2022/05 New Upgrade:

1. Adjusted the angle of the brake lever, it is now more comfortable to hold.
2. The special model oil needle on the brake side is gone, replaced by the common BH59. So don't worry about the trouble of replacing the hose.and the oil cooler is still there 🙂

Since the above upgrades did not significantly change the appearance, so we did not change the picture yet, thank you for your understanding

Cooling Brake Pad Available

We have cooling brake pad version can be choose, cooling brake pad was helpful for a long time brake use, cooling down faster than normal version, save brake life time and better performance

Original Full Metal Pads-same as XT pads- MJ-01F/ G01S/ J03A

There are many benefits of full metal pads, greater braking force, stronger heat resistance, stable braking force regardless of sunny or rainy days,But because it is harder, it takes a period of running-in before it can work normally. At the beginning, the braking force is small which is normal, it will get bigger and bigger. And a slight braking sound is normal for metal pads.

4 Metal Pistons

Upgrade 4x14mm pistons caliper structure, it's make the brake pads more balanced and create more brake force. The piston is made of aluminum alloy, it's strong and has excellent heat resistance.

Cooling Connecter

Heat control is very important for stable performance, after using all-aluminum brake and heat sink pads , we even made a cooling fins for the tubing! This is a great invention. these fin will cooling the oil directly!

Cable Angle adjustable

Caliper hose connecter was rotatable, there is no repression like fixed cable.

Pad Contact Point Adjustment

An advanced feature, you may have to spend hundreds of dollars to get it in other brands. but we made it in this price 🙂

Required small fingers strength, but big brake force, feel relaxed in the long downhill, Brake performance is not affected by weather changes, still stable, not easy to be affected by soil or rain.

ZTTO Cylinder Ratio and Brake Linearity

The brake equired strength is small, in the long downhill, fingers and arms are not easy to feel tired.Brake performance is not affected by weather changes, still stable, not easy to be affected by soil or rain.
