MRP Responds To SRAM XX1 With Three New Chainguides - Eurobike 2012

Aug 31, 2012
by Richard Cunningham  
SRAM's announcement that its new XX1 one-by-eleven drivetrain needs no chainguide reverberated through the industry. A bold statement, perhaps, but early test rides on the single-chainring transmission seem to validate that claim. To MRP, one of the world's premier chainguide makers, that news must have been unsettling. Single-ring drivetrains are their core business. MRP's response, however, was quite positive. They developed the AMG - with a simple upper guide that positively ensures the chain will feed onto the drive sprocket and with a sturdy bash guard below to protect your investment from bottom-outs and rock-hits. The MRP Micro is a full-function chainguide designed to work with the smaller chainrings made possible by SRAM's ten-tooth cassette cog. The Micro can handle sprockets between 28 and 32 teeth.

Two for the Trail

MRP amg chainguide

MRP's AMG chainguide adds the security of a top guide to a single-ring AM/Trail setup and the protection of a real bash guard. The advantages are light weight and a very silent running guide system. MSRP is $99.95 usd.

With 29er and Enduro riders joining up with traditional DH and XC single-ring devotees, the market for chainguides is not going away, but rider demographics are shifting more towards AM and trail riding - a trend which suggests lighter weight, and simpler guides will be the go-tos for most new riders. The Micro and AMG are definitely targeted at those folks, but MRP also cranked out a new guide for the Big Bike set as well.

MRP Micro Chainguide

The Micro chainguide is the ticket for riders who run small chainrings. The compact system looks proportional when paired with smaller sprockets. MRP's Micro should prove popular with 29er riders as the larger wheels require smaller chairings to achieve similar gearing as a 26-inch wheel model. Expect to pay around $150.

MRP G3 bash is removable

MRP's Micro bash is removable should you want to clean up the bike's look or drop some grams.

And One for Gravity Riders

The G3 Chainguide has two features, long in coming for chainguide users, The traditional boomerang has been scrapped in favor of a lower profile flange arrangement and the bash guard has been integrated into the lower roller guide. The integrated lower piece hinges on the mounting flange so that the chain need not be broken to thread it around the chainring and through the guide assembly. The upper guide splits and unhinges to facilitate this acton up top. MRP calls the feature "Swingset" and it simplifies the guide's assembly process and makes it possible retrofit the guide to an existing drivetrain without breaking the chain. Another addition is a soft plastic bushing at the tail end of the top guide that quiets the chain.

MRP G3 2013 chainguide with swingset integrated bash guard

MRP G3 chainguide with its Swingset integrated bash guard will replace the G2 SL guide. Its compact backing plate is slightly lighter weight and, like all MRP guides, the adjustable mounting hardware is fixed to the guide plate so the bits won't jump off and run away when you are adjusting or assembling the mech. The G3 retails for $150 usd.

MRP G3 Chainguide

Loosen all four mounting screws and then remove two to swing the MRP G3 chainguide elements open. The chain can then be easily threaded around the front sprocket without breaking a link.

MRP G3 G-Slide plastic guide

MRP G3 is shipped with a slippery plastic insert that replaces the roller guide pulley. The "G-Slide' plastic guide is intended to keep the chain running smoothly when the terrain is muddy and sticky.

 That's a decent MSRP for MRP
  • 19 6
 Lost faith in MRP when my G2 SL broke first ride last year. Not even sure how to this day. Inferior brittle plastic that does not take impacts at all. Just recently put on the straightline silent guide and loving it. No mechanical parts to fail and find myself looking to see if my chain is still there because it is so quite and smooth. My 2 cents.

 I'm confident that the G3 solves any issue you've had with the previous generation product - and every G3 guide includes the G-slide slider block so you can choose what style you like to run (pulley or slider). Cheers

 just hit them up a guarantee you they will warranty it. i have had nothing but good luck with their customer service.

 Yea I always tried to stay away from mrp because i dint like the way it looks cause im ignorant but when ever i ended up with one on my bike i was super stoked on the quality MRP is great bang for buck! I choose mrp over any other brand any day!

 awesome idea with the g-slide option. love the smooth lines of the G3 as well. well done.

 @Adam81 I have to agree, the plastics on my MRP Mini G2 SL would break if you looked at it the wrong way.

 They fixed that issue with a glass filled nylon molding instead of plastic now. no more issues.

