yeah and it has the option for a lexan bash w/ al inside. i dunno seems pretty cool. id try one out.
ps: skiings for pansys

I'll be getting one shortly, cant wait. As for the MRP Fusion Ring (their lexan/al ring) should be available before the end of the month. If you want an exact weight figure I'll try and get one for you tomorrow.
Lopes raced with that chain device from End of july till now...have not had any problems with it...he even was running it without an outer plate for a bit, till I just was over looking at it like that. Works fine, never weighed, but I think it would be a pinch heavier than old. Easy to install and adjust-pretty much idiot proof.
How does it look on the inside when it comes to bolts sticking out like the old MRPs ?
Not trying to hate, but just a little info: the tabs where the bolts hold the ring to the spider are the places where the bashrings feel the most force. Having worked with polycarb bashrings for FOUR YEARS now, we've learned a few things about them, and there's a reason why we use such thick mounting tabs and custom hardware.lovebunny said:
Also, as DW has mentioned numerous times, there's a lot more to developing a useaeble polycarbonate bashring than just injecting some "lexan". If you get a chance, get a few different brands and give them the 'finger nail test' - flick them with your index finger and see which one feels the least brittle and like it absorbs impact the best. Then do the 'wall test' - chuck each one at a wall and see what survives.
We had a big customer of ours do this, and it was no surprise to us that they were ready to order more afterwards.Anyway, like I said, I'm not trying to be a hater - I'm just trying to give some objective facts here.
Have fun,

I'm running that version of the MRP at the moment. I think it's meant to be lighter than the System 1 version with the double plates.
Anyway it's been great, I picked it up late last in the summer so got maybe 6 or 7 days on it doing hard DH runs. It's a breeze to set up and so far no problems. Looks good too, though I'd prefer black rollers.
I don't have the lexan bashguard incidentally.

That would make sense. How the hell would it be heavier than the old system? Looks like it could be cheaper, too. The most complex part about the old one was the mounting system and all the required machining (with the fixed inner plate). Now its a simple outer plate and a couple of plastic blocks. Looks nice.jon-boy said:
Bit I'll stick with e13. Now that the (now former?) best-known chain guide maker has validated what e13 has been doing for years, I'm sticking with the product made in my back yard.
exept for we dont know what their bashguard is made of or how well it will work yet...John P. said:
Well, we do know several things:zedro said:exept for we dont know what their bashguard is made of or how well it will work yet...
1) there is no engineering polymer available or advertized that has the impact and tensile strength requirements that a bashguard needs that can cross link (stick) to metal. Not one.
2) the highest amount of force in the bashguard is at the attachment point (the tabs)
3) polycarbonate is the only CLEAR engineering thermoplastic that could even remotely be considered as a bashguard material.
Conclusion you ask?
I dont think its any mystery what the plastic material genre is. Obviously its not the Tuffmax alloy that the Supercharger uses, but it is almost definitely some sort of polycarbonate.
Well, theres that, and the fact that the marketing material actually says LEXAN ....
But who really knows, right?
Dave
Maybe it's glass .......you guys ever think of that? Jeez. It would be cool to watch it blow up when you hit a rock.
So I've seen the elevator shoes that have voids filled with water and little fishies......maybe we could to that with a bashguard? Anyone?
And a sidenote: who WOULDN'T love a job where it's your duty to throw competitor's products against a cinderblock wall as hard as you can?
edit: a much better idea: we've all seen those concentric rims that rotate freely from the hub on cars/trucks, how about a bashguard that spins freely from the fixed tabs?. You might actually accelerate off of the downside of trees and rocks.

actually, the picture was of an independent group of industry crazy men who happened to send us their findings. The picture I think was sort of a joke, but damn funny.
I dont know if I personally want a bashguard thats more slippery than what the Supercharger is already though, it already slides pretty good. I like your thinking though!
Melding a couple of your ideas, how about a bashguard with a fish in it??!

