 1.Different from other brands with eccentric designs, we designed these two products adopting the SRAM concentric design. The benefit of such design is that it won’t have any negative impact on neither the crisp shifting feel nor the tooth capability of the cassette nor 

This is also the exact reason why Shimano ceased the production of 6800/9000 and upgraded their design to R8000/9100.

Therefore, we choose 12T/17T over 17T/17T.

Compared to original transmission system with 11T pulley, our products decrease friction resistance by 45%, ceramic bearing pulleys save more than 2.2 watts on average with each pedaling, increase shifting speed by 20-26%. Enhanced chain stability by implementing narrow-wide tooth upper pulley for more accurate and crisper shifting.

 

2.Extended tooth for lower pulley, to prevent chains from coming off.

One thing to clarify is that, it’s not wise to implement narrow-wide tooth to any situation.

Yes, narrow-wide tooth provides better stability, but it is achieved at the cost of more friction resistance. As designers and manufacturers, we aim to be adaptable, to provide different products for different occasions, to suit your need best, not bragging a certain “high tech” which looks fancy but brings negative impact for your experience.

 

3.Titanium alloy CNC shaft.

To pursue the goal of lightweight, we overcame as many obstacles as possible, even it’s just for 2-4 grams of improvement. Shafts of products for ETAP and mechanical are both made of 6/4 titanium alloy. Even in original SRAM products, titanium shafts are only available with RED RD, not even ETAP, ETAP shafts are made of steel.

 

4.Patent design for ultra-lightweight concentric upper pulley structure.

One 7075CNC screw to fasten 7 pieces. Easy to maintain or customize while remain light and durable. 

 

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.