 Fully off topic here but anyone else notice the lack of chainring spider on the cranks? Just noticed.

 ^Glad you said that. I looked at the crank and thought, that someting did not look right.

@ adam: Got one myself, best chaainguide ever

 Those are MRP's bling rings. They bolt directly to certain SRAM cranks with removable spiders. Let's you use small 28t chain rings and looks cool too.

 If you have plastic parts mysteriously dying it might be wise to consult the tech documents available online. By accident I came across the one at E13 regarding which chain lubes are safe, and which ones will make the plastic stuff crack.

 The bash guard snapped off my MRP G2 after less that 10 rides. Brittle indeed
  • 8 2
 Hope they're stronger than the G2sl!

Because mine broke just where the bashguard stops sitting over the aluminum, and now that won't even be fixed over the aluminum.
So it still can break at that point, maybe even faster cause it's with a hinge... In that case the hard plastic pulleywheel cover (which was another weak point on the SL) in one piece, doesn't change anything.

 I witnessed the poor strenght of the SL. 2 broke in one week. another friend had one too but was cracked

 My G2 got the bashguard pushed into the chainring at the last race. The only sign of impact was a 1-2 millimeter dent in the guard.

 I got kinda put off MRP with the last set of cranks I got from them , the ' cambers' yeah I know they are catalogue cranks but they could at least pick a descent catalogue cranks to put thier name on. Mine flex like crazy and i'm only average wieght at most , the pedal inserts have come loose and the BB is of the lowest quality I have used ...

 Does anyone know if the Micro will work with a VPP suspension? I've been trying to find one that doesn't contact the huge lower VPP link without success. The AMG could work with a clutch derailleur, but I still prefer the security from an actual chain guide. Hopefully the Micro will accommodate it.

 Is it me, or does the first pic of the G3 show a G3 with a carbon backplate??? :O

 I was @ the eurobike and visitit MRP .
i recommend the G3 chainguide it is realy nice and very solid ! also the slider is a nice feature
and huge thanks to the guy from MRP who take time to answer all the questions (thumbs up)

 bike parts in general are only making 100-150% profits MAX and that's some amazing cost cutting engineering. most times its in the 25%-100%.

I bet you'd be way more bummed on the price jumps for apparel. Sew a few pieces together and add velcro or weave magic fiber together and engineer it to not fail and then glue it up and ship it out.

 Im having so many headaches with this guide Frown
Im on to my second taco/roller in 6 months after both failed and cracked at the bolt. The thread strips on the included hardware making it extremely difficult to do up with any tension at all, also, its hard to "swing" closed with ANY trail debris in the gap near the roller end, the holes will simply not line up. Idea is great, but in practice, you have failed pretty bad MRP. Stop trying to make it too cute and too light, just make it work!! I will hapily take a 100 gram hit for something that WILL LAST FOR YEARS. Now, go make it.

 I thought mrp and truvativ/SRAM were working together :s or was that just for a one off chain guide? Which seems to be a waste of time now truvativ are pushing products that don't need chain guides...
  • 3 1
 I thought you didn't need a guide for XX1 because of the indexed chain and chainring?
  • 3 3
 I can't see any way that you wouldn't need a chain guide. Yeah, a clutch rear mech maybe negates the need for a bottom roller (still rather have one on a DH rig for security), but like I say, I can't see how the XX1 drivetrain gets rid of the need for a top guide.

 The pictured 1X set up is not xx1.
  • 2 0
 Sam264 I agree with you on that and SRAM openly admits that some riders will find a guide necessary with XX1. I personally will add that weight and be absolutely confident I'm not going to drop a chain.
  • 3 1
 xx1 uses a specially designed chainring, and the rear der. works very differently than a standard one. you don't need a guide.
  • 3 0
 Have you used XX1?
  • 2 0
 the xx1's hooked and crosshead chainring teeth combined with a special chain are supposed to keep the chain on
it can be yours for $1G+
  • 1 0
 it's mostly the protection of the bash guard that you want. Big teeth on the XX1 chainring should avoidthe need of guide
  • 1 0
 I think for now I'll stick to a normal setup with a guide, maybe when this stuff comes down in price in a few years I might give it a try, I'm still skeptical though!
  • 1 1
 I've got a single ring setup with a clutch mech derailleur and you still need a guide at the top. Tried it without and dropped my chain 3 times on one lap of half nelson.
  • 1 0
 Even SRAMs Pro riders are using a guide with XX1 on rough courses. Once again they openly admit some riders Will Still Need A Guide with XX1. The ring design really helps but doesn't eleminate the need for a guide. For those of us who ride rough and rocky terrain at high speed.

