Carbon Disc Wheels 700C Clincher 28mm Wide With R12 Ceramic Hub

Aero-technical design with U-shaped cross-section. carbon 700C clincher rims 28mm wide outside and 21mm wide inside, with 22/33/38/44/50/55mm depth options, tubeless ready.

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.

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.

Ceramic bearing is harder than steel bearings (up to 30%), which improves durability, and they also don’t rust for less maintenance.

carbon wheelset 700C disc brake with ORNAN R12 ceramic bearings hubs and Pillar 1423 spokes, more economical carbon wheelset. perfect for your daily training, riding use.

 ORNAN R12 CERAMIC HUB TECHNOLOGY

The original design was completed by the ORNAN engineer team. This is a road bike disc brake hub, suitable for carbon gravel, carbon 700C road bike disc brake wheels, etc... We call this hub the R12 model.

The picture on the left is our 3D design model, equipped with ceramic bearings, please see the details of more pictures below...

R12 road disc brake hubs are designed with 6-pawl freehub system. 72 POE_Point of Engagement. 36teeth, to make the force more direct and minimize power loss, improved durability and quicker response. 

At the same time, we are equipped with ceramic bearings to reduce rolling resistance. Because ceramic bearings are rounder, smoother and more uniform in size than traditional ones. 

Ceramic bearing is also harder than steel bearings (up to 30%), which improves durability, and they also don’t rust for less maintenance.

TECHNOLOGY

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.