Kevin trying to talk to some guy in da' hood: "I see that you have some very nice aluminum coincentric rims on your cadillac escalade sport utility vehicle, they are of a 26 inch diameter, and look absoultly smashing"stoney98 said:
well we all know how peeps hate assumptions here....dw said:
1)yes it's been mentioned and most likely the two materials are mechanically constrained rather than chemically bonded. However you are assuming that this wont work which i think isnt quite fair until we actually know.
2)thats why they went with aluminum at that point, while achieving a thinner anchor point. I'm running one of the original Evil Superchargers, and i've noticed theres a slight change in the tab area/inner dia design
Also seeing as they arent on the market yet, there could possibly be design changes. When i thought about this type of arrangement, i envisioned the Al plate being completly covered by a plastic matrix if you will.
Maybe you'll be right and the mechanical interaction between the two materials will cause them to fail, but I'd rather see the product out on the market to find out. Then you can say "i told you so"....
I guess thats the benefit of having already tested such an arrangement. I dont have to hypothesize. As stated previously, one of the main reasons befhind the development of the supercharger was to increase impact capability of the guard.zedro said:Maybe you'll be right and the mechanical interaction between the two materials will cause them to fail, but I'd rather see the product out on the market to find out. Then you can say "i told you so"....
Anyways, my real point in writnig to you before wasn't at all to discuss the virtues of the design. We will all see how it goes on our own.
My reason was to say "Hey Zedro, the mrp marketing material calls the material used LEXAN" (you had suggested that it might not be previously)
Thats all!

I know dog, my steez is hella wack.Curb Hucker said:
Anyone who know if the new MRP3 system will fit on Karpiel bikes. It has always been a problem to fit the Sys1 and 2 due to the bolts sticking out in the back of the plates.
seismic said:
You know the countersink, chainring bolt and washer trick right?
i though MRPs came with countersunk bolts? when i buy their replacement pulleys, it alsways comes with one CS and one button headkidwoo said:
That's not what I'm talking about. If you have a karpiel, the highest rod that adjusts the inner plate on the boomerang interferes with one of the linkages on a system 2. You have to take it off, cut off the machined piece the rod goes through with the set screw and drill out the hole to fit a crank bolt. For a smooth surface you need to countersink the crankbolt on the side facing the frame.zedro said:
Better get something else...but what ???
The system 3 may work on a Karp,There are a couple of very small button head bolts on the back side,but i believe that the way you adjust the space between the chain and the back plate is with washers.As long as your bb is long enough and you are using 1 or 2 washers to space it towards the chain i think the backplate bolts will be flush so nothing hits the link.
We will have one here on monday so i can check it out.
Looks good otherwise.

Looking into it closer it appears that they are all ISCG.and you have to buy a BB to iscg adapter for BB mount frames(like the Karp). This adapter alone should space it out enough to make the small button heads on the backside flush.
Looks like a light,effective guide.The upper roller could help mud roll through.The E 13 obvously works great and is the most durable,but mud can get jammed into the upper block.Maybe the MRP will be better in this area.Van Dine brought his bike back from Europe and i was pulling the mud out of every nook of the guide and everywhere else,he never made mention of any problems though so maybe there isn't a problem.It just appears to be a potential issue to me.
Also i find it funny that MRP want all black but they still are sportin the orange rollers.I'm sure it's the marketing aspect of the orange but they should understand by now that more DH bro bras would buy em if they were all black! The black pulleys are for sale though.just add $20 to the cost of the guide.
I dunno what MSRP is and we have to stick to it,so i'm guessing we will be selling them for $149 with a free chainring,so the price has come down and is competetive with the e 13.

So you would recommend the MRP 3 over the E13 for muddy EU conditions when riding an Army ??? (live in cold and muddy Denmark)

$20?!I bought a package of two orange rollers for $6 at the Mt. Snow nationals last year in the MRP tent. When I rolled by on a bike with an Evil guide, no less
How can they possibly charge $20 for a couple plastic rollers?
Actually, the SRS is pretty awesome as far as mud clearing goes. The minimal contact between the upper slider and chain allows the mud to clear out pretty easily. Its ability to clear mud so well is one of the features that has made it so popular with the mechanics and riders on the circuit. Thats still no substitute for cleaning your guide out every couple practice runs on a super muddy day though!

