HP series carbon rims are jointly designed by professional cyclists and carbon fiber specialists. The demands of serious cyclists and their requirements for high performance carbon rims are key in our design. This product will be a speed weapon that will excel in any situation.
HP series carbon rims not only perform best going uphill, it are also excellent in terms of rotational inertia and low wind resistance. It is definitely the fastest carbon rim! There is no other choice!When you first ride with HP series carbon rims, it will be an incredible riding experience. The ease of acceleration and excellent climbing performance will inspire great confidence. When you are climbing the high rigidity and lightweight features will improve acceleration and efficiency. It will enable you to easily drop your competition!
You can descend with confidence, thanks to superior, stable braking performance.
Do you want to know how we did it?
1. Excellent acceleration performance!
Currently, as the depth of carbon fiber rims increase, the strength of the rim sidewalls will weaken. The rim sides can even deform when pressed by hands.
The power transmission becomes weak due to deformation when pedaling. Just like the loss of power caused by soft, flexible frames and forks.
Our HP series carbon rims utilize Evonik's high temperature resistant and high strength structural ROHACELL PMI foam and uses special carbon fiber laminated structure. Both the carbon rims and sidewalls have become a stable unit(see attached). When a rider stands on the pedal, the hard rim sidewallswill effectively apply 100% of the force to the tires, which combined with the lightweight advantage of HP series carbon rims,results in excellent acceleration.
That is why we researched and developed HP series carbon fiber rims—To make the fastest carbon fiber rims!
2. More suitable for installation without wire beads!
Most wire beadedtires are used for training wheelsets. For high-end competition wheels, it is best to not use wire beaded tires to achieve the lightweight feature.
Although this two types of tires are both 700c/28" size, it is more difficult to mount the tires without wire due to its characteristics. We have considered this situation when we were designing HP series rims.
The adaptive design of tires bed makes it easier to assemble without steel beads.The combination of both tire and tire bed will be reliable and it will not cause the tires of falling out.
3. Contactless spokes cap base!
The spokes cap in the inner rims will take up to 140kgf of spokes tension. This is related to the rim strength directly.
The spokes capbase in normal carbon fiber rims are reinforced by carbon fibers with no more than two meters. Each carbon fiber will overlap over 25mm to maintain its strength. For HP series rims, we not only need to meet the requirements of each carbon fiber’s strength, but also achieve the light weight feature. The spokes cap base of HP series rims is reinforced by up to 25m of t1000 carbon fiber, it is combined with multi-angle carbon fiber,thusthere will not be any seams. This also avoids weak bonding strength and eliminates the need to add more carbon fiber to strengthen it. Compared to normal carbon fiber rims, HP series rims weigh 20% less without sacrificing strength.(See attached)
4. Carbon fiber vacuum assisted laminating technology!
We produce our HP series carbon rims using strict aerospace manufacturing processes and technologies.If there are excessive voids in the inner carbon fiber products, the fatigue resistance will be reduced.
This is also a very important requirement in the aerospace industry. In order to make a perfectbond between the carbon fiber layers, we perform 3 separate vacuumcure steps in the production of each rim. This makes a multi-layer fiber rim that is compact and free of voids.
