    I'm looking at chainguides and can't decide wether I should get a dual ring system or single. I'm into downhill and freeriding, but I still want to be able to pedal up hills. I'm mainly worried that a dual ring system won't work as well on the downhill runs. I don't really have any experience with chain guides, so all info./help is welcome. thanks :help: :o:

    I run an Evil DRS on my VP-Free with a 22-36 combo and will never run a single ring system again. I actually climb *gasp!* :).

    hehe, I've ridden Whistler 6 days or so this summer on my ASX with NO chainguide and have no real issues as long as I descend on the bigger ring. On the granny gear I'd drop it when it got rough but then I just kept it in the above. I will be joining the dual ring chainguide crew one of these days.

    Point is, they just keep your chain from falling off on the inside...no less reliability there between Dual and Single guides

    I run an Evil DRS on my Demo 9 with a 22-38 combo and 11-34 cogs shifting by SRAM. This is the same setup I had on my Big Hit and I have had absolutly zero problems. :thumb: :thumb:

    I run double up front and adjust my high limit screw to just barely shift over enough to where I NEVER have it jump down to the granny gear or, worse, my bb shell.
    I still climb, yet I freeride and DH.

    Aren't I special?:drool:

    this is good info! have any of you had experiences racing with the guides you use? i'm at the end of my first season and just can't decide. i'm leaning towards a dual system now.

    SINGLE RING!!!!!!!!!!...........for racing...go single...you dont want to have to worry about your chain falling off AT ALL when racing. If you are free riding, or hitting whistler or just messing around go with a dual ring, but if you plan to race, definetly go with a single ring...in the end it will be safer, and you wont have the thought in the back of your mind of your chain dropping coming into a berm at 30 mph in the middle of your run. :thumb:

    Amy (Snacks) had no guide at her first race at Mt. Hood and keept dropping the chain to the granny.
    She bought a DRS and I don't think she has dropped it since? And it never dropped completey I don't think, just down to the granny.

    If your building pure race bike then single, but if you are doing any sort of dual duty then you'd be better off with a dual ring.

    BTW, I was running a Blackspire Dewlie dual ring setup on my Demo and don't remember having any issues. I am running an SRS now as I m primarily racing it but this fall will probably put the Dewlie back on. Or if I can find a DRS for cheap (and there are no application issues) I'll get that.

    Some good points above. If the bike is for racing only go single. If you plan on doing anything that would make your bike dual duty go with a double, both the Black Spire Dewlie and the E13 (Evil) DRS are reliable and easy to set up. I have raced with my DRS and used my bike at Whistler and for general trailin for almost 3 years now and have never dropped a chain. In fact I have never had any problems with mine, ever. So my chain just doesn't come off, :thumb: now if I could just get me to stay on the bike........ :think: :mumble: :mumble: I would be ok. :evil:

    Now that I am thinking about it, with the Blackspire guide if I pedaled backwards too much it would down to the granny??? Not sure if this had anything to do with the 150mm rear spacing or not?
    I don't think it ever fell from just riding though.

    The E-13 DRS allows you to back pedal with no gear change. At least it has never change on me so it has functioned completely as designed and advertised. If I had to chose I would go with the E-13 DRS. Something to be considered is frame compatability. Check the mfg web sites to make sure if the guide you choos fits your frame. Sometimes the guides need mods to get them on some frames.

    the prob w/dual guides is that typically they have to be run with smaller rings... the DRS can be run with up to a 40, and most rings up to 38 are flat and don't shift well)... (I just changed out a 40/26 DRS to the 40 SRs)... I'm building an new bike... it will be more pedally... I'm gonna run 38/28 ramped and pinned and on my old bike I'm gonna run a 40 and when I get the time to switch it a 44... the new bike is a Uzzi Vpx the old bike is a Banshee Sceam... I figure the Scream will be more for Shuttling and Chairlifts while the Vpx will be more freeride and pedally...

    I dunno Bob, I seem to remember a time I asked you about not running a single ring guide.......:D

    Was it Chelan? or Winthrop? I can't remember. Maybe you were jsut running a bash guard.......

    Just a bash gaurd and 2 ring setup then and it was Chelan a couple of years ago. I almost never back pedal but in one corner at Chelan I always do and without a guide I dorped my chain to the outside. Since installing the DRS I have had zero problems.
