New Rim Technical
Using advanced aerospace composites technology; our designs equalize the stresses throughout the carbon fibers. Careful application of layup of carbon sheets allows the best balance between the strength and weight. With years aerospace experience and professional finite element structural analysis, we optimize the layup for strength, weight, and to consider braking loads so our wheels still elevate the performance of talent athletes and elevate the safety of their equipment.All this care we put into design, layup, and manufacture results in improved strength to weigh and quality levels than most other rims on the market.
Smooth molding technology means the Carbon fibers in our molding process do not get wrinkled. This means no damage to the carbon fiber structure and the fibers remain straight and better able to carry loads. The surface will not produce pores and means we don’t need to need paint rims.All this care we put into design, layup, and manufacture results in improved strength to weigh and quality levels than most other rims on the market.
Our preference is to make rims of unidirectional carbon fiber without any coating. This reduces excess filler material as the fibers are all laid flat and not woven which causes small pockets of low strength resin everywhere. The use of unidirectional sheets of carbon fibers increases strength to weight ratios considerably. It also results in the least porosity of the molded material ensuring a perfect surface finish again without any painting or coating required for appearance reasons. Meanwhile, no coating means no surface grinding. The grinding applied to other brands of rims will result in damage to the surface fibers.
The newest technology we are applying to our rims is smooth molded holes with no drilling. The molded holes result in a rim with no increase in weight over traditional drilled spoke holes, but increased strength by around 60%. In each spoke hole is embedded a thin metal cap which is molded into the structure during manufacturing. The cap helps distribute the load from the spoke nipple over a larger area decreasing the effect of the stress concentration. Additionally as the hole in the carbon fiber structure is molded in, the fibers are continuous and not cut during drilling. With no interrupted fibers in the structure and better load distribution our rims maximize strength and stiffness without adding weight.
On our deeper more aero focused rims we can offer internal nipples as an option. We can offer this on most rims we provide but they are more popular on the deeper rims as internal nipples are more aero. For some seeking the best aero performance this is more important than ease of spoke retensioning (if it is ever needed).
We make intelligent choices as to the carbon fiber material we use. Combine the high performance “prepreg” we use from the US and our design and manufacturing methods; it all results in the high quality that we stand by. For rims that have to tolerate high temperature from braking we use some specific material with high thermo stability developed for booster rockets. The high grade resin increases the total heat tolerance to about 230c. This reduces the risk of sidewall failure due to heat buildup under heavy braking which has been a major concern with clincher rims in particular.add picture of booster rocket firing flames for extra effect ;)
