Description
Special model with durable surface treatment Kashima Coating
GROWTAC is a Japanese manufacturer that develops and sells bicycle-related products. GROWTAC develops a wide range of products for bicycles.
EQUAL mechanical disc brakes, which have been attracting a lot of attention recently, have the world's highest level of braking power and lightness, not to mention the peace of mind that only mechanical brakes can provide in terms of maintenance.
They are ideal for severe braking in road racing and cyclo-cross, They can also cope with problems during wheel rides and long rides, It is a next-generation braking system that is easy to use in a variety of situations.
Kashima Coat is a high-performance surface treatment based on hard anodizing, to which molybdenum disulfide, a solid lubricant, is
added to reduce friction and improve wear resistance.
In the field of bicycles, it is known as a treatment with a proven track record in harsh operating environments such as MTB suspensions, which are constantly subjected to repeated sliding and contact.
EQUAL brake calipers use Kashima Coating on the caliper body and piston.
It is scratch-resistant and stain-resistant to maintain a beautiful appearance for a long time.
It also suppresses performance changes during long-term use, maintains a stable braking feeling, and improves
brake feeling.
World's lightest weight class Caliper
To achieve both high rigidity and light weight, high-strength super duralumin was used and almost all parts of the caliper were machined at high precision. The caliper is one of the lightest mechanical disc brake calipers in the world at 136g (including brake pads, flat mounted). The entire braking system, including cables and other components, is comparable to a high-grade hydraulic braking system. Recommended for serious racers and hill climbers who are concerned about weight.
Brake System Total Design
Total design of the brake system including cables and pads. Special hard outer casing with less deformation for high transmission efficiency. Inner cables are NISSEN slick stainless steel cables for lightness of pull. Brake pads are jointly developed with Vesrah, using resin-based ceramic semi-metal (EVO RESIN) friction material and aluminum back plates for high braking power and durability. All the necessary performance for brakes in high quality. All in a set, of course.
Brakes FEELING Adjustment system
The world's first brake feel adjustment system. The brake feel can be adjusted to suit your weight and preferences. You can choose to focus on control or increase the initial braking force. In addition, the pad clearance can be adjusted independently on both sides without steps, allowing for fine-tuning for your particular needs.
Optimal brake lines
EQUAL also focuses on the brake line. Optimal brake lines reduce sliding resistance, resulting in lighter braking and improved transmission efficiency. They are also easier to install and look better.
