guide. I understand the concept of the narrow-wide chainrings, but I guess I fail to see how it would help me more than running a top guide to keep things in place.

    I've been running the AMG with a normal single chainring and Zee clutch mech all summer on my AM bike in Chamonix (very rough) and have dropped one chain. I'm sold.

    Meanwhile a friend here has a narrow-wide chainring with an XT clutch mech and normal bash guard - he hasn't dropped a chain at all even with the clutch switched off. Take from that what you will.

    Not in my experience (see above). And from how my friend's setup has been working (see above, again), I'd say any two of clutch mech, top guide or thick/thin ring is plenty security for AM riding.

    That said, if you need to buy a new chainring anyway you might as well go thick/thin if you don't mind the extra cost.

    AMG works great. I've used it with a Zee clutch RD. I've just recently installed a narrow/wide chainring and taken off the AMG and still no chain drops. So far so good, but time will tell...

    Trying out a 30T narrow/wide as a 1x9 (11-34). Using a standard RD (SLX, long cage) and have dropped a few chains on high speed chatter, braking bump chunk. Could use losing another link, but before I jump into a pricey drivetrain upgrade (10-sp, clutch RD) I wanted to try a guide. Any suggestions for the 30T? (Stuck needing a BB mount) Would a top only suffice?

    Losing some links will help. Mrp 1x BB guide should work, but your chainline will be altered slightly. May or may not make a difference depending on your set up.

    I'm in the process of building up a new bike and wondered if anyone else had some input on running the AMg with a narrow-wide chainring and clutch derailleur. I've got an XT Shadow+ and a Wolf Tooth Components 30T chainring I'll be using. I'm thinking the XCG or AMg, but not sure what option is best. I'm not sure I'd need the top guide on the AMg but am worried the XCG will be "too big" since its spec'd to protect at 36T.

    I'd go AMg personally. The weight difference is negligible between the two and the upper guide isn't "hurting" anything. No added noise, drag, or anything else - just added insurance against a derailment. Cheers

    Try running the narrow-wide chainring before installing the chainguide to see if there is even a problem with chaindrop. It may be all you need. I've had zero drop since installing one. Keep in mind that some frame manufacturers won't warrant a frame when the ISCG mounts are used to attach a bash guard, assuming that's how you will attach it. Put a bash guard on the crank which is stronger. Hope this helps.

    My Bronson came spec'd with an ISCG mounted bash guard, so Santa Cruz must have changed their stance on them. I'm not concerned with chaindrop, I'm concerned with damaging my chainring. I've got Shimano XT M785 in 2x10 which means I'm limited in my options of a crank mounted bashguard.

    Good to hear. Best not to find out afterwards about the tabs. They must have put some more meat around them now.

    Also, I wasn't aware that the narrow-wide rings came in "shiftable/ramped" style now. Man, things change so fast.

    New MRP AMg

    AMG and XCG use the same bash taco, so same clearance. I have a carbon AMG Micro and it is way oversized, much bigger than it should be for 28-32. The plastic cracks if you look at it funny - I am careful on solvents and lube and still have issues. Just use a narrow wide and a BBG guard.

    Bummer, I was looking for an AMG-like guide but I don't want the taco to be much bigger than my 28t ring. I bet there's no chance to find what I'm after.

    I believe the bash taco on the smaller AMg is smaller than the XCG. Give mrp a call and they could tell you for sure. I've used an AMg for a solid year and smashed it plenty of times. No issues with plastic cracking or anything else. Works great.

    They don't, you're not missing anything. I was simply telling you what crankset I have which limits my options for a crank mounted bashguard.

    The current XCG and AMg use the same skid. In terms of ground clearance, the small AMg is offered in a smaller size than the smallest XCG by a hair. ISCG-05 tabs get in the way of making integrated skids much smaller.

    We've never had a durability issue with the skid we use on the AMg, XCG, 2x, and Micro guide (all the same part) and stand behind our warranty. The upper guides are now all made of Nylon and should be unfazed by solvents, degreasers, lubes, etc.

