    Strengths:    Stylish,
    You can buy different colour bash-rings
    Improved pedal feedback.
    No chain drop, unless your gears aren't indexed properly
    You can run different size chain rings


    Weaknesses:    Altho mine was free, You'll have to shell out £110 ish
    Adds weight
    Can come loose If not fitted properly
    A real pain to refit chain
    The roller stopped roling and has mow all but disolved


    Bottom Line:   
    I was advised to get a Chameleon, as it was the perfect bike for me, as I'm 18 stone plus and ride with little or no finess. I got a deal at mud-dock to replace the raceface crank with a Hone E13 DRS combo.
    I'd seen this device in some bike mags attached to the hone crank and thought, that it looked bad ass.
    I havn't been disappointed, my chain stays on, what ever I do, It looks good, and in improves, shifting and acceleration.
    If you have trouble, fitting it any good bike shop will do it for you.
    (all I need now is a fork that works)

    Strengths:    - Reduce chain slap
    - Very quiet
    - Enhance pedal feedback
    - For dual ring setup
    - Resist chain drop as well
    - Adjustable for different chain ring size


    Weaknesses:    - Crappy installation guide
    - A little expensive


    Bottom Line:   
    Get this if you wanna run dual chain ring system. It does secure the chain from chain drop and it is very quiet. It reduce the chain slap as well when doing the descend. So i would say it do what it suppose to do and it does give more then what you can expect.

    Strengths:    Outstanding functionality. It does precisely what it is designed to do.

    Weaknesses:    A bit complex in its design. The instructions packaged with the guide, SUCK. They provide a combo of b/w pictures and drawings. The parts aren't numbered so you can't match the part picture with the corresponding description...a critical detail that can save you some headaches when dealing with small screws.

    Bottom Line:   
    While this guide can be tricky to assemble, anyone with decent mechanical aptitude can do it. The guide works, period. Never dropped a chain, never had issues with the roller not rotating or bearings going out. Bashguard can take it all. I contacted e-13 about their instructions, and they agreed they need a revision, but it seems they've done nothing about it. Come on, these guys can't take some office poge and have him rewrite a more comprehensive set of instructions?? Buy it, you won't regret it. Anyone having problems with this guide, didn't install it properly.

    Strengths:    This is a follow up review. After runnignh the DRS on some pretty hard DH its help up great ...havnt lost a chain yet...silent..works great Best dual ring guide ever...seriously

    Weaknesses:    only one that I found so far was that E13 has updated and changed their hardware that comes along with the DRS and havnt changed the instructions. SAo when you put on the slider Plates(spacers) the short screws that they say to use arent long enough to reach the nyloc part but no big deal...just use long ones provided and it works fine and doesnt do any harm wgatso ever(not just me saying this I e-mailed E13 and they said the exact same thing)

    Bottom Line:   
    Absolutly GREAT product...Neverhad any trouble with it whatso ever

    I'd recomend this product over all other dual ring guides out there. Its worth the extra cash to get this one

    Strengths:    Well built, sturdy

    Weaknesses:    Heavy, expensive, poor roller design.

    Bottom Line:   
    I have used this guide for a year and had to replace the roller twice and the bearing once. Maybe the BC winters aren't the best place for it. The bearing seizes very easily being so small and the roller tends to gum up and stop rolling often. I don't feel that regular maintenance should require disassembling it after each ride. I had a Blackspire Dewlie that ran flawlessly for 2 years without hassle. I now run a Blackspire Stinger. It's the best $30 I've ever spent. Just pick up a lightweight bashguard of your choice to run with it and you've got a great setup for under $60.

    Strengths:    chain rolls perfect, solid, clears mud well, not too many moving parts

    Weaknesses:    directions are great if you are a bike mech. need more pics!

    Bottom Line:   
    First chain guide so we will see, so far so good. Directions need some more pics and the web could use some more to. Was losing my chain every drop bigger than two feet. Have not lost it since. Recommend if you don't work on your own bike alot have it installed by a pro. Good for the money so far and sheds mud well.

    Strengths:    chain stays on and bash guard works well

    Weaknesses:    my roller dosent roll but I guess it was designed that way.
    Maybe the weight


    Bottom Line:   
    It works rally well but the path had problems putting it on so I brought it to the bike company. It looks as though the bike co just went with a bigger bash guard to make it work but I'm not sure. Before I had this puppy installed the chain was comming off like crazy through the rough stuff. Now my chain never comes off even when back spinning.

    Strengths:    This is a follow-up review, see below.

