ZTTO Gravel Bike/ Road bike Hydraulic Flat mount Disc Brake

Mechanical Wire And Hydraulic Brake

brake wire pulls the main piston, and the main piston hydraulically drives the two sub-pistons. so you can use the old shifter to upgrade disc brake for your bike.

About Adapter

Only One adapter and it's for the front. which is normal.
why?
please look at the install holes of fork and frame, they are different. The rear brake is directly installed without adapter (for 140 rotor). If your fork and frame have the same mounting hole, then you are probably looking at the wrong product. I guess your standard is 74mm PM. Please go to check MTB brake for that.

About Disc Brake- New Rotor and Pads

brake-in period is very common and popular in vehicles and motorcycles, but it may be the first time for people riding road bike to hear about it. The braking force of the new disc brake is relatively small at the beginning, which is a normal, especially the new disc, it will greatly affects the braking force. You need to use it for a period of time, and the braking force will gradually increase. If you want to know why, please search the information about the brake-in of the vehicle brake. There are many detailed explanations and the principle is the same.

CNC made, weight :

310g (Front and rear brake)
116g(140 Steel Disc)
85g (140 floating disc)
115g (160 cooling disc)

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 high strength steel disc as standard setting .

Front brake 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. If you feel that the braking force is not enough, you can easily change the front brake to 160 disc.

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, you can choose floating disc even cooling disc.

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.

Easy to find replacement parts

Using common pads ,same as E5/E7/DB1/DB5/Level T/