    The only fit issues I'm aware of (off the top of my head) are the Giant Reign (tabs are positioned oddly) and Yeti SB-95 (frame members protrude into upper guide area).

    Didn't fit on a tallboy C. You can still use it without the skid, just top guide. Works OK with NSB direct mount ring. If it doesn't have the right clearance for the guide (rubbing the chain), gently bend the aluminum and it will be perfect. Having said that, watch out, the aluminum is very soft and can easily be destroyed by slight hand torquing of the guide bolt. I think my next guide is E13. They are more trouble free in my experience.

    I'm running a Wolftooth 30T ring with XT plus on my hardtail with a crank-mounted bash guard and have dropped exactly zero chains in a year.

    I just dropped down to 1X on my SB95c with a 32t Wolftooth ring/XT plus RD and have still had no issues with chain drop. Because the XT 2x cranks don't allow for a crank-mounted bash, I've not currently got anything installed for protection. I am looking at the AMg as well. I'm pretty confident that I don't need the upper guide given my lack of chain drops with the same setup on my other bike, but also don't want to go the XCg route because of the mismatch in size. FWIW, you could cut off the upper guide if you don't want it or if it rubs - this is my plan (though I hate to spend $80 and then chop it up).

    One question I've got, in response to your question, is whether the AMg will work with a 104 BCD 30t ring (assuming this is the one you are running). I was also looking at the Blackspire TrailX, a similar taco/upper guide situation, and that one specifically states that it will not work with the 30t 104 BCD ring.

    Anyone got any experience with this? Also, Noah (ifr you are still reading) - any issues with the AMg on the 95c? I know you mentioned the 95 as an issue, but is the carbon frame any different in terms of fit?

    The issues with 30t chainrings on 104 BCD cranks come from the required inboard offset of those rings. I think installing one of these rings on a triple crank would give you a pretty narrow chain-line and cause rubbing on some guides. Installing one of these rings on a double crank however would give you a not-so-narrow chain-line - so I don't foresee it being an issue.

    As for AMg on the SB95c - I'm not sure. You could check yourself though. Take off your cranks and BB and see if any portion of the frame or swingarm protrudes past the face of the BB shell roughly 3.5" inches straight up (12 o'clock) from the center of the BB hole. Kinda a hard thing to explain, does that make sense?

    Looks like Noah answered the question we were both wondering. I had just looked at that Blackspire and saw it doesn't work with the 30T 104BCD so its nice to know the AMg will.
    I'm still conflicted because like you said, I don't think I'll need a upper guide and don't want the mismatched size of the XCG. Sounds like there's a market for a 28-32T XCG!
    If you're interested, Blackspire makes a crank mounted, 2x compatible bash, its called the Defender 104. I think I'll run into the same issue with mismatched size though, since the smallest they make is a 36T.

    One of the worthy upgrades for those 1x setups is a sram crank. It opens the door for many direct mount options, which don't have the clearance issues of 104BCD in smaller rings. Good chainline, that can also be an issue with guides. That's the only sram part on my bike now (which started its life as a full sram kit).

    Nice cranks too.

    I've thought about this several times but I'm trying to keep the overall cost down. I've got my eye on the Race Face Next SL crankset, but they're a bit pricey. Luckily my Hope BB can easily convert to GXP if I end up with a SRAM option.

    I'm running a non clutch rear d on a 9speed setup with a RF n/w-34t. My chain fell off everytime i went through the chatter, and the it is as short as I can make it, maybe even too short (it gets thoroughly tight if I'm in the biggest cog and my suspension fully cycles, which hopefully doesn't happen to often while climbing). I ended up putting the 1x direct mount on and have had zero issues thus far, for some reason it makes my bike look better than just the tiny ring.

    So is the consensus that you should run naked with a narrow wide ring? I'm going from a 32t ring and MRP guide with rollers. I'd like to diminish the wearing on the chain from using the biggest cog, should I go with something for the AMg or just ditch everything?
