We tame complexity when we can. But in our quest for simplicity, a 1x10 rarely works perfectly without the addition of a chain guide like this e*thirteen XCX Chain Guide. The truth is that the front derailleur does a noble job of keeping the chain in line over your chainrings as you pedal through rough sections of trail. When you get rid of it, you'll want a guide to take its place.The XCX Chain guide functions in the same way, though you set it up once and leave it alone. It's perfect for race bikes, or any other bikes for that matter that rely on a drivetrain consisting of a single chainring and a multi-speed cassette/rear derailleur. The plastic slider, or wearplate, acts to keep the chain from dropping off either side of the chainring, no matter how choppy the terrain. And just like the variety of front derailleur mounting options, e*thirteen builds the XCX Chain guide to fit just about anything. It's available with four mounting configurations. All options will accommodate chainrings from 32 to 42t and are available in Black.1) Bottom Bracket: A 7075 aluminum backing plate functions as the required spacer between your drive-side external bearing cup and the bottom bracket shell. This mount is a great option for carbon bikes with odd seat tube dimensions, or if you switch bikes every year. It will always fit as long as the bottom bracket is of the threaded external bearing type. This option works with a 49mm chainline.2) Direct Mount: This fits frames that use a Shimano high direct mount on the seat tube. This type includes wave washers to adjust the chainline from 50-53mm.3) E-Type: This fits frames that have a E-Type, or more appropriately a two-bolt low direct mount on the seat tube. This type includes wave washers to adjust the chainline from 50-53mm.4) Seat Tube High: This option clamps around the seat tube above the slider, with the same fit as a high clamp front derailleur. If you have a pressfit bottom bracket of some sort, this would work nicely.
the good -stiff, height adjustmet works great. weight was acurate
Weaknesses: too small width opening/not enough clearance- chain rubs when in high and low rear cog very tricky/time consuming to get dialed.
got this for 9 speed. after taking off my b.b. 20 times I got real good at it. the only way to adjust l and right is w the 3 provided very thin b.b. metal washer spacers) finally got it "dialed in- meaning it rubbed on both sides when in far reaches of gears in rear casset. Probably wouldnt have caused much friction butI dont like the sound of chain rub. IMO it is just to skinny of an opening for a 9 speed cassette. (skinnier than typical fron derailure) using a shimano 9 speed hg chain.

Strengths: Super stiff, made of a HARD resin, never droppeed the chain once, have seen the flexy MRP drop the chain multiple times, this guide is much better and much more reliable. I am so amazed at over a year of riding the guide it has left me trouble free and has never dropped my chain once, that is very impressive, NOT ONCE. I do not ride smooth little fire roads, I have taken this thing everywhere from the rockiest trails in California, downieville, annadel, lake tahoe.
Weaknesses: None, product has been flawless and always reliable.
the bottom line is this guide is LEGIT and it can be used from all mountian to cross country, not to mention the super light weight. This is the best guide out on the market.
Weaknesses: might have to switch to a non-mineral spirit chain lube since it will ruin the plastic guide
Works like a charm on SS or 1x setups! No losing the chain regardless of the bumps and chain movement. Super light too!
Check your chain lube though--mineral spirits will make your guide brittle and ruin it...

Strengths: Simplicity, Does its job and looks schaweeeet!
I looked at paul components, mrp but went with the e13 and couldn't be more pleased. Rode really hard and the chain never came off. If you looking for a clean, relatively inexpensive chain guide this is it!
