I put this on my sons MTB. He dropped a chain twice during a race, so I put this on and have have ZERO drops or issues. The guide hasn't moved at all. I put sharpie marks on the adjustment bolts to see if the guide would move during heavy mtb use, and it hasn't moved at all. Very impressed for the price.

This chain guide looked like exactly what I needed after converting my bike to a 1x drivetrain by removing the front derailleur and middle chainring. The part installed easily and fit well. It worked perfectly (no dropped chains) as well, until it broke. The problem is it broke after just 20 miles or so. If you can't afford to be spending $32 every 20 miles, I recommend looking elsewhere.I have tried to contact the seller after my chain guide broke, and they have not responded. It has been over a week since I contacted them.TL;DR: this chain guide would get 5-stars if it was durable, but it irreparably broke almost immediately. Cheap quality and poor customer service earned it a single star.

This little tiny piece is my lifesaver. I converted my XC/Trail 2x to 1x with same crankset, I dropped my chain many times. Now I put this chain guide, I never experience any drop chains! The quality is good! I recommend this chain guide. It's worth it!

I'm a mechanic and have no problem with working on my bike. However it takes quite a bit of adjusting to get it right with my 1x8 gear system. Then there is the problem of the adjustment bolts x3, are made of very soft metal and strip easily. There are no spacers for adjustment of the width of the guide. I hope the exchange goes smoothly. I really want this to work.

This install on my Marin Gestalt x10 gravel bike in 5 minutes. Very easy to install and although I haven’t had a chance to ride with it yet, it had all the necessary adjustments to dial in in. No more dips in the road or bumps are going to throw the chain at 30+ mph. If the chain does still come off I’ll update this review.Updated 04/16/2020:After about 10 rides, I've pushed the bike hard and cannot get the chain to jump off. It just WORKS!!! I love it. Well done. I've flown down hill at 40mph and the chain stays put....

This chain guide works great. Easy to fit to my bike. Works exactly as expected and easy to adjust over the chain. 5/7 would recommend.

I can't believe something so small is almost 30$ I'm think it's a rip off but it did fix my chain from popping off the chainring. And I guess that makes the price ok. It's not plastic, it's a nice metal material and seems sturdy. I noticed my chain would try to pop off and this guide just pushed it right back on the chainring and I was able to continue riding and not have to get off my bike and put the chain back on.

Soooo, it didn't fit. BUT! But I drilled into the frame and mounted it just above the swingarm. I knew more or less that my trek fuel ex6(?) due to its design, wouldn't accommodate this piece. However, as the picture shows, a long bolt and a small hole later, and this guy is working great!The basic design is sound, the chain keeper portion, the halfmoon plastic, is perfectly shaped to guide the chain back on the cog. I ha e torture tested by on trail sections that always dropped my chain off, and had zero(0) none, nada, zip chain drops. I jump, land, slide, rattle, jar, and shimmy, and when I pedal again, the chain is always where it belongs.Thanks!

This is a thoughtfully designed chain guide that should work for many kinds of bike. It's not quite right for mine, however, I still managed to make it work by using the outer edge of the guide to the left of the chainring, and so far this has prevented any incidences of the chain coming off the drivetrain (which happened on a daily basis before, no matter what I did). The reason this does not work as well as it could have for my bike is because the chainring has an existing guard to the outside, so the guide can't fit over the chain.

Overall I like this, it does what it is supposed to do. I have an e-bike with a single 42t ring on the front and was having a dropped chain problem. A dropped chain is not only frustrating but can be dangerous so I knew something needed to be done. Some time ago I had the same issue with a different bike and put a Paul Components chain keeper on that bike. The Paul is definitely the better piece of gear, with much nicer machining and made completely of a nice alloy. It has however become MUCH more expensive than when I bought it and I just did not want to pay $45 for a tiny bit of metal that is just going to get gunked up. I thought the Origin8 was worth trying at a much lower price and I am satisfied. This one is easier to mount than the Paul, although the 31.8 clamp was slightly too big for my 31.8 seat tube (I solved the issue by doing a couple of wraps with silicone tape and mounting the clamp over that).Helpful Tip - remove the end bolt that holds the chain guide section together and pull the front section of the chain guide off. That allows you to see where the chain is for positioning purposes. Once you get it positioned where you want it tighten all the bolts on the clamp section then reassemble the chain guide section.I've had this on my bike for 2 weeks now and no chain drops so it appears to have solved the problem. So here is my summary of this vs. the Paul :Ease of mounting definitely goes to the Origin8. Being able to open the chain guide section and see where the chain is in relation to the guide is a huge benefit. The Paul is all enclosed and frustrating to try to get it positioned by feel only - hard to know exactly where the chain is. The Origin8 has only one bolt with a "swing open" clamp so that is also easier when tightening things up. The Paul is a clamp with 2 bolts so as you tighten them one side ends up pulling the alignment out so you have to keep re-positioning constantly as you go.Overall quality and feeling of workmanship - hands down to the Paul. The Origin8 feels cheap by comparison. That is why I am giving it 4 stars.To summarize, if the 2 were the same price I would buy the Paul since it is so much nicer quality. However, mounting the Paul is much more trouble and ultimately the goal is just keeping your chain on the ring, right? Both do an equally effective job for that purpose and for the most part you forget they are there after they are mounted. At this point if I ever have to do it again I would probably opt for the Origin8 since it is a lot easier to mount, holds the chain on the ring as it should and saves me $20 to boot. If I ever have problems with this I'll update it but right now both chain keepers are doing the job they are supposed to do.
