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.
Hoekom vervang derailleur katrol
In die eerste plek die plek van die oorspronklike katrolle met hierdie sal die swak stuk van die oorspronklike stel verbeter, en maak die op en af ketting spanning tussen gids wiel en ratte baie meer voldoende.
Tweedens, die aantal kontak tand of beheer tand tussen ketting en ratte van 17T is meer tydens rat verskuiwing, hoe meer kontak, hoe sterker is die beheer krag.
Derde, nadat herontwerp die hok se rotasie kurwe, is die afstand tussen die boonste gids wiel en die ratte verbeter.
Lang storie kort, met al die eienskappe wat hierbo genoem is, sal jy 2,2 watt of meer met elke trap red. Dit is die ekwivalent van skeer 100g af 'n 10kg fiets.
