ZTTO Gravel Bike/ Road bike Hydraulic Flat mount Disc Brake

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

So cute and so worth it!
Size: 3 Little Kid, Color: Turquoise
AMAZING for my 7 year old daughter. She can tie shoes but I no longer have to wait on her to do so. It takes 2 seconds for her to put these on and she says that they are super comfortable. We have been to Silver dollar City multiple times and she never complains about her feet hurting! They are easily washed in the washer. They hold up great. I think they are very much worth the money! Fit normal.
