Product Detail

FEATURE

-Wider rim system offers improved aerodynamics,

better handling in crosswinds condition and faster riding.

-Tubeless ready design, it makes road clincher rims better tubeless setup and better sealing,

also to ensure an easy mounting and a safe tire seat on the rim.

-Hookless Rim Bead. Hookless rim bead more straight and smooth side walls, tire can touch rim walls fully.

More durable and impact resistance compared to the traditional hooks rim.

-U aerodynamic shape makes road tubeless rims lightweight

but still stiff, keeping them stable in cross winds condition.

-High TG resin temperature 255° brake track, solve the heating problem on the rim brake clincher bicycle wheels.

SPECIFICATION

Best selling Road Bikes

How to choose the high quality rims?

The criteria that matter most important for the best all-around wheels for road disc bikes are as follows:

Performance: Versatility, aerodynamics, crosswind management, stiffness, acceleration, comfort, and handling.
Design: Wheel weight and material, rim depth, rim inner and outer widths, rim profile, hub and spoke design, and wheel finish.
Quality:Durability, warranties, and service/support.
Cost: Purchase price, cost of ownership and replacement cost

WITH BALANCED SPOKE TENSION TO BETTER RIDE

carbon fiber wide rims

Experience A better ride with perfectly balanced spoke tensions.

Width 65mm fits more forms of cycling and keeps riding in great stability;

Deep section (34mm) could make fat bikes be used for more aggressive cycling forms;

A wider tire and a wider rim together provide better handling.

The wider rim sets the foundation for the wider tire to better keep its shape as you can see in the drawing on the left above.
The square shape of a wider rim supporting a wider tire provides a wider “contact patch” than on a narrower tire.

While the total area of the tire patch for both tires is the same as long as your weight and the tire pressure are the same,

that area spreads further across the width and less along the length of a wider tire.

A 23C tire on a 15C wheel– this is the likely stock or upgrade alloy bike wheels

and tire combination you have as a baseline on bikes made before 2016.

You know how it rides. This is still a perfectly good width combination in my view. What follows are your options.

A 25C tire on a 15C wheel– somewhat improved comfort over a 23C tire but worsened speed and handling for reasons described above.

Better to reduce pressure 5psi or so on 23C tire for better comfort without losing handling performance.

Neither combination is going to be an aero star.

A 25C tire on a 17C wheel– better comfort but no better speed or handling than a 23C tire on a 15C wheel.

23C tire on 17C wheel at right pressure will get you somewhat improved comfort with improved aero

if the rim has at least a rounded nose rather than box or V profile, is >35-40mm, and you are riding at 18mph/29kph or faster.

A 25C tire on 19C or 21C wheel– better comfort, improved speed and handling over options above.

A nice set-up for long endurance rides at a good average speed (18mph/29kph or higher) especially on deeper (>35-40mm) and preferably rounded profile wheels.

But, most alloy bike wheels aren’t going to be that deep or have a rounded rim profiles where the spokes join the rim.
