weight : 270g (front and rear brake)/ 169g(disc)
CNC made

Upgrade! New version

In response to the shortcomings of the first version, we have made improvements. Now the piston is more sensitive, the oil circuit design is more balanced, and we have also reduced the price by reduce unnecessary design.

The new version uses metal pads and normal disc as standard setting . if you still want floating rotor please jump to new version link to check.

140 and 160 compatible

In the new version, we have redesigned the appearance so that it can be compatible with 140 and 160 at the same time by the same adapter

what's the different between old and new ?

The new version is an improved version of the old, which mainly optimizes the piston and oil circuit design. Changed to metal pads, no heat sink, because it is not needed, the metal pads have strong resistance to heat, and the disc is changed to a more cost-effective style , Of course if you need luxury configuration, please check another link of ztto official store. the new version use DB1 brake pads, the old one use m8000 pads.

Flat mount for Road bike

Do not buy it wrong, it's different from MTB brake ! please check the size first.

Sometimes we receive some questions like this : Is it hydraulic or mechanical?

Both. The brake is filled with mineral oil. brake wire pulls the main piston, and the main piston hydraulically drives the two sub-pistons.

Don't worry about the piston

Yes, we have noticed that some buyer say that only one side of the piston will move. I think we need to explain something. (unexpectedly that so many road bikers use hydraulic disc brakes for the first time), this is very common for hydraulic disc brakes, No matter it is an MTB or a road bike brake, no matter how advanced or expensive your brakes are, all hydraulic brake systems and even vehicle brake systems will have such things happen, but at the same time it is very easy to solve.
In general, you just need to hold the moving side, which will make the lazy side move, and then give the piston a little lubrication. Repeat a few times. It only takes one minute to solve this problem.
A famous blue tool brand has a video to teach you how to solve it, but we can't write a link here due to copyright reasons. You can search by yourself or contact us to get the video link. So don't worry, these brake working good .

Flat mount compatible

Fit for most of road/ gravel bike ,
Front 70mm mount / Rear 34mm mount

Original Cooling pads

It's ready for a long downhill. After upgrading to disc brakes, no matter how you use the brakes, you don’t need to worry about rim damage.

Light weight brake system

270g (front and rear brake)/ 169g(Rotor)
the whole brake system only about 20g heavier than the common C caliper, but in exchange for stronger braking force and no need to worry about the brakes overheating

Original Floating Rotor

Good brakes also need good rotors, this rotors combination of hardened aluminum alloy and high-strength steel. Not only looks good, but also achieves excellent performance such as light weight, high strength, and good heat dissipation.

Easy to find replacement parts

Using common pads ,same as M8000

Black / Red Available

My Dog Approves of this Toy for Agressive Chewers
My dog is a mix of a Husky and a Pit Bull. She needs to chew toys, but they usually don't last long. This one seems to be an exception. She took to it right away, and it's still in one piece pi. I assume that the bacon flavor or scent is what keeps her coming back to this toy. This one seems to be her favorite so far.

Fantastic toy for aggressive chewiers!
I have bought two of these for my granddaughters three dogs and they love them! In fact, I only bought one to see if they would, and all 3 played with it! One is a 5 year old pit mix, one is a 9 mo. lab mix, and ine is a 10 year old shepherd mix! Miss Lab goes through toys like melting ice, so they reall have to be well made. Not even Kong toys have made it with her! All three dogs have made it squeak, which we didn't know it did! If you have an aggressive chewier, this is the toy you need to put in the #1 spot on your list to buy!

Great chew toy
My dogs love this toy and we still have it a month later. That’s impressive since they are aggressive chewers.
