Bike Disc Brake Kit, Including Front and Rear Caliper, 160mm Rotor, Mechanic Tool-Free Pad Adjuster for Mountain Bike, Road Bike, Fixed Gear Bike, MTB, BMX

A very easy installation and a very effective and awesome caliper & rotor combo especially having BOTH front and rear along with bolts that fit all my threads perfect like factory! And it looks super cool, The red calipers contrast my blue and black bike. I bought another e bike and got another pair of these incredible brakes to put on it! The first pair I bought for my first E bike still stop on a dime! I finally got my back rim off of my ebike ( a LOT of work but worth it) and put the rotor on that came with the brake set. WOW! I was wheelieing riding fast in some trails & the back brake (with the correct rotor) SAVED me from looping out at 20 MPH. GREAT brakes, the lava red is SO COOL!

These are a great replacement to your existing pad style brakes. And the fact that you get both the rotors and the calipers for the price of most rotors alone is a no brainer. Surprisingly well made and the two most popular mounts are in included. The prefect replacement for cheap 'over the wheel' style and lots of adjustment options are available to get them tuned to your biking style.

Everything is great

I can't say they're easy to install because I had never installed brakes before and it took my brain a few minutes to figure out the orientation and such. That was my brain's fault, not the product's. Now I know how to install disc brakes for the first time on a bicycle. At least on mine.I'm so glad I did.I already had a disc brake on the front tire but the back one had the rim-type brake. I didn't realize how much better it would break with two disc brakes. It's amazing. They are a little squeaky towards the end of the braking curve, but it's worth it for the increased length of my life that will be gained.I would definitely recommend these brakes and they're well worth the price.

Definitely worth the moneyWorks very well

At first I didn't seem to get a lot of grip out of these, but after I roughed the pads (and they stopped minor squeel) they really dug in and stop on a dime now. My objective was to improve braking over the center-pull rim brakes and they definitely do that. I will be converting my wife's bike with these next.

UPDATE WITH REPLACEMENT BRAKE PADS 03/25XTR indicates the pad material and does not help finding the correct size pads. After much searching and measuring, these pads are Shimano BPO2 size, that number does not help since they all go by what caliper they fit. the best number I found to search is BR-M9020 (9000/987/988/985) The metal backing plate for the friction material is 32MM wide, 16MM height, and the overall height to the top of the pin hole is 30MM. Hope this helps avoid the frustration I had.I will say despite being disappointed at the condition, they work well so far. We'll see the end of the season how well they really hold up.At least the pictures on the product page don't lie, when it shows loose parts in a box that's exactly what you get, no packaging and no instructions. Sure I can figure it out, but a basic place to begin would save some time.Calipers are all beat to crap with chips and scratches in the paint, dings in the aluminum castings, and red paint transfer on the rotors, which thankfully don't seem to be bent. A empty bag which I can only guess held the small baggie with mounting screws in it for the rotors, laying at the bottom of the box along with some little pieces of tissue paper.I don't know if this is how they're supposed to come, but it pretty much looks like I got somebody else's return just thrown in a box, or a complete afterthought made up up of mis-matched parts.I manipulated both calipers by hand and they appear to work smoothly so I guess there's no internal damage otherwise I'd send them back.IMO... If your looking for a set of mechanical disc brakes, I'd suggest you look elsewhere.

Great brakes for my mountain bike disc brakes, love the color as they remind me of Brembo.
