Key Features

Mid-hook design

Tubeless ready design

Super light 4:6 lay-up design to minimize the rotational weight

Extra inner width for 28-35C tires

Internal&external nipple systems available

Contour rim bed shape design for better tubular tire sitting

Asymmetric design for a stiffer, stronger and more reliable wheel

Mid Hook Design

For the disc brake specific rim family, we ultimately worked out a Mid-Hook design. 

With this technology, the rims could be as impact resistant as MTB rims, and 80g lighter than rim brake models. 
These new mid hook rims could take much higher tire pressure, as high as 90PSI with a 28C tire. 


Super Light 4:6 T800 40%&60% T700 new structure 80g lighter than the regular disc brake rim

Thanks to our engineers’ hard work, the disc brake rims eventually realized a super light structure with 40% T800 without any sacrifice of strength.  
We made fatigue and impact testings, and the results were very good. 

It's always so important to have a lighter carbon rim because a smaller inertial weight could make riding more efficient.


Wider TirDesign

Road disc brake frames are now designed with wider tire clearance to accept larger tires. Larger tires mean higher air volume and lower tire pressure. 
It's proved that larger tires can provide improved rolling resistance, comfort, stability, and better performance in cornering. 
So the internal width of the new disc brake rims starts from 21mm. This width is optimized for 28mm wide tires. The riding experience would be totally new.


TubelesCompatible

The tubeless system is lighter and provides better traction, no pinch flats, lower rolling resistance, more comfort, etc. 
We designed all our rims to be compatible with tubeless tires for the lowest possible rotational inertia weight.



Ultra Smooth Inner Wall

A specially shaped bladder is used in molding the rims. 

Comparing with traditional bladder, it's designed in the correct size and shape to correctly support the rims inside. 
The result is that we could see a very clean and smooth inner wall, which means the carbon fabrics are stretched smoothly and optimized. 

This could ensure the best strength of the fabrics.


Asymmetric Design

The featured Asymmetric design could help to optimize the spoke tension for the drive side and nondrive side. 

This would create a stronger and stiffer wheelset, and with fewer fatigue issues.

Asymmetrical rims build up into stiffer, stronger, and more reliable wheels by improving the bracing angles of a dished wheel and equalizing the spoke tensions between the drive and non-drive side spokes.  
For disc brakes, both the front and rear wheels have significant dish. With traditional rims, the rim is centered (or dished) by decreasing spoke tension on one side relative to the other so that the rim is pulled into the center.
