- - It can be used on the tube in the frame to effectively prevent the chain and chain from jump.
- - It must be small and light, and it must be strong and durable, so we use solid 7075 CNC aluminum alloy+ABS plastic as a raw material with high hardness and long service life.

Before installing this, I was dropping my chain multiple times consistently on a 20 mile route. Since installing this, I've done 70 miles and my chain stays right where it belongs! I installed this on a Turbo Creo eBike. The horizontal and vertical adjustments were sufficient to place the chain guide exactly where it needs to be positioned.I read through some of the negative reviews. It seems to me that some consumers were simply careless with the installation. 1. If the clamp is not sufficiently closed around the seat-stay, then the Allen bolt is not going to be inserted directly into the threads. If you force the bolt under this condition you will strip the threads! Back the bolt out, tighten the clamp and reinsert the bolt. It should thread smoothly. Do not force it! 2. The lower part of this assembly is plastic. That's fine. This means that if this becomes misaligned you may lose a $20 chain watcher, not your $60 chain. You can make it back without the former. But you need the latter! Anyway, it's plastic. Keep that in mind when you are tightening this down and you'll be fine.It's great! It's doing exactly what I need it to do. I couldn't be happier!

After I upgraded a low gear-ratio 7 spd freewheel, Revo shifter, and 38T crank to a Shimano 7 spd freewheel with 34T high gear, Shimano lever shifter, and Powerglide 48T crank. On a 10-mile test ride, the chain jumped the chainring the times. I had to baby the pedals to get home. Installed the guide and took the exact same 10-mile trail riding aggressively with NO chainring jumps! Highly recommended...

i installed a toseven dm01 motor on my mtb with a 1x12 speed rear cassette. my mtb has boost spacing soi had to offset the motor which negatively affected the chainline. my chain was coming off the front chainring when on the biggest rear cog. so far, this device has eliminated that problem and it feels very sturdy once installed.

Oct 2023 one year update:My 8-year-old son rides his bike offroad over bumps and grass. His chain was coming off or getting stuck several times a day; these issues were leading to his falling. Since I installed this chain guide, in the past year, the bike chain has not come off or gotten stuck. He also has not fallen due to any chain issues. It is now rare for him to fall. It's been a true lifesaver. The build quality is decent. Avoid over-tightening the screws or you may strip them.