    Bottom Line:   
    This is a follow up review. In the last review, I had pulled the guide of my old AC2 and put it on the Faith, and was getting a lot of chain suck. Finally diagnosed the problem. I had the flip-flop roller mounted backwards (ie. large section of the roller away from the bb instead of closer to the bb). Duh...., pretty stupid mistake. Now the guide is running absolutely beautiful.

    Strengths:    Keeps the chain on the rings when pedalling forward.

    Weaknesses:    I do experience a fair bit of "chain-suck" when backpedalling. I've toyed around, and noticed that when backpedalling, the chain will slip off the large side of the roller to the small side, causing the chain to come off the big ring and jam in the derailleur. I'm not certain it's a problem with the product though. I think if I play around with the chainline some more, or the spacers on the chainguide plate, I might be able to get it to work better. Also, installation is a bit of a pain, and the bolts don't fit very well into the plastic plates, making insertion/removal of the bolts a nuisance.

    Bottom Line:   
    The product is decent, but like I've said, I think there may be a lot of tinkering required to get it running real smoothly. While pedalling forward it's fine, but the chain suck is a pain when you're stopped on the trail, and trying to get your cranks lined up flat before getting on your pedals and dropping in.

    Holds the chain exactly how its supposed 2, still shifts smoothly. Since i have gotten it i have about 8 crashes on it and it hasent dropped the chain once, works awesome. Wich i woulda gotten it with the black bash instead on the clear but o well. Makes a slight brr sound when peadling but hardly noticable, and doesnt bother me at all

    Strengths:    Keeps the chain on the ring despite any crashes.

    Weaknesses:    The weight? But who really cares

    Bottom Line:   
    If you are a rider that like to climb and then decend, this product is the only one for you. It shifts perfectly, it hold the chain no matter what, the bash guard will take just about any abuse you can throw at it. Any one who says that E thirteen makes crap, is not mechanically inclined or did not read the entire instruction sheet. The instructions definately say to NOT USE MINERAL BASED LUBES. Some people never read instructions. Install is very easy if you have ANY mechanical ability. Plastic bash guard WILL crack if you over tighten the chain ring bolts. FOLLOW THE INSTRUCTIONS and nothing will ever go wrong with the product. I personally promise you. I'm sorry for those of you that paid full price, Ebay baby, Ebay...

    Strengths:    Well designed. Operates as promised.

    Weaknesses:    Bearings make a slight brrrrr sound when pedaling. Bearing should come packed with Waterproof grease. I peeled the seals and repacked with Phil's after a wet ride washed all the lube out.

    Bottom Line:   
    This is a nice addition. Quality design and craftsmanship. It required a little machining to get around the suspension components on my Reign, but in the end I am very pleased with the results. Because I didn't buy it new it has a higher value rating that I would give for list price.

    Strengths:    Never drops the chain.
    Two rings are better than one!


    Weaknesses:    A fairly pricey upgrade - but worth it.
    Installation can make your head hurt. Take it to your LBS


    Bottom Line:   
    It works - it shifts - it's quiet, and one season of abuse and so far very durable.

    Only time it hasn't shifted is when it piles up with mud and forest floor debris. Clean it out quickly and all good again.

    And yes, I remember seeing the warning in the box about mineral spirits affecting the plastic, (and that was early spring of this year.)

    Bottom line - so nice to have a small ring at times, and with no problems with this guide - why doesn't everyone (non racer - non weight weenie) run two rings?

    Strengths:    None

    Weaknesses:    Cracks like crazy

    Bottom Line:   
    I bought this bike about 2 months ago and absolutely love it, the problem is this darn E.thirteen DRS guide system and bashguard that was put on it for the dual ring set up I have. Bottom line is it stinks, first my bash guard started to crack around the area where the bolts are, then the chain guide roller brack cracked, then the bracket that the guide roller bolts to cracks. Dang! I'm mad, I called the bike shop and told them about my bash ring and promply put a race face bash ring on, then I started to notice the other parts and found out from them that you can't use a chain oil like Pro Link that is a mineral oil. The instructions say nothing about only using certain chain oils, but I called E.thirteen and they confirmed what my bikeshop told me. I love this bike, but I'm really dissapointed that I have to start tearing it apart and looking for a different set up now after all these problems. E.thirteen said they'd replace the roller and the mounting bracket, but I'm still suspicious if it's going to hold up. I read a lot of positive reviews about this product, but I'm having a hard time believing that I'm the only person that hasn't used Prolink on this system and had problems. Maybe I'm just the unlucky person who got instructions that left out the warning not to use Prolink or I should have somehow known that only certain chain lubes won't make these plastic parts brittle, Bottom line, I'm very irritated
