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.
Poukisa ranplase derayeur pouli
Premyèman, ranplase pouli yo orijinal ak sa yo ta amelyore detire nan fèb nan seri orijinal la, epi fè moute a ak desann tansyon chèn ant gid wou ak cogs pi plis apwopriye.
Dezyèmman, ki kantite dan kontak oswa kontwòl dan ant chèn ak cogs nan 17T se pi plis pandan Kovèti pou déplacement, kontakte a plis, pi fò nan pouvwa a kontwòl.
Twazyèmman, apre repanse koub wotasyon kalòj la a, se distans ki genyen ant anwo wou gid ak cogs yo amelyore.
Long istwa kout, ak tout karakteristik yo mansyone pi wo a, ou ta sove 2.2 Watts oswa plis youn ak pedale. Sa a ekivalan a nan bab 100 G. sou yon bisiklèt 10kg.