Does the E13 works with the Karpiel links ?
I wouldn't reccomend the new MRP to anyone till i mount one and test it!seismic said:
Well i looked it up,looks like you got hooked at the race,we sell em for 9$each,but that's with 2 bearings and the axle.They might sell just the rubber roller for less.binary visions said:

Ok...waiting for your review then !
Well, let me first say hello to this board, I have been watching for quite some time but havent thought it wise to pipe in at all, being the Sales and Marketing Manager of Eko Sport, Inc, the owners and manufacturers of MRP, Im obviously biased in my opinion. Secondly, let me say that I think highly of our competition, and apologize if I ever write anything that may be construed as offensive; its never my intent, as it doesnt serve a purpose.
For those that want to know, the new System 3 is in fact a lighter weight guide with additional options from the System 1 and 2. Off the shelf it fits a wider range of frames, yet it retains the same quiet, smooth retention that the original systems share. We developed the System 3 over a year ago and then tested it for 8 months before releasing it to the public it won the World Cup overall with Steve Peat, Red Bull Rampage with Kyle Straight and a number of other World Cup and NORBA competitions during its testing phase, and has stood up to numerous other high intensity real world stunts. Those results came after we were satisfied with initial in house/controlled testing. I feel confident in saying that it stands up to any other chain guide on the market, including our own.
Oh, and sorry I didnt look you up directly, but whoever was trying asking about the System 3 fit with a Karpiel, no problem. Use the ISCG adapter and bolt it right on.
The System 3 is available in three different offerings standard with a 5mm aluminum bash ring, with the new Fusion Ring, and with a carbon fiber boomerang and guide ring for the ultimate in light weight retention. The System 3 Carbon is not designed for bashing; it is designed for 4X racing and dual slalom.
Regarding the new Fusion Ring. We use a proprietary polycarbonate blend; Lexanâ is a registered trademark, as well as a different blend nowhere do we state that we use Lexanâ, but we do state in our literature, for all to see, that we use a polycarbonate material in conjunction with an aluminum inner ring. DW is correct in stating that polycarbonate will not directly adhere to metal, aluminum in the case of our ring, so there is obviously a lot more going on than just injecting an off-the-shelf polycarbonate that would explain why the Fusion Ring is patent pending.
The Fusion Ring was designed to withstand abuse from all directions. Like all polycarbonate blends, no matter what the brand name is, it will scratch and slowly chip away with repeated abuse. The Fusion Ring will not delaminate, nor are you likely to break the tabs off at the chainring bolts. The Fusion Ring will work as an outer ring for all MRP Systems and is available with a 4-bolt, 104mm bolt circle diameter and best accommodates chainrings of 34T-40T. The Fusion Ring gives you the best properties of polycarbonate blended with the desired strength of aluminum at the attachment points.
I cant speak on the construction of non MRP rings, I can only comment that the Fusion Ring is a product derived from listening to what abusive riders all over the world have asked for. We have a goal as a company to develop cutting edge products using the best materials for the intended use.
Sorry for such a lengthy reply, and I hope I didnt sound too marketing or company driven, but remember, that is part of my job. So you all know too, since it does matter to many of you, I do ride MTBs bike (all types); I have ridden seriously for 23 years now starting in VT, where I grew up, and all over the world. My backyard now consists of Fruita (where I actually live), Moab, and Crested Butte, so never hesitate to ask about our products and how they relate youre your particular region and conditions, I can relate.
Thanks for your time,
Jason

for the record, it was a BRICK wall.kidwoo said:
The System 3 with the stock fatty ring is 415 grams and for the System 3 with the fusion ring it's 465 grams.

So here is the triggi part...I am running a Saint crank, so is it still possible to use the ISCG adapter and run the MRP 3 system ???JBT said:
No, this was a package with two rollers, bearings for each roller, and all the associated harware. Well, score for me I guess - I just rolled up and asked the guy the price of extra rollers. He said, "We only sell them in packages of two. $6."leprechaun said:
Jason, welcome to the Monkey - it's always great to hear information directly from the source!
Hi Jason,JBT said:
I think it would be awesome if you could clarify the above point I cut out here.
It seems by what you are saying that you have a thermoplastic alloy that you say can cross-link chemically to metal, and maintain the cross link to the yeild stress levels of the thermoplastic.
I must be misunderstanding what you are saying, am I?
I am sure that I dont need to tell you that all of the major plastics manufacturers have unsuccessfully been trying to structurally cross-link engineering thermoplastics and metals, and maintain the cross link to the yeild stress levels of the thermoplastic since the advent of injection molding. Chemically it should be impossible with a polycarbonate blend but you never know really. This is the reason that almost all high stress multi-direcitonal inserts used in injection molded parts use some sort of mechanical interaction to distribute stress between the plastic and metal parts. From what has been shown of the fusion bashring, it seems that this is the case.
Can you clarify?
Welcome on board, and see you at the races!
