700C Carbon Disc Wheelset with DT Swiss 180 HubsORNANBIKE 700C carbon disc wheelset with DT Swiss 180 hubs

The Orn728 carbon rim features a U-shaped cross-section with a 21mm internal width and 28mm external width.  The 28mm outer width keeps the aerodynamics optimized with smoother rolling for your 25c and 35c tires. Orn728 series disc brake 700C carbon clincher rims are 50 to 60 grams lighter than rim brake versions.
Constructed with T700 and T800 carbon fiber, the rim uses a double-wall structure and is designed for compatible 700×25C–35C road tires.
The tubeless-ready rim bed supports both compatible tubeless systems and clincher tire setups with inner tubes.



DT Swiss 180 Ratchet EXP 36 Hub System

The wheelset features DT Swiss 180 straight-pull disc brake hubs with Ratchet EXP 36 technology and SINC ceramic bearings. Meanwhile it paired with Sapim CX-Ray aero spokes for a performance-oriented road wheel build giving the hub extra lightness, stiffness, precision and easy no-tool maintenance. Ideal bike wheels for the professional or racing cyclist.


Whatever you want the shallow rim to save the rim weight or higher profile for time trials. There will be one to meet your need.

It can be used as both race carbon rims or daily driver's rims.

TECHNOLOGY

Orn728 carbon rim with 21mm internal and 28mm external width


1. Tubeless Compatible Technology

The bump on the rim bed helps to create a buffer during tire inflation, making the mounting process easier. The bead locks allow for an easy switch between clinchers and tubeless setup.


2. Ultra Smooth Inner Wall

Use specific, thinner, high-pressure air bladders to control the inner wall smoothness, 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.


3. Fast Tire Installation

Easy installation and removal of normal tube tires and tubeless tires.


4. Double Wall Design and Aero Technology

We use a double wall design to better control the rim strength and stiffness during layup. Rim profiles are specially designed with aero gains and drag reduction in mind.


5. Customized Spoke Hole Angle Drilling Technology

High-speed CNC machine tools drill carbon fiber rim spoke holes. Customized according to the geometric angle of the hub. Check all drill holes to make sure they are free of burrs.
