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.
Bakit palitan derailleur pulley
Una, palitan ang orihinal na pulleys na may mga magpapabuti ang mahina kahabaan ng orihinal na set, at gawin ang mga up at down kadena tensyon sa pagitan gabay wheel at cogs mas sapat na.
Pangalawa, ang bilang ng mga contact na ngipin o kontrol ngipin sa pagitan ng chain at cogs ng 17T ay mas sa panahon gear paglilipat, mas contact, ang mas malakas ang control kapangyarihan.
Ikatlo, pagkatapos ng muling idisenyo-ikot curve sa hawla, ang distansya sa pagitan ng itaas na gabay wheel at ang cogs ay mapapahusay.
Long kuwento maikli, na may lahat ng mga tampok ng nabanggit sa itaas, nais mong i-save 2.2 Watts o higit pa sa bawat pedaling. Iyan ang katumbas ng pag-ahit 100g off ang isang 10KG bike.
