Building my new M3 and tried putting on a MRP System 2 with Azonic 454 Cranks. . . it's NOT going to work. Perhaps with heavy modifications, but not worth trying.

I know a System 3 with Saints will work, and I'm assuming it still took some customizing (i.e. get out the Dremel) of the MRP boomerang.

What have you Ridemonkeys been running into? What's working and not working? What kind of customizing have you had to do?

Do tell . . . please!?!?

ive tried the stock SRS and it wont work without trimming one of the reinforcing ridges on the lower part of the guide. also i do not think a 44t ring will work, maybe not even a 42t, im waiting for a fork to build that bike up and ill post my complete findings.
ive been in touch with e13 on the matter and they are studying the possibility of making a custom m3 boomerang like they did with the gemini dh, im sure they'll chime in soon.

id really like to hear what sort of problems you have had with the system 2 as thats the guide intense always pictures the m3 with though.

Odd that they have made a bike that dosent fit with the chain guides....thought that problem was a thing of the past.

yea its pretty weird, i could understand how the e13 didnt fit right away as intense always has worked closely with mrp, and with the m3 being a vpp design that historically has been cluttered in the area to the rear of the bb, but a system2 not fitting is weird, i cant really see why.

I am using MRP System 3 with Saint. The setup was very easy. A friend of mine is using E-13 with Saint. To mount that it took at least 3 hours, but I've seen on the E-13 website they have an adapter for M1 that maybe works for M3.

It all depends on what length BB spindle and rear end spacing you use on the M3

If you use a 113 spindle and 135 rear end, then the upper reinforcement ridge on an SRS back plate will need to be ground. I have a part here that has been ground to fit actually. Also a small bit of the top edge must be ground to clear the upright.

With the 128 / 150 spacing, none of the reinforcement rib needs to be ground, and only about 3mm of the top corner of the boomeranng needs to be filed off for extra clearance. The mod takes about 30 seconds. I can ask Jonas to maek a template for you guys to use. I think most riders would prefer for DH anyways becuase of the wider hub flange spacing and the fact that the chainline moves away from the tire.

Hope this helps

Jonas actually has worked pretty hard to prepare some instructions on the M3 fitup. With the 128 spindle and 150 rea hub, modification should not take more than a minute. I'll make sure that template gets put on the e.thirteen site ASAP.

The guide on the M3 that Intense uses in their pictures (and on online) is a standard System 3.

The problem that I am having with the System 2 . . . oh, I was trying the BB mount version . . . . .is namely is that the “blocks” (the area that houses the tiny set screws) on the back side of the inner plate/boomerang will not allow the plate to sit flush with the Bottom Bracket shell. An ISCG mount may work better, as would require a lot less trimming, I just don't have one right now to try. I will be calling shops today.

It seems that what’s going to make most chainguides work w/ the M3 is by using a bottom bracket that uses the external bearings, like the Saint. With that bottom bracket, and a little Dremel work, most chainguides will probably work . . . . . I ASSUME?!?!

Dave. would you happen to know if my e13 SRS is gonna fit my 05 v10?
The website only mentions instructions for the 03/04 v10.

Thnx, Kevin

The SRS ships as OE equipment on all 05 V10 complete bikes. Fits up like a charm.

Luna Chix rocked them all 04.

Kay thnx man, I was a little concerned from what vitox said about the VPP.

Keep in mind that the V10 has a 150mm rear hub, and was designed to use a 128 BB spindle. Running narrower cranks is not recommended.

Ok Im running Holzfeller cranks so thats no prob. but I was planning on using the 118mm GigaPipe BB from my previous DH rig. hadnt really chekked if it would fit yet cause Im not really into the technical stuff. Guess Ill order a 128mm then.
Thanks again man!

Pbody - with the M3 you will have best fit results with ISCG set-ups. We designed the System 3 around Slalom and WC sizes, allowing for the same boomerang to be used for both sizes. However, this means that you do need to cut a bit of material off the top of the boomerang to not interfere with the swingarm. You can use the System 2, but it will require a little more modification.

We will be producing a smaller boomerang, in the future, specifically for this application as there are very few frame designs with this issue. The other solution is to space the boomerang out at the ISCG tabs and widen the bb spindle length, however this is usually not recommended as it may result in less than optimal chain line which will make you unhappy down the road.

Call us direct at 800-999-8277 with any questions.

What up dogs?
BB spindle lengths are going to be a factor here. A 135 rear end will require a 118 spindle with our guide (even if they recommend a 113). The 150 rear end will require a 128 spindle for correct chainline (55mm). I've heard, but don't quote me, that the Diabolus and Saint cranks will be coming in longer spindle lengths shortly (and they may already be out by this posting). On the SRS you'll have to shave down a little of the upper rear corner of the top of the of the backplate so it clears the seat stay upright (pic). In all of the cases you have to shave down some of the lower inner wearplate so it doesn't get in the way of the chainstay (pic). To get the reinforcement spine (on the back side of the backplate) to clear the lower linkage you'll have to take it down with a dremel tool or bench grinder (the area of concern is in an attached pic). If you need to use more than 3 spacers between the backplate and the ISCG tabs (128 spindle and 150 rear end) then you don't need to modify the spine, just the upper rear corner of the top of the of the backplate. This leaves the best possible set up of the Standard SRS backplate. The rotation is not ideal, though. With the Gemini backplate we experience the same spine issues, but you don't have to worry about the upper rear corner of the top of the of the backplate. Your Standard SRS's will work with the proper mods, but I would suggest using a bashguard one size larger than you normally would and then using the bottom bolt hole on the upper wearplate due to the extra sag designed into the VPP suspension. This bottom hole in the upper wearplate is usually only reserved for 10"+ travel bikes.
We'll keep working on this issue as these frames should be pretty popular. If parts of this don't make sense or you have additional set up questions please feel free to let me know. support@e13components.com