 You people clearly don't understand how much it cost to manufacture this these days. Take your current guide down to your local Machine Shop and ask them how much they would charge you to make 1. Most shops will give you a weird look and say alot more than you can afford. I was quoted any where from 250-1000 dollars. And that's just for the machined parts. As long I had a 3D CAD Drawing and written the Program for the CNC machine.
The plastic parts ranged in price from 20-35 dollars each. Plus $2800.00 dollars for each mold and $2500.00 for engineering and programming for each peice. Then the distributor and the shop need to make a few bucks as well. They aren't making as much as you all think. Granted these are prices from American companies not from Asia, but MRP makes their products in Colorado less than 2 hours drive from where I live.
  • 2 2
 ^ HAHAHA If you're ever lucky enough to work in a shop take a look at "cost" of these parts and then tell me that they aren't making as much as I think...
  • 4 4
 Bikethrasher, your commentary is valid only for 1-off custom guards made by a machine shop. Production run costs are nothing at all close to what you're yammering on about. Production runs will spread the costs across a full run.

What you are talking about is the cost of a prototype design worked to conclusion as a 1-off full custom. Obviously since MRP has been in the game of guides for 20 years (or whatever, seems like 20 yrs), prototyping and 1-off are not as expensive for them as they would be for a full-custom at a machine shop that doesn't ever make chainguides.

When trying to sound authoritative on the Internet, it helps to be fair-minded and even-handed, and not act as the fluffer for your bros.

 MRP still had to pay for their shop. Machines and qualified people to run them. CNC machines Start at 100k and get into the millions really fast. Engineers and CAD Programers aren't cheap to employ either. MRP also has to pay for the many prototypes that need to be made to produce the final product you see. Those costs are passed onto the customer as reflected in the cost of the product. Once again this is a product Made IN America. Not Asia. We actually have to pay our workers a competitive wage and provide safe working conditions. Unlike most of the rest of the world.

My Quote for the plastic parts is for a production run of 1000 units. At 20 - 30 dollars per part to produce. MRP does this in house so that cost would be less be maybe as much as half. The machined parts cost is based on the same quantity.
I designed a guide and looked into having is made and quickly found there isn't much room for profit. Unless I had it produced overseas. Which I dodn't want to do.
My prototype top guide with a clamp mount weighs just over 35grams. Direct mount guides were as light as 10grams. I made these for my Trail/ Enduro bikes and one for a friends BMC hardtail.

 Production runs in the bike industry are nowhere near as large as they are in other manufacturing industries. It's not as easy to have huge profit margins when the production batch you're doing is in the 5-10,000 range vs. other industries who'll do batches in the 100,000's.

 Bikethrasher if you are serious about your guide get some more quotes , your getting it up the rear on some of your costs , i have a buddy who does molds and such and ya they are expensive to build parts are cheap once it,s all said and done . and a company like MRP probable uses SOLIDWORKS or the likes and can do the whole part and test fit it all right on the screen with out turning a machine on if the guy using the program too the fullest , i would bet they might even have a rapid prototyper that can produce the parts based of a dxf file out of plastic and test fit them as well without tieing up a cnc machine or a programmers time , the whole part can be designed and produced without making any chips or leaving ones desk for that matter .

 Demon666 Thanks for the info. I have a small mill and have been making prototypes in my garage. Milling the parts from blocks of Aluminum and Plastic. This really cut down prototype costs to next to nothing aside from my time. My design is Definately different from what's out there now and it's lighter I just need more test time to make sure it works as well if not better than what's out there now. I'm hoping to have a guide ready by spring. In the end I have to be sure I can make a profit to make all the financial risk worth it.

 i designed and built several versions many many yrs back when MRP 1st came out with their original design , i borrowed one that a buddy used for a season and beefed up the design and ran 2 versions on 2 different bikes that where free rode lots and raced and both ran flawless , problem i had was $$$ and local guys already in the biz that would borrow ideas and start pumping out design that undercut others , the MTB biz is cutthroat at times LOL
