1. MATERIAL
Standard: Full Toray T700 Carbon fiber
Premium: Combines Toray T700 and T800 Carbon fiber
The leading suppliers, representing 70% of the total market, of the type of carbon fiber used for the manufacture of bicycle parts are Toho Tenax, Toray Industrial and Mitsubishi Rayon, all based in Japan. All our carbon fibers are imported from Toray Industrial.
For bikes and bike parts, T700 carbon fiber can be used singly as a material to make into products. T800 are not suitable to be used to make products separately because while it is very light, it is also very stiff and brittle. The T800 should be used with T700 carbon fiber together to improve the stiffness of products.
It's not feasible to build 100% T800, as T800 is very stiff, but also too brittle for 100% composition. It is also costly! We believe the combination of 25% T800 and 75% T700 is optimal to achieve a stiff and strong rim, at a lightweight, that still has some compliance to avoid cracking and chipping and give the rider some compliance for bigger bumps.
If some sellers tell you that their bike and bike parts are made fully from T800 carbon fiber, which is not feasible due to the qualities of the material. T1000 is mainly used for in the aerospace industry, and because the cost of T1000 is very high it is not generally found in the mountain bike industry. If a seller is telling you their material is T1000, please be attentive to the reality that they may not be telling you the truth.
This is the main driver for the price difference between the two series of rims, so that you may benefit from some weight savings and increase in stiffness.
Only a fool will look for logic in the chambers of the human heart...
