昨天在GCN的節目看到的
比較有意思的是在Muc Off的實驗室測出來
Shimano 11速的『鏈條』比12速的速度快上36.6%
L.O.P.S 2.0 was designed, developed, tested, and hand-built in the UK for Shimano Dura-Ace RD 9100 and Shimano Dura-Ace RD9150 11-speed rear derailleurs. Why 11-speed only? Our in-house testing found 11-speed chains to be on average 36.6% faster than 12-speed; and L.O.P.S 2.0 is all about speed!
