Kool Stop Replacement Bicycle Disc Brake Pads (XT/Grimeca/SRAM, Organic)

My daily return commute takes me down some of Seattle's steepest hills. After some experimenting and much puckering, I have eternally settled on these for my lifesaving brakes.I have tried running regular resin brakes and have found them about 65% effective. Once the kool-stops have quickly bedded-in, they are 100% effective.By the time I get down to Lake Union, my discs are actually sizzling HOT. The Kool-stops can take a daily parachute run and will laugh it off for 6 months. As they eventually wane, they gracefully start to fade rather than dangerously disintegrating, giving you ample warning that they needs a-changing.In fact they grip so hard that I don't trust my A.D.D. self riding with Kool-stops on my front brakes, and run the Shimano resins in front to stop me locking up my front wheel after I come out of my 40mph dream haze and process the senior citizen/rat/squirrel/haughty hipster etc. crossing my path.If you are closer to neuro normal and can pay attention to surroundings, I would wholeheartedly recommend these brakes on the front or back wheel of any bike.When I placed an order for the rectanguloid Shimano pads with the single tab, I was never graced with an actual picture of the actual final product (that I wanted AND got) from the seller. Pay attention to the part number you need and if the part number looks good on your final order, you WILL get the correct brake pads. C'mon Mr./Mrs. brake seller!- it's a leap for customers to commit when the model number is good and the picture shows some "who-knows-what" brake pad!!"Buy me and stop one" vs. "Drink the Kool-aid."

I’ve used Kool Stops on rim brakes for years. They’re great.I wasn’t sure if their disc pads would be as good. Happy to say they are - superb stopping power.

Long story short: if you hate your Formula brakes, give these pads a try before you throw them out.Read on:My 2014 Specialized Epic Comp came with Formula C1 brakes, which is universally hated if you Google it. The C1s gave a mushy feeling at the levers and were underpowered, and they squeal like madness and were embarrassing to use on the trail. As a courtesy, my LBS bled the brakes and lubricated the pistons. This helped a bit but they were still under powered with no modulation to speak of. Using these brakes were only slightly better than jamming a golf club in between your spokes to stop.I tolerated these brakes for about 700km until the stock pads were worn, and I was ready to toss them out and buy a pair of XTs. By some miracle my buddy gave me a pair of these Kool Stop pads to try and MY GOD did they transformed the crappy C1s!! My brakes are now QUIET and actually have power! I immediately went on Amazon to buy another pair for my rear brake.The backing plates are red, and I think they made my C1s look more expensive, which is an added bonus!

I,like others who reviewed this product, was under the impression that these pads would fit all Promax brakes. They do not fit the 310's that came with my Cannondale. I know that one pad is thicker than the other. That is not the problem. The diameter of the entire pad is too large. They will not fit into the calipers. I have always liked Kool Stop products, and I am sure that they would be great if they fit. This is why I gave 3 stars even though I will be sending them back. I guess I will have to try a brand that I have not used before. I have not had the best of luck with bicycle parts lately. It is really frustrating!!

I have only had one ride with these so far and it was a race. They did an okay job of stopping, just as good as the original pads did. I would rate these brake pads as equal to the original pads that came with my formula brakes. They squeaked a little at first while I was trying to brake them in. I would recommend these to another. The only reason I didn't give this a perfect score is that I think they could have just a bit stronger grab.

My Formula R1 brakes were making a horrible warbling noise with the original pads. Some would describe the noise as a gobble or chuckle. The original pads were organic and both front and back were making the noise. I switched to these Sintered pads and the awful noise when away. Now these just make a light squealing. Much better. I may try the semi metallic in the future to see if I can avoid the squealing and warbling.

Installed in the rear set of my GT I-Drive Four 2.0 and they're stopping really well, after about a half-hour riding of break-in. I can't tell if they're much-improved over stock, as I'm not quite sure if I had stock pads in the brakes before this or not, the bike was purchased used but these are working well and I'll probably buy another pair for the front.

Side by side comparison with stock Formula Oro pads I cannot tell a difference. I have stocked up and bought 3 sets of these pads. I will buy more of these just a great deal. They stop very well and do not squeal. Wear is comparable to the other brands.Update: 10-20-2012 These pads have great wear. This is my 2nd set I have replaced and consistant as the prior. All fit is exact with no rubbing or brake squeal. I'm about to sell my bike and will use these on my new bike. Again...great deal.

J'ai mis du temps a trouver de bonne plaquettes mais cette fois-ci impeccable, plus de bruit au freinage et très bon grip même en descente pour une utilisation XC-Trail / All- mountain
