Product description
THE 1st ADVANTAGE:
The 17T pulleys can save up to 60 frictional resistance compared to original 11T pulley.
THE 2nd ADVANTAGE:
If you buy the ceramic bearing version, it can save more than 2.4 watts on average each pedaling, shifting speed increased by 20-26 for Shimano Systems.
THE 3rd ADVANTAGE:
This 17TR biycle rear derailleurs can compatible up to 11-28T, 11-30T or even 11-34T cassettes. only need to add a tail hookhanger. So they can be called the fastest RD pulley set in the world.
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.

17TS & 17TR installation tips:
1.
due to increased offset by the oversized pulley system, please make sure your RD and frame are aligned and calibrated correctly.
2.
please check the length of your chain. Here is how to calculate, chain should be 10-20mm longer than the RD at 0 tension shown as the picture below when rests on the smallest chainring and smallest cog.
3.
to lower the requirements for chain length and RD/frame alignment, we introduce the new 16T pulley system, 17TS and 17TR. Compare with 17T, the power saving would be lowered by about 0.2 watts but increasing chain stability and shifting speed.
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 cages rotation curve, the distance between upper guide wheel and the cogs is improved.
Product installation process
1. Rear derailleur decomposition, remove the original pulley wheel cage, as shown in the figure original pulley wheel cage has been removed, removal method please refer to figure No.20
2. Please confirm the aluminum alloy ring different side surface.
3.The main bolt gasket.
4. Install the nylon washer to the rear derailleur.
5. Mounting the main bolt gasket in the bolt, and apply grease.
6. Take the 17T carbon fiber pulley wheel cage, use No. 2 hex wrench remove alloy screw out on the back of the pulley wheel cage.
7.Remove upper pulley wheel.
8. After removing the upper pulley wheel, install the center bolts on the back.
9. Before installation the main bolt, the bolt should be fully greased.
10. Push the main bolt fully in the base of the pulley wheel cage.
11. Please confirm the alloy ring groove surface into the main bolt, and groove surface has greased.
12. Please confirm the alloy ring plane outward, and the alloy ring has greased.
13. Please confirm the spring mounting hole in rear derailleur.
14. The spring pin alignment spring mounting hole into the rear derailleur.
15. Confirm the spring pin into the base of the spring positioning hole.
16. Install the spring.
17. Aligned the spring pin with the hole on the pulley wheel cage.
18. Marked in 1 to 4 is tension adjustment hole, the default initial mounting is hole 2. tension: 4>3>2>1
19. The pulley wheel cage fully pressed into the rear derailleur. confirm the main bolt alignment.
20. No. 4 hex wrench to tighten the main bolt to 4N.m.
21. Reset the upper guide wheel, insert the upper pulley bolts, but not tightened.
22. Rotating the pulley wheel cage to rear derailleur rebound limit block, press the topupper pulley wheel bolt out, blocking the limit block.
23. Tighten the upper pulley wheel bolt.
24. The installation is complete.

Product description
THE 1st ADVANTAGE:
This product is made of AL7075-T6 round bar CNC. It is finished with diamond knife, has diamond-like metal texture, and the appearance of the product is resistant to friction index. All good. Adopting the Japanese imported steel ball lining, the rotation has no resistance, which greatly reduces the frictional resistance and improves the riding efficiency.
THE 2nd ADVANTAGE: Optimized narrow-wide tooth design, increasing shifting speed, decreasing friction resistance, enhancing chain stability, suppressing shifting noise.
