※ 引述《chienjr (Rincon LXT)》之铭言：
: 如所述，调整时要调到刚刚好不会与飞轮磨到....
: 可是，shimano的是可以上下弹的，也是这样调吗？
: 调太开会有什麽影响啊？
: 变速会变笨吗XD
太开的话变速会迟缓吧,哪天我自己试试
定义
B-screw: A screw used to adjust the spring tension
on the mounting pivot, which affects the distance between
the cogs and the guide pulley
症状
If the shift performance is poor in several outer cogs
but good in all the inner cogs, it may indicate that
the B-screw or chain length needs adjustment.
以上摘自Barnet's Manual chap. 32,这里面提到太多B-screw了,可以自行翻阅
另外不可以透过B-Screw调整链条张力,但这是适用Sram的後变,$himano的调整还是要看
它本身的说明
Do not use the b-adjust screw to adjust
the rear derailleur to act as a chaintensioning
device or to prevent chain
suck. This increases the chain gap
causing poor shifting performance.
