Is there a more frustrating situation than being mid-race and losing a chain over a particularly rooty and rutted section of downhill track? We think not, unless you have a bet with your riding buddies. When seconds are on the line, chain security is what matters. E Thirteen knows this well, and they have the answer. The SRS+ Chainguide is designed for single chainring use and will keep a short leash on a flopping chain and protect the chainring teeth no matter if you are riding downhill, freeride, park, or dirt jumping.The E Thirteen SRS+ Chainguide takes a traditional approach to chain security, although it has some very well crafted improvements over older designs. It uses an aluminum backing plate to hang the upper wearplate as well as the lower wearplate and Tech 3 Stealth Idler pulley. The Tech 3 Idler runs smoothly and quietly even with multi-gear cassettes in the back. It uses their Turbocharger bashguard which is designed to flex and absorb impact stress, sparing the brunt of the force from your crank and bottom bracket. The idler pulley is fixed to a bolt-on lower portion of the mount which can be set in one of three angle positions dependant on the requirements of the chainstay design or frame geometry. Gold anodized alloy hardware is used throughout to add some bling and spare a few extra grams.The SRS+ is ISCG '05 compatible and comes with an adapter plate for mounting it onto frames with no tabs on the bottom bracket shell. It's available in white or black in two versions -- one for 36/32T chainrings and one for 40/36T chainrings. The E Thirteen SRS+ Chainguide is proudly made in the USA. 195 grams.
Strengths: -It works. Never has dropped a chain while riding.
-Haven't been able to clog it with mud.
-Pretty simple installation and adjustment.
-Looks pretty good.
-Set and forget.
Weaknesses: -Chain rubs pretty good on both upper and lower wear plates depending on selected gear. More on this below.
-Had a good bash on the guard and it bent one of the crank tabs ever so slightly. Bit of a bummer.
Works well, a bit pricey. The chain rub really isn't an issue. I suspect it's because I'm running the guide with a BB-ISCG adapter. I didn't have to use the included washers. Good product, would buy again.
So, I looked all over the web....sent Bikeman.com an email but I can't seem to find an answer.
Has anyone bought one of their e.13 SRS/Evil "blowout" chain guides?
Bikeman doesn't specify the mounting options though they are kind enough to say "no returns," and "make sure it works on your bike be ... Read More »
Can you put a bigger chainring than the chainguide is design for?
In my case I have a 32t e.thirteen chainguide but I want to put a bigger chainring. I can see that there is some more room (millimetres) in there to put a 33t or even a 34t chainring considering that between a 3 ... Read More »
i have an E.Thirteen SRS with the new ISCG 05 Standard ready to mount , but my Giant Faith has only the old ISCG Standard.
My Question is, if it is possible to mount it with an ISCG 05 adapter.
I've heard that some people have tried this and it caused some problems.

just installed an e.thirteen srs chainguide, and everything looks OK.
i have a 38t up front, and an 11-34 XT cassette on the back mated to a giant STP frame. problem is that the STP has a short chainstay, and when the back is on the 34t, the chain rubs against the pully on the chainguide.
