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.
Mengapa menggantikan derailleur katrol
Pertama, mengganti puli asli dengan ini akan meningkatkan peregangan lemah set asli, dan membuat atas dan bawah ketegangan rantai antara panduan roda dan roda jauh lebih memadai.
Kedua, jumlah gigi kontak atau kontrol gigi antara rantai dan roda dari 17T lebih selama pergeseran gigi, semakin banyak kontak, semakin kuat daya kontrol.
Ketiga, setelah mendesain ulang kurva rotasi kandang ini, jarak antara roda panduan atas dan roda ditingkatkan.
Singkat cerita, dengan semua fitur yang disebutkan di atas, Anda akan menghemat 2,2 watt atau lebih dengan masing-masing mengayuh. Itu setara dengan mencukur 100g off sepeda 10kg.
