Strengths: None, The product alone is garbageWeaknesses: The product alone is not versitile enough to fit anyone bike. It probably only fits one lolBottom Line: When I read the first 10 reviews I thought to myself...Do any of these ppl do any of thier own maintenance on thier bikes other than change a tire? Granted it does take a little work, but if you want this to work and work well, replace the bolts, nuts and bearings before you even install it. Honestly there are just some frames that it just wont work on, but after making the proper modifications ($15 worth). It works like something that you'd probably pay 3-4x as much for! Read the reviews and learn from other's mistakes $30 is nothing for how effective it will be afterwards. I ride here in miami,fl and its not but roots and rocks and cause parts to go back prematurely from chain suck

Strengths: Cheap, light, simpleWeaknesses: Challenging to install properly.Bottom Line: I bought the Chain Reactor to run my old Trek as a singlespeed commuter. On this old steel frame with small, slightly oval chainstays, the KORE fits pretty easily. I had read the mtbr reviews that said it doesn't fit some frames, so out of curiosity I tried it on my XC FS bike which has a carbon AMP rear end. There is no way it would ever fit the large rectangular carbon chainstay. Never. On the Trek, I just put it where the chainline dictated and put a piece of inner tube under it to keep it from slipping. I don't ride the Trek in sand or mud so I expect it will be virtually maintenance-free.

Strengths: does what it needs to do. Keep the chain from bouncing off track. Pretty easy to get on. the roller is nice and smooth and doesnt put wear on the chainWeaknesses: it barly is able to fit on the chainstay. Its not exactly the right shape for it. it swivels way to much from where the arm meets the clamp.Bottom Line: So far i have had no problems with this peice. Iv been doing FR on my XC bike and needed somthing to keep my chain in place cause it bounced off track on hits. ONe of the best things on my bike. Pays for its self too. dont have to buy new deraulers

Strengths: Looks neato. In the box. On my porch after UPS dropped it off. Why was he laughing? Oh, now I know.Weaknesses: Could not install on my Enduro. Chainstays are too big.Bottom Line: Why, oh why didn't I consult the reviews here? It's only when I received the unit and realized there were no instructions that I Googled. That only brought me back here, and after seeing the reviews, that saved me from expecting too much. I Googled again and found the instructions on Kore's site. I tried to install the unit, but quit after a few minutes, realizing it was going to be futile.
What size hex do they use? It's not on my bike tool or in my regular toolbox. They wouldn't have used American sizing, would they? That would be pretty stupid.
But not as stupid as me for buying this thing without consulting MTBR. I'm sending it back. I hope.

Strengths: easy set-up. anyone who had trouble with this is a retard.Weaknesses: i got ripped off.Bottom Line: only bought it to do a retro race at big bear (downhill race on a hardtail). i used to lose the chain all the time, now i don't even worry about it. if you're gonna be doing a lot of downhilling, buy an mrp. if u want to spend $20 on something to help the chain stay a little better, buy this product

Strengths: none (piece of junk, made by Da Bomb)Weaknesses: NOT KORE, weak spring, crappy set-up (it's made by Da Bomb)Bottom Line: a real piece of %$#&. save the twenty, use an old derailluer, or buy a real KORE product.

Strengths: LooksWeaknesses: Peace of Junk, hardware is cheap, won't ever install right on most frames, goes off track and ruins your spokes.Bottom Line: Most expensive keychain I've ever purchased. If you race dh or ds buy something more expensive. If you ride xc save your money, adjust your derailer, converting to a single speed, buy a Surly Singleator.

Strengths: Lite, cheap, worksWeaknesses: Stock bushing sucks chainwheel stops spinning after 2 ridesBottom Line: Stock this thing sucked. But I liked the idea so I stuffed 4 mini cartridge bearings in the chainwheel after I drilled it out. Made a bracket to fit the large chainstay of the slx & now it works great. No Chain slap, suck, or droppin any mo fo me. It's even lighter now w/out the heavy brass bushing! So if like to take on a little mechanical challenge this product can be one of the best additions to your rig. If you don't like to modify parts to make them work stay away. Cheers

Strengths: It would have worked great if bolts provided were a little longer.Weaknesses: It keeps popping off track that damaged my spokesBottom Line: This is only compatible to some bikes unless you find a bolt that you want to pay extra for but then a gain for the price that i paid for it should come with free dinner!

Strengths: Damn cheap...seriously wondered if it would work at that price. Seems to be holding up so far and haven't lost my chain yet...I think I got my $13.00 worth!!!Weaknesses: Had to replace pretty much all the hardware that it came with. I replaced the stock nuts with self-locking nylon nuts and had to get longer bolts for my chain-stay...why didn't it come with longer bolts? Who has a bike with that narrow of a chain stay that the stock bolts would fit on? Took a while to get it setup right and a lot of patience...Bottom Line: Well worth the $13.00, despite all my whining about having to go to Home Depot for the bolts and such. I go to Home Depot weekly anyhow, this was just another excuse. I've spent more on crappy lunches than I spent on this...it's not bad and I would have to recommend it to anyone with more patience than I to put it on!
