Product description

THE 1st ADVANTAGE:Compared with other brand 17T+17T pulley design, KACTUS TECH adopt the coaxial swing cage system to design the upper 12T/lower 17T system, lighter weight and more stable.

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 45% frictional resistance compared to original 11T pulley.

THE 3rd ADVANTAGE:If you buy the ceramic bearing version, it can save save 2.2 watts on average each pedaling, shifting speed increased by 20%-26%

THE 4th ADVANTAGE:The narrow-wide teeth design of the upper 12T pulley on the derailleur strengthens the left and right binding force of the chain, for more accurate and crisper shifting.

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 60 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

1.Full 7075 aluminum alloy material//2.G3 Silicon Nitride Ceramic Beads//3.Ceramic Zirconia

Multi-color options

A variety of colors are available, you can choose the color you like according to your needs, there is always one that suits you.

Why Replace Derailleur Pulley Wheel

Firstly,porous spring position limit could adjust back tension largely, improve the weakness of original weak stretch, and make the up and down chain tension between guide wheel and cogs much more adequately.

Secondly,the contact tooth number or control tooth number between chain and cogs of rear derailleur 17T is more during gear shifting, it just like to pinch the middle and two sides of some sticks, the larger the control lever, the stronger the control power.

Lastly,after redesign the cage’s rotation curve, the distance between upper guide wheel and the cogs is improved.
