    Bike Setup:K2 Razorback Team SRAM XO Easton XC 50/70 XT crank DT wheel set
    Bottom 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

    Bike Setup:1992 Trek 950 singlespeed conversion
    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.

    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: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?

    Strengths:Seems to work
    Well made
    Fairly inexpensive
    Weaknesses:Difficult to install
    Chainstay clamp too narrow
    Supplied bolts too short
    Needs constant maintenance (tightenting)
    Similar Products Used:None
    Bike Setup:2002 Norco Launch
    Bottom Line:Bought this device so I could have access to middle and small rings, while tensioning the chain on big-ring DH runs. Extremely difficult to install - forget about using the stock bolts, go get a handful of longer ones before you even start. The chainstay clamp has to be mounted behind the arc of the crank arm, or you run the risk of the arm hitting the clamp. The clamp itself is too narrow - even with the bolts tightened to within a hair of thread failure, the clamp rotates on the chainstay.

    This device works on the bikestand with the bolts tightened, but if the chainstay clamp/pulley arm fixing bolt loosens, or the clamp rotates on the chainstay, shifting the chain to the big ring will push the pulley arm out into the crank arms' path, crushing the arm between the crank and frame. Ouch.

    Bottom line - this unit is okay for DH racing, where you check your bike after every run, but not for everyday use. Too bad - with a little more engineering, it could be a winner.

    Bottom Line:I use this product for single speed conversion. It mounted in 5 minutes, and stayed tight with piece of rubber wrapped around the chainstay. I slightly modified it by flipping the guide upside down so that the chain was pulled away from the chainstay, then I increased the tension to the max setting. I positioned it so that it was slightly closer to the rear cog. The chain nice and tight and hasnt derailed yet. It was hard to find to find chain tensioners at the bike stores, I guess they are not really in demand. I didnt want to use the derilure (not sure how to spell) because it doesnt look clean. Good for single speed conversions.

    Bottom Line:When I first installed this I was going to kill someone or the chain reactor. It wouldn't fit around my rear fork, but I really wanted it on there. So I drilled a small hole through the frame and mounted it directly to the frame. It didn't work at first; kept making the rear and front derailleurs jump gears. I cursed, threw tools, and the reactor.
    The next day I signed on here and noticed people said to get it very tight. I went back to the bike tightened the screw through the frame into the reactor as tight as it would go. Works great now! A little noisy, but worth it.

    Bottom Line:If you can't install it just be honest and go to the shop like I did. I paid an additional 10 in labor to have him wrap the lower arm in an old bike grip and use longer screws (applying his knowledge to the problem) and it worked GREAT. Just ripped it off the frame on a huge rock this weekend but up till then it's worked wonderfully (tore the chain in half and almost broke the frame if that helps). I am buying a replacement kore reactor as I use three gears + outside bash guard and love to jump off stuff. This chain tensioner when installed correctly works just great. Honestly what are all the other great choices? Looked to me like the MRP Recon was $120 and I lost my big gear. Seems like some of you didn't get it installed right. That's a bummer as it does work just killer like you thought when you purchased it......the application just wasn't correct.

    Strengths:Laser-etched logo, WAY cooler than derailleur-type tensioners,
    simplicity of unit
    Weaknesses:Noisy, despite Kore's claims of quietness due to neoprene wheel. Neoprene maybe, quiet...NOT...will hafta try the inner tube trick from below. Tough to get in the right spot. Not much clearance from 1.9 Specialized Team tire.

    Bike Setup:1990 Trek 930...single speed. Fully rigid, OLD school DiaCompe canitlevers (from about 1985-MAFAC style), LX hubs/el-cheapo, double-wall Weinmann rims, some rubber thrown on for traction, LX cranks. I have two setups...36/17, and 32/15.
    Bottom Line:I bought this for a single speed conversion on a frame with vertical dropouts. I had used all of my spare derailleurs and was not satisfied with them, maybe because of the 'geared' look it added to the simplistic SS. It took quite a time to find the best spot for mounting, then it hits the chain a little off-kilter. It is rather loud, when compared to a derailleur. I find this product to work very well on this pretense...since it 'tightens' toward the chainstay, you MUST already have your drivetrain adjusted almost perfect...for a SS anyway. It will NOT adjust for a longer chain like a derailleur-type chain tensioner, at least for a SS. I think that it works fine for me, and no one who rides a SS around here has one, so there is always a fanfare of 'does it work?', 'cool tensioner', 'why only one speed'. If you can buy it for less than the $39 MSRP, buy it, you'll like it.

    Bike Setup:Random GT hardtail, XTR shifter/brake levers (gotta love good brakes), XTR/XT drive, storm control rear tire for all the damn rain we get here, blah blah
    Bottom Line:This product works.
    If you have half a brain, you will realize that MOST of the bad reviews this product has received are either from people who did not read or comprehend the installation instructions (check out the kore website--there are even pictures, dood) or complete idiots. (remember i said most) Some modification will probably be necessary--i just had to get longer bolts.
    I am a pretty avid XC rider, and i take the bike out about 3 times a week and thrash on it. I regularly take 3+ foot drops with this product, and it has never failed to retain my chain through all the trauma that would previously drop my chain to the inside about 5 times every ride (yeah, my front derailleur was adjusted correctly)and it really quieted my chain down.
    For the weight and price, this product rocks! If you have a really fat chainstay though, or are a 7-foot-drop downhiller, you might want to stay away. Too bad the clamp isn't universal, but maybe that'll be next year's model... Just uh... like remember to put thread locker on all the bolts--like the instructions say--duh.
    Since this product has taken so much bashing, and i love it so far---i give it a perfect 5. So there.

I guess MRP is making one now, but it is over $120, and that's more than this college student has. But never in my life have I fought a component like this one. It never was aligned right. The bolts never stayed tight, and then the thing broke. Looking back, it was a blessing that it broke because I could quit messing with it.
    My new bike is an Azonic DS-1, and the chainstays are way too big for it, so unlike KORE says, it won't fit every size chainstay.
    Overall, I wish I hadn't ever seen one.

    Bike Setup:Planet X Zebdi stock trials.
    Bottom Line:Good product. If you can get it for $20 or less it's worth it. One downfall is that there's that much more to bash when you screw up a sidehop. Forgetting this was installed, I landed directly on mine on the first ride. Bent the b'jeezus out of it. However, I got home, took it apart, bent the cage arms straight in the vice, put it back together, and it's running just fine. Plus now it looks nice and broken-in.

    Duration Product Used:Less than 1 month
    Price Paid: $35.00
    Purchased At:Cambriabike.com
    Strengths:I don't know yet.
    Weaknesses:Everything you read from this review really tells you the majority of the installation. It doesn't matter if you have the round, square or triangular bar, installing it just does not work. Bolts are short and hex hole is weak. To the KORE company I hope you read all these reviews to make the product a whole lot better
    Bike Setup:Univega DS900 XTR compnents, W420 FIR Rims, Easton VRS DH
    magnesium, Thompson seatpost, Easton monkey lite CT2, Kenda
    Kharisma Crystal, Chris King headset, Marzocchi Z1 Bomber.
    Bottom Line:I was expecting a little bit more from KORE. I guess no one really is perfect. I would suggest to check all the reviews of any parts anyone would like to buy first before actually getting it.
