Reviews
"This worked for my 1x10 setup with a bash guard."
"I modified an old 80s Stumpjumper into a a 1x9 commuter with modern derailer, but the chain kept popping off during upshifts."
"Works great, have not had any chain drops since installing this."
"Is does the job for the most part, I still dropped a chain and tho flexed enough to allow it to pop off and it was a nightmare getting back on."
"This part was to replace the original one on my son's mountain bike."
"Worked as described."
"does its job, one crash and i bent it but that is probably just because of the way i crashed."
"Unfortunately the inner plastic part of the guide broke off after only a few miles."

Reviews
"Unless you need the prettiest chain catcher solution.. this will more than do."
"However after switching the chain kept falling off on moderately bumpy downhill sections every time I rode the bike, which was especially annoying because the way the chain ring I have is designed made it difficult to pull the chain out too. I went on a short 3 mile ride today on a trail that's pretty bumpy and the chain did not fall off this time, even when I hit the downhill sections with some speed!"
"This jump chain stop fixed the problem perfectly, AND it has enough adjustment to keep the chain on the 2nd and even the 3rd ring."
"No matter how well adjusted the front derailleur is, I've had cases of the chain jumping off the small ring when going from the large to small."
"The strap that holds the N-Gear Jump Stop Chain Guide on the frame looks like plastic and was too short to reach around the seat stay, and allow the screw to reach through far enough to engage the nut."
"Pedalec conversion of my Trek 7 resulted in too many chain disrails."
"Bought this as an inexpensive solution to chain retention on a new 1x9 setup."
"As it currently is, getting the nut started in a tight situation with bolt that only sticks out with a little bit with a great deal of effort is frustrating."

Reviews
"For a bike that is chain guide comparable, the screws that come with this do not work."
"definitely took some expertise to install needing different bolts and creative positioning of washers."
"Prior to installation I was dropping chains left and right."
"Still doesn't come with the right screws even though the info says 'Updated'."
"Came with the wrong size hardware for my fathers bike which is industry standard ISCG05 mounting bracket."
"The chain guide itself is not bad, not as sturdy as a name brand like E13 or MRP, but it is simple and it works."
"Chain guard is as expected but the screws that come with it are two small for the bike frame."

Reviews
"While the tool can be used to put the pin back in (if the pin isn't completely out), I found it easier to just use a hammer. I would not use this tool to put back a standard link while on a bike because of the bending."
"Either way it took about 30 seconds to figure out how to get the chain off, and about 120 seconds to figure out how to get it back together so win win and its well build."
"Well, it was easy enough to remove chain links with this thing, but there were no instructions included with it at all, so I couldn't figure out how to use it to reinstall the pins into the links."
"I put my Kindle Fire on bluetooth speaker and listened to Josh Turner as I replaced the front deraileur."
"This tool worked very well and pushing the pin back in to secure the links."
"From the integrated piece of curved wire to hold your chain while you insert the pin, to the adjustable link holder (probably not the technical name), this made short work out of what is usually a chore."
"Not only did it cut the chain easily and cleanly, but with a little care, and a needle nose pliers to hold the pin, I was able the mend the chain as well when it turned out the missing links, despite being the apparent correct size, did not work."
"I was worried about the durability of this tool, but I haven't been disappointed yet."

Reviews
"I gotten a brand new mountain bike and was plagued with chain coming off in every manner possible."
"I do suggest a size down with less teeth if you're biking in an area with steep hills, this is more for a moderate or flowing hills type biking, but I can't think of needing one bigger than this, but get a size based on your biking style or your area (Moab definitely smaller!)."
"Put a 43t on my specialize sworks with 12 / 27 cassette super smooth didn't have to do anything but put on race face and ditch the front derailer works great with original dura ace short cage rear derailer. Not having the front derailer on a road bike is super nice especially at race pace."
"The trails I rode on are pretty mellow, but there have some slow and fast rocky downhills, a few drop offs and small jumps."
"I recently purchased a Diamondback Line MTB, and it came with a junk chain guide and tensioner."
"Overhauling an old mountain bike for street use."
"I now have 38T front chainring after converting by 2006 Specialized Epic Comp to 11 spd rear cog (40 x 11) (26 inch wheels)."
