    MRP System 3 and SB-3 compatibilty problem with Saint and SLX cranks

    Why is the System 3 and SB-3 with the guide ring not recommended for the newer Saint and SLX cranksets, according the MRP website? Is it due to the different spider? Or are there any interference on the guide ring and the crankarm itself?

    I am looking at them as a high-quality replacement for my battered chainguide but I don't like the extra weight of a Party Crasher bashguard, for compatibility's sake.

    Will there be the same problem if I decided to use the E13's SRS or SS+ guide?

    I kinda like the old-school look of the System 3/SB-3, but the G2 is almost 2x the price of the LG1 here, which is very strange.

    I think it has to do with the spider.
    For the record I didn't have any trouble fitting an E13 guard to my SLX, but fitting the SLX guard on hussefelts required a little bit of filing on the guard.

    The issue with Saint/SLX are that the crank tabs are ~5mm thick versus ~3.5mm thick for most normal cranksets. Of course, the additional thickness is designed for strength but it severely limits your bashguard choices. The additional gap between the edge of the chainring and the bashguard can be enough to wedge the chain in there theoretically.

    An LG1 style system doesn't use the edge of the bashguard as part of the retention system, and is therefore the better choice if you want a chainguide.

    I should also mention that the stock Shimano bashguard (36T) used the same outer diameter as our Turbocharger bashguard...it may be possible to use them together, however I havn't tried.

    My buddy uses the DRS, and he is now using the Shimano bashguard from the SLX. His only problem was with the bolts, which he had to purchase at the LBS.

    and Mr. Phil, is the SS+ and the SRS almost identical?

    Not theoretically, the chain does get wedged between the ring and the guard on both the SRS and the Gamut when used with their accompanying bash guards.

    Dimensionally identical. I would still recommend an LG1+/LS1+ if possible.
