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.
Wêrom ferfange derailleur pulley
Earst, ferfange de orizjinele pulleys mei dizze soe it ferbetterjen fan de swakke trajekt fan de oarspronklike set, en meitsje de op en del chain spanning tusken gids tsjil en Cogs folle mear foldwaande.
Twad, it oantal kontakt tand of control tosk tusken keten en Cogs fan 17T is mear ûnder gear ferskowe, wat mear kontakt, it sterker de kontrôle macht.
Tred, neidat werynrjochting fan de koai fan rotaasje kromme, de ôfstân tusken de boppeste gids tsjil en de Cogs wurdt ferbettere.
Lang ferhaal koart, mei alle eigenskippen neamd hjirboppe, jo soenen bewarje 2.2 watts of mear mei elk pedaling. Dat is it bedrach fan likernôch scheren 100g ôf in 10KG fyts.
