Perfect combination of power, modulation and reliability

The Delta 2 is a powerful hydraulic brake that offers excellent modularity thanks to its 4-piston calliper. It has been designed for mountain bikers who wish to do a series of descents with complete confidence, and fully satisfies the needs of e-bikes requiring additional power due to an increased weight load. Dependability is a core value at Bontaz, and as such the Delta 2 brake has undergone a vigorous battery of tests to ensure sustained, reliable performance. Like all Bontaz brakes, the calliper and master cylinder are fully removable for total repairability.

Powerful and progressive braking

The optimisation of the lever travel and the 4-piston calliper action result in an excellent braking modularity. The power and overall performance of the Delta 2 brake equips the rider to confront any given situation.


Lightweight and resistant levers

The Alpha 2 levers were developed and designed in-house from Carbontaz +, a material derived from high-tech composites with glass fibres added for more resistance. They are also removable and interchangeable.

Easy guard adjustment

Thanks to the dial located at the same level as the master cylinder, the guard can be adjusted manually to adapt the grip. This offers the huge advantage of being able to make adjustments at any time.
