The brand-new lotus tooth process provides extra light weight with improved chain stabilizing capability, compared to traditional narrow-wide tooth process.
Forging from an entire piece of 7075 aluminum, the lotus process minimizes the thickness of the pulley for lighter weight, while leaving the wider tooth thicker for enhanced performance.
The lotus tooth process, named after its complex angle design, 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, with inclined angle instead of right-angle, lotus tooth process also helps pushing these friction and damaging factors out, maintaining the chain at optimal performance state.
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.
Why replace derailleur pulley
First, 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.
Second, 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.
Third, 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.
