Brompton derailleur chain tensioner idler (jockey wheel) bearings / fixings set(pair)
The jockey wheels on the chain tensioner are made of a durable carbon composite material.
Over time these will wear and could help cause the chain to slip when under load.
기존 풀리보다 소음발생이 현저히 줄어듭니다.
순정풀리보다 부드럽게 변속됩니다.
Use ENDURO bearings.
변속향상을 위해 체인텐셔너 어셈블리 (텐셔너+베어링풀리)를 교체하는것이 일반적이지만
약간의 비용을 절약하기 위해 기존 풀리에서 베어링풀리를 교체하는것만으로도 향샹된 변속감을 느낄수 있습니다.
