Five Advantages

①
Floating disc technology:

maintain the flatness of the disc under high temperature, so that the disc is always

   stable during long-distance braking

②
Lightweight technology:

using aerospace-grade 7075 aluminum alloy disc core, large hollow disc surface,

   the weight is reduced by 5 compared with ordinary discs.

③

Super-hard stainless steel disc surface:

effectively improve braking force. The average braking force is

   increased by 9 compared with G3 Disc.

④
Wear-resistant disc:

Using stainless steel wear-resistant performance to increase the service life by 30
compared with ordinary carbon steel disc.

⑤
Hollowed disc:

Provides excellent heat dissipation performance, while hollowing out, adding levers to make

   more strengthen so that ensure the rigidity of the disc

Product Design Features

1

.High-Strength Stainless steel dish body.

Different thickness settings are used for large-diameter and small-diameter

discs. Small-diameter 140/160mm with lightweight and easy assembly features for low-load Road bikes brake system.

Large-diameter 180/203mm brake disc rotor are designed for high-load MTB & E-Bike system which enhanced weight

load and rigidity.

2.All disc rotor use full round shape,

UCI approve ready, more safety at any times.

3.Brake rotor has unique bar construction design

between each two fix pins for high stability when at high brake

temperature.

4.Unique hollow out design

make half brake surface in a raw to keep brake pad warm up at right work temperature quickly.

5.All rotor size have same large floating pin design

for more force trans and more cooling surface.

6.All spindle made of AL7075,

for large size 180mm/203mm, use different stronger size hold on more brake force.

About our Brake Disc Roter

A floating disc is made up of two parts. An aluminum center carrier, which is mounted on to the hub of the wheel and a stainless steel rotor on which the brake pads apply pressure.

The stainless steel rotor is affixed to the aluminum carrier with help of rivets. The setup allows the rotor to move axially to align with the brake pads, thereby allowing for optimum contact between both the surfaces. This optimum contact enable better braking and also increase the brake pad life by evenly distributing the heat generated.

The other advantage that such a setup offers is in terms of better manageability of thermal expansion. When a solid disc heats beyond a limit, it will start to warp, whereas floated disc has enough space and margin to allow for thermal expansion.All high performance braking systems now use a floating rotor designto these very advantages offered by them.
