THE 1st ADVANTAGE:The special lotus tooth pulley design provides extra light weight and improved chain stabilizing capability, compared to traditional narrow-wide tooth design.

THE 2nd ADVANTAGE:The titanium alloy shaft is fixed to the aluminum alloy base. It can evenly distributing the force to the entire carbon fiber plate. will save 60% frictional resistance compared to original 11T pulley.

THE 3rd ADVANTAGE:If you buy the ceramic bearing version, it can save save 2.4 watts on average each pedaling, shifting speed increased by 20%-26%.

THE 4th ADVANTAGE:The lotus tooth design, named from its complex ANGLE DESIGN, it decrease the contact area between the tooth and the chain, less contact, less friction. Furthermore, the said contact point is where grease, dust and mud accumulate point, But inclined angle instead of traditional 90degree angle, lotus tooth design also helps pushing these friction and damaging factors out, maintaining the chain at optimal performance state.

THE 5th ADVANTAGE:For Shimano MTB series, the upper pulley implements an optimized 14t lotus design, with more complex curve angle and tooth shape, preventing abnormal chain movement while shifting which is commonly found in cassette extension modifications, i.e. 46T to 50T, resulting lower noise and friction, and faster smoother shifting experience.Carbon fiber bracket

Carbon fiber is a new type of fiber material with high strength and high modulus fiber with a carbon content of more than 95% Carbon fiber is "flexible on the outside and rigid on the inside". Its mass is lighter than that of metal aluminum, but its strength is higher than that of steel. It also has the characteristics of corrosion resistance and good stability.

CNC Machining Process

Full 7075 aluminum alloy CNC cutting lightweight guide wheel ,Heat treated CNC process Guaranteed strength Lightweight at the same time,The surface anodizing treatment enhances the hardness and wear resistance of the aluminum alloy surface, and prolongs the service life of the product.Lighter weight

Carbon fiber cage, aluminum alloy guide wheel, Carbon fiber cage combined with aluminum alloy guide wheel makes the entire product only about 54 grams,perfect lightweight design.Ceramic Bearing

If you buy the ceramic bearing version, it can save save 2.4 watts on average each pedaling, shifting speed increased by 20%-26%.

NOTICE:Bearings have 3 specifications (Ceramic bearing version Ceramic Bead Bearing Version NSK Steel Bearing Version), this description focuses on ceramic bearings, you can choose according to your needs

The product is taken in kind and displayed from multiple angles, showing you more different product scenariosWhy Replace Derailleur Pulley Wheel

Firstly,replace the original pulleys with these would improve the weak stretch of the original set, and make the up and down chain tension between guide wheel and cogs much more adequate.

Secondly,the number of contact tooth or control tooth between chain and cogs of 17T is more during gear shifting, the more contact, the stronger the control power.

Lastly,after redesign the cage's rotation curve, the distance between upper guide wheel and the cogs is improved.Long story short, with all the features mentioned above, you would save 2.2 watts or more with each pedaling. That's the equivalent of shaving 100g off a 10KG bike.
