Lets talk Tech
SPEEDPRO wheels are all hand selected to suit all riding styles. We only use the best brands the market has to offer. World renowned DT Swiss is one of our suppliers as we offer the DT 180, DT 240 and DT 350 Hubs. They are then complemented with either Sapim CX-Ray Spokes or Pillar PSR Spokes.
Rim Braking Tech.
The carbon fiber clincher may very well be the perfect wheel: it’s fast, light, and strong, with the added benefit of convenient-to-change tires. They are some of the hottest products in cycling today. There has been a flood of new carbon clinchers into the market, with vastly differing levels of quality. Our carbon clinchers utilize our own patented heat resistant resin in the production that allows them to safely withstand the extreme heat(240 degree) and force created under different cycling condition, even the hard and long braking without any heat failure.
We have the test machine in the factory to test the rims/wheels, the machine works by spinning a wheel using a chain and simulated rider load and then applying braking force while measuring temperature at multiple points hundreds of times a second using laser technology. The machine can also precisely measure wheel and tire width and see how these dimensions change as braking is applied and heat is generated.
Carbon Fiber Materials.
- Patent high temp resin: unlike other smaller factories who purchase the finished carbon fibre, we import Toray T700 filament directly from Japan and do pre-preg with high temp resin by the weaving machines, it makes our carbon rims safely withstand the high temperature 220 degree Celsius under long descending from the hill down.
- Filament winding machine made: we use the machine to shape the rim bed, so each carbon fiber layer can be evenly distributed and tightly bonded, enabling its strength to reach a maximum value.
Our engneers are trained carbon experts, they constantly study the latest poducts from all of the leading carbon filament producers and use that knowledge to develop new materials.
The lighter a rim or frame is, the stronger the material has to be. All of our carbon products use a combination of T700, 800 and 1000 filaments from Toray in Japan, the world’s largest producer of carbon fibre – most of it is used by the aeronautical and defence industries. We also use filament from Mitsubishi Rayon, with the combination of Toray and Mitsubishi carbon fibre helping us to deliver the superior ride quality of every carbon products
