Size:11T Structure: Ceramic bearing Material: aluminum alloy 7075 Color: Black Red Blue Silver Gold Weight: about 7.8g Fit for 4/5/6 MM roller screw axis Apply for most of rear derailleur on the market ZTTO CERAMIC PULLEY Suitable for all cycling applications, whether it is road, MTB, or triathlon, these pulley wheels will optimize your speed rear derailleur with reduced friction and extended lifetime. Being the fastest spinning bearings on your bike, an upgrade with our high-performance pulley wheels are an effective way to save energy or ride faster. Aluminum Pulley Wheels Weighing only astonishing 7.8g grams, these lightweight pulley wheels are fitted with hybrid ceramic bearings, which reduce friction and feature increased lifetime. The aluminum alloy is very durable, and together with the pulley design, the set optimizes the overall performance of your derailleur. The removable design also makes the maintenance much easier. POM Bearing Rings For guide pulley, we use POM bearing rings instead of steel bearing rings, POM is an engineering thermoplastic used in precision parts requiring high stiffness, low friction, and excellent dimensional stability. They are also extremely light weight, that is why we can make a 7.8 grams pulley wheel. They are also resistant to water and salty environment and they will never need lubrication or getting rusty. ZTTO Premium Hybrid Ceramic Bearings About ZTTO Premium Hybrid Ceramic Bearings ZTTO bearings feature rolling balls made of a ceramic material. The rolling balls are constructed of silicon nitride or zirconia ceramics. Using ceramic bearings in hubs, bottom brackets, and pulleys will reduce friction. By reducing the coefficient of friction, you can accelerate faster and maintain speed with less power input. Benefits of ceramic bearings: Ceramic bearings have 10% less friction than steel bearings. Bearings are extremely wear resistant because ceramic material is much harder than the hardest steel bearings. Silicon nitride balls are 60% lighter than steel balls. Safe operation even when using low amounts lubricant, which reduces the viscous drag friction from lubricant. When used with special seals and lubrication, the friction in ceramic bearings can be 20-30 times lower than steel bearings with standard friction seals and standard lubrication. There are different types of ceramic bearings on the market, such as full ceramic bearings, steel ceramic bearings and nylon ceramic bearings. Full ceramic bearings make use of both ceramic balls and race. These bearings are impervious to corrosion and rarely require lubrication if at all. Due to the stiffness and hardness of the balls and race these bearings are noisy at high speeds. The stiffness of the ceramic makes these bearings brittle and liable to crack under load or impact. Because both ball and race are of similar hardness wear can lead to chipping at high speeds of both the balls and the race this can cause sparking. So, instead of the full ceramic bearings, the best solution for bicycle is hybrid bearings. ZTTO use hybrid ceramic bearings for high-end applications. Compared to all steel bearings, they have lower friction, lighter weight and longer service life. They are also less susceptible to failures caused by dirt, dust and poor lubrication. Ceramic bearings have 10% less friction than steel bearings. Bearings are extremely wear resistant because ceramic material is much harder than the hardest steel bearings. Silicon nitride balls are 60% lighter than steel balls. Safe operation even when using low amounts lubricant, which reduces the viscous drag friction from lubricant. After-sales service: We will check the goods quality before shipment. If there are some unexpected problems happen, we hope to solve the problems with buyer smoothly in the following ways: 1. If it is quality problem, buyer can submit argue within 15days after receiving the goods, but buyer must provide photos or video and other evidence to seller for identify. 2. Man-made damaged, buyers take full responsibility. 3 .Product quality processing choice: 1) The buyer return the goods to us and responsible for return shipping costs. We will send a new product to buyer and pay for the resend shipping cost, after we receive the goods . 2) If the goods (total price including shipping freight is less than 5USD) has quality problems, we will resend a new product in next order; if buyer don not plan to make a new order in the near term, buyer can pay the resend shipping cost and ask us to resend a new product. Tax: Paying tax is the duty of every citizen, clearance is the responsibility of the buyer, buyer need to responsible for the all of taxes. If buyer refuse to receive the goods for tax problem, buyer need to responsible for freight out and home. Feedback: 1 .We depend on our customer satisfaction to succeed.
