I purchased this after converting my bike from a 3X to 1X. The very next day I go off the sidewalk and the chain falls off. I saw this chain guide and it looked solid. It actually is pretty well made and the best part is, it comes with all the Hex Wrenches, so you don't even need to go digging around for them. Came with additional fittings for your tube size, no instructions, but the item description has plenty of pictures and it come almost fully assembled. Like I said, easy to install and I went out and tried it, chain did not fall off, so it really earned those 5 stars!!!

In appearance, it seemed like an elegant design; however, mechanically, the design uses a pin to set the guard's distance from the frame and as the sole support of the chain guard. The pin is hollow aluminum for a short section, and if one catches one's pants on the guard, the pin can be bent or straight sheered off. This failing guard never suffered any impact and failed after three months, the second time a pant leg caught on the guard.

First I just want to say this is a nice looking chain guide. It is a little ‘big’ but not too bad.Now the bad. This thing uses 3 different sizes of hex to make adjustments. It worked great at first but after a few rides it no longer prevented the chain from coming off. After making an adjustment, it appeared to be working again but only for a few rides. I went to adjust it again and when I removed the extension arms set screw, the threads came out with it. For some reason they machined the area where the set screw resides which leaves very little material for threads. I am going to try to tap it for a larger set screw but it failed rather quickly.

Chain on my DIY middrive ebike kept dropping off. Seemed like going over a certain stretch of "washboard" blacktop set off a frequency that would knock off the chain. I checked all the common issues, it might be that my 30-year-old derailleur just isn't the best for this application. I installed the chain guide and not one dropped chain since. The unit looks like billet aluminum to me, very well machined. Relatively easy to install if you have any mechanical inclination at all. The design is pretty good, and for the price it's well worth it.

After one too many times of one or both of the following it was time for a solution:1. Chain pops off to the inside while in the lowest gear2. Pant leg caught in chainThis chain guide looked to be the absolute PERFECT solution so I decided to give it a shot.Upon opening the box and checking the guide out it looked to be of high quality and VERY well madeUnfortunately when I tried to install it where it was designed to be, I was unable as it would contact the shock.Hmmm... I was just about to return it when I thought, "As much as I hate returning items, there must be some way I can make this work"I tried simply flipping it over so the mount was BEHIND the seat-post and adjust it as close as I could to make it work. However, with the actual guide so far 'behind' where it should be, the chain would contact the guide in both the lowest two and highest two gears.Ok, that won't work so let's give it one last shot before returning it.I had a 3/16" thick pice of super hard plastic laying around (can't remember what is was from... something I used on my modified Samurai 4x4?) and it already had two holes the same diameter as the original guide screws and 1-1/2" apart, which appeared to be the distance I needed to move the guide forward.And whada'ya know, it worked PERFECTLY!To be sure I took the bike out for a 16-mile ride over rough terrain (more off-trail than on) while using all 12 speeds (bike is a 1 x 12) and had no problem with either issue #1 or #2.So... with just a little bit of ingenuity and some 'scrap' material I made the guide the perfect solution.As high a quality as this guide is, IF it was more adjustable so it could be flipped over and still work I would give it a 5++ if not higher.But as it stands, I can only give it a 4.

It's a little ugly, but it works perfectly. I've got a Schwinn Axum and the stock drivetrain doesn't have a clutch, which means it was constantly dropping chains. It got so bad that I wrecked a cassette, and eventually I even snapped a chain and tweaked my derailleur. The bottom bracket on my bike doesn't have mounting available for a regular chain guide or bash guard, so I had to go with one like this that can be mounted directly to the lower seat tube. I installed it a couple of months ago, and haven't had one drop since.

It’s a great product, I updated my old Specialized mountain bike to a 1x. I just wanted to make sure the chain doesn’t jump off track. Easy to install, comes with spacers for thicker frames, and has the ability to adapt to mist if not all frames.
