1. Patent Tiramic Bearings - Tiramic Bearings: A patented product of Token Products Inc. that is composed of a set of Titanium
coated bearing race & cone, combined with solid ceramic balls & Kluber lubricant.
- Patent No.: M304599 2. TBT Distinctive Mark - All Token Products equipped with Tiramic Bearings carry a distinctive "TBT" Sticker or
Laser Etched Logo
- Token Products equipped with Tiramic Bearings include: Hubs, Integrated BB, ISIS Drive BB, Square BB,
Rear Derailleur Pulley, Headset 3. Tiramic Bearing Technology (TBT) - Non-Corrosive
- Weight Reduction: Ceramic Balls are 60% Lighter than Steel Balls
- Durability: Lifetime 5~10X Longer than Steel Balls
- Accelerate Faster: Speed Increase Approaching 4%
- Smooth Rolling: Ceramic Balls are Rounder and Smoother than Steel Balls
- Low Friction: To keep momentum
- Less Vibration: Resulting in a smooth ride
- Resistant to Contamination 4. Token Tiramic Bearing Grease: TK400 TK400 is a combination of ester oil, synthetic hydrocarbon oil, mineral oil and Barium complex soap.
This combination makes it an excellent lubricant for rolling bearings and can be easily applied
by brush, spatula, grease gun or cartridge. It has a service temperature range of -40°C-130°C
with a Kl ber viscosity grade of M.
All these characteristics make TK400 the perfect complement to Token's Tiramic Bearings.
- Increased Corrosion Protection
- Superior Resistance to Environmental Elements
- Increased Resistance to Mechanical and Chemical Induced Corrosion
- Excellent Load-Carrying Capacity
- Improved Sealing Effect 5. Reinforced, stabilized nylon cage The ball cage is made of heat stabilized nylon with 33% fill short fiberglass reinforcement
for added strength.The nylon material provides a natural lubricity for longer life.
Fiberglass reinforcement allows higher operating temperatures than plain nylon,
yet is more resistant to fatigue than metallic cages. Short fiberglass allows greater
flexibility than steel or normal fiberglass, especially under misalignment.
That means longer life in mounted bearings where some degree of misalignment
is unavoidably encountered. 6. Dual lip labyrinthian low-friction seal This special designed seals keep the grease inside the bearing and prevent dust and/or water
from getting in.
The light-contact type seal has a high-quality water proof function with extremely low friction.
Resulting in smooth clean rolling, longer lasting lower maintenance bearings. 7. Ceramic Balls - Ceramic Ball Characteristics

- Fatigue resistant 9. Tiramic Bearing comments from Athletes "I began using Token's Tiramic Bearing Pulleys in the spring of 09' Since then I have had no
issue with them.The Tiramic Bearings do make a noticeable difference in reducing chain
drag when compared to other pulleys I have used. They spin incredibly freely, shed dirt
and grime better than others. Thanks to their design they always catch stares from
other riders. A truly outstanding product and well worth the nominal investment."

Tiramic Bearings. Starting Torque:
- Normal Bearing is 0.27
- Tiramic Bearing is 0.20
- The rate = 0.20/0.27*100% = 74%
This means that the Starting Torque of Tiramic Bearing is only 74% of Normal Bearing.
That's why you can get "Lighter Pedaling".
Turing Torque:
- The Normal Bearing is 0.15
- Tiramic Bearing is 0.10
- The rate = 0.10/0.15*100% = 67%
This means that the Turing Torque of Tiramic Bearing is only 67% of Normal Bearing.
That's why you can get "More Smooth Running".

这好像是自己换Ceramic Bearing 的.gif)
，我开这个贴是要求证，市场上很多脚车店都说Ceramic BB 很滑很耐用，对！ Ceramic Bearing 确实真的比钢珠Bearing强，但是不是市场上的Ceramic Bottom Bracket （BB) 的Bearing 珠子真的是Ceramic 的材料。.gif)
