This is the only full carbon fiber oversized pulley system for SRAM 1X on the market, made of reinforced TORAY carbon fiber from Japan, thickened with OFFSET design, which keeps the position of the pulleys in perfect match with the original SRAM pulleys, ensures the shifting feel.
The RD base is 3D scanned, to make sure the contact parts are perfectly matched, leaving the RD stability intact.
Lower lotus tooth pulley, upper pulley maintains in the exact position as the SRAM original pulley, you can enjoy low friction resistance pedaling without having to worry about chain length or cassette compatibility.
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.
Second, the number of contact tooth or control tooth between chain and cogs of 17T is more during gear shifting, the more contact, the stronger the control power.
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.
