i have the bb mounting version, and whenever you hit rocks it rotates up. the boomerang also bent pretty severly when i was rolling over a 1 foot drop so now i'm debating what to do with it
well it does its job. mine bent so i dont know what to do. i'm thinking of sawing off the lower portion of the boomerang to keep it from hitting and bending because i dont think you need it.
its a good chainguide, kindof expensive if you buy new, that works well for DH just so long as you dont ever hit it on rocks because it will either rotate if its bb mounted or bend like mine did

The best design out there. I've checked out the new offerings from Truvativ and Race Face, found those models either too heavy (made os steal), too easy to break (plastic parts), and the boxes on the top-side of these systems serve as a handy crap collectors.
MRP System 2 is built solid and keeps the chain on 100% of the time without making a sound... what else can you ask for?

it's a chainguide and is works. there's nothing very special about it, it's basically just a couple of of pieces of milled sheet metal. way too expensive considering what you get. when you get it set up right it will work like a dream. don't buy one unless you can find it for cheap. if you're going to pay full price for a chainguide, get an e-thirteen instead.

Bottom Line:
This is a sick chain guide that looks cool, can hit rocks without bending, and the chain never falls off. I learned through having this chain guide that you dont need a top roller because the bottom one keeps the chain so tight that the chain will never come off the ring.

Bike Setup:

Bottom Line:
This chainguide kicks ass! After a year of torture and two DH bikes, this is one part that has proven itself time and time again. I have cased jumps that would have folded most chainrings but the MRP just has scratches to show for it. Urban assault is no problem either as I have also cased to concrete and the MRP actually took a chunk out of the loading dock that I landed on! At race speeds, I still have the pedal power I need to keep mobbin. The only problem I have encountered has been that the boomerang will stuff itself into the chainstay after several rides. This has happened on all bikes that I have installed it on. Overall 5 flammin chilis for a truly bombproof product!

Bottom Line:
I switched over to a MRP System Slalom 1 chainguide after switching my bike over to a single chainring set-up. The results were outstanding, as I have no more chaindrop, chainsuck, and less chainslap. The rollers are legendarly smooth and the whole set-up stays put even under the hardest DHG loads and hits. The Slalom 1 was the only one that would fit on my low chainstay Haro, and when set up properly, the whole outfit looks like it was meant to be on this particular bike. Just a good product that does its job!

Strengths:
Makes you look like a hardcore mountain biker, when working, works well.
Weaknesses:
Stops working somtimes. There are just little grug screws holding the inner ring AND the guide arms.... And so when you do actually use the bash guard, the whole thing just tilts, and you have to try to adjust it.. But if you have installed it properly (locktighted), then it is extremely difficult to fix that on the trail (at least without phucking the whole system up by twisting it around the bottom brack, digging a trench in your bottom bracket shell... Also, it's heavy, and over rated, for sure.
Similar Products Used:
Hussefelt II chainguide (which is comparable to an MRP, except without the bashrings ((keep in mind that the bashrings are actually a drawback from the mrp system)), except weighs less, and works better... The chain is trapped in the hussefelt system, it is not trapped in the mrp system. Also, the custom AC chainguide for the Giant ATX one
Bike Setup:
My planet X has the hussefelt II, my ellsworth dare has the MRP WC2
Bottom Line:
I think that people should think less about what brand is on their bike, and more about what will make their bike work better, and how far they can stretch their wallets. The mrp chainguide system was an impulse buy for me, in that I only bought it because I have seen it everywhere advertised as such a wonderful device.. Upon actually owning one, I almost want the janky ass noisy AC guide back... I think I will take this chainguide off, and throw it away.. Then I will buy a hussefelt chainguide system for my ellsworth so my bikes'll match... In looks and performance.... On a side note, the Hussefelt chainguide is wonderful.

I run a 9sp rear and the chain doesn't touch the guideplates in the smallest or largest rear cogs. My ONLY complaint is cost. Come on, someone is making a killing on the markup on these things!! With the perfect function I've had, however, I can't knock it an ounce.

Bottom Line:
I had to run the inner ring stationary on my Chameleon. Pretty basic mods to accomplish this. Just drill through the ring and the boomerang, notch the ring for the chainstay, and mount the ring to the boomerang with some nylox nuts and sst screws.
The setup worked great. Never lost the chain. Mainly freeride and dirt jumps. Raced with it a couple of times. I ran this guide for about 6 months and have no quams with putting another on my bike should the needs arrise. Good product.
Only time it bugged me was when my Race Face cranks bent. Then the stationary ring rubbed. If you mount as per the directions with both rings spinning this wouldn't be an issue.
I only give em 4 flamin on the value since this is one of the more pricey guides. My overall opinion of the guide is very high.

Similar Products Used:

Bike Setup:
Aeon - Isis
Bottom Line:
First impressions were fine. It was very quiet & looked like it would be easy to maintain due to simplicity of parts (i.e. there's not much that can go wrong with it). However, Problems soon started just a few miles down the trails. My bike developed an annoyong clicking/crunching sound whenever I was out of the saddle & putting my weight on the pedals. On closer inspection I found that the main body of the device had come loose & was moving around the bottom bracket. The way the device is attached to the frame is a joke. Two tiny grub screws seem to be the only thing stoping any movement & these simply brace against the bottom bracket area not really providing a very secure fit.
A friend who had the exact same device fitted at the same time as I did experienced similar problems after 10 minutes on the bike. Not really what you would expect from a pro peice of kit. In MPR's defence these problems turned out to be the result of the bottom bracket not being fully tightened when the device was being fitted.
I decided on the MPR chain device because it seems to be the main choice amongst pro riders but after the experiences I've had all I can think is that the riders (or their mechanics) must spend a lot of time arsing about keeping things running sweet.
On the plus side the problems I had with the chain jumping from the outer ring to the smaller rings when riding drops & jumps has obviuosly gone (along with the smaller rings of course!) & when the device is running properly it is very quiet.
