My KORE CHAIN REACTOR (correct name) is far better than the last two devices I used. It looks like the Kore boys really gave this one some serious thought. Its very quiet and smooth. All my gears shift with percision.I also have the Kore Elite stem that is of excellant quality as well.

This is a great little product. It was easy to install and setup (took less than 10 minutes). My only complaint came when I first spun the chain over the little wheel on the Reactor. It made a fair bit of noise -- sort of made my bike sound like my tire was rubbing the chain stay. Then an idea came into my head; I cut two small loops (about 1/2) of rubber out of a road bike tube and stretched them over the wheel; perfect fit & the wheel is now completely silent. In addition, I no longer have to worry about the wheel wearing from use -- as soon as the outer layer of rubber is worn out I simply have to cut a new band. One inner tube should last anyone their entire riding life, so no problem at all.Anyhow, since installing I have no more chain slap, and I have even improved my front shifting. Wow!

Basically, if you dont want your chain to flop around, get rid of your derailer, or get a chain guide and dont worry about it. But I do admit this is a good product for bmx

Last year at the New England Mountain Bike festival, I bought a Kore Chain Reactor cause of the good price. After try for an hour to get it to work correctly ( it would suck the chain into the wheel, wouldn't shift in to the larger cogs and was louder then my chain hitting the chain stays), I brought to back to the guys at KORE to have them put it on. The funny thing was they couldn't even get it to work. You know it's a great product when the people that make it can't even get it to work!

I use the CHAIN REACTOR down hill uphill through mud and water without any problems NOW! I had the same problem as some of the other reveiws with the arms of the Reactor rotating outward. Well I felt pretty dumb to find out that the bolt at the bottom pivot should be locked down tight after adjustment. This really is a work of art when properly used. Great product

The Chain Reactor was a worthwhile investment... I've tried all the others, including the TWP Sidewinder, which from a design perspective should kick the most ass. The Kore is definitely better. Only problems I had were getting a good positioning on my chainstay, because of tapered tubing. A piece of inner tube wrapped on top of the Lizardskin (yes, on top) took care of the slop. I swear my shifting has been crisper in addition to the chain staying very quietly on my drivetrain. If you've got chain problems, get the Kore.

THIS CHI-CHI KICKS ASS!!!!!!!!!!!!!! Forget the Ringle chain suck, You need to put two screws in it to keep it from rotating, but the KORE CHAIN REACTOR is so smooth I dont even know its on my bike!! You must remember that when its all adjusted to the right position you need to lock down the pivot screw on the bottom to keep the arms from swinging out. I noticed alot of people figure thats supposed to rotateat the bottom -NOT SO, I called Kore on it. ITs the GREATEST!! 10 CHILES

I installed the Kore Chain Reactor (installation is very, very simple) on my Schwinn XT Homegrown because of a bad chain slap problem on rough terrain and it has really worked wonders. As to the one reviewer who complained about a)wouldn't work with a Lizard Skin
chainstay protector and b)the nut on the pulley came loose. Well, there is a very simple solution to each problem. a) Cut the Lizard Skin in half and install each half fore and aft of the mounting bracket on the Chain Reactor or, better yet, get one of those nice thick rubber WTB chainstay protectors and do the same. b)Put Loc-Tite on the pulley nut. In fact, you should Loc-Tite all the nuts on your bike.
