Usefully it also incorporates a braze - on type front derailleur mount , so extending the gear range shouldn ' t be a problem 同時上面也貼心的預(yù)留前變速器組裝位置,在未來升級時不會有任何問題。
Using a 9 - speed chain with 8 - speed front derailleur and crankset will result in sluggish shifting and the adjustment is more critical 使用9速鏈條搭配8速前撥及牙盤會導(dǎo)致遲緩的變速并使調(diào)整過程更加困難。
The 8 - speed chain is too wide for 9 speed front derailleur ; the chain will rub during cross shifting ( large / mid ring / large cog ) 8速鏈條對于9速前撥來說太寬了;在進(jìn)行“交叉變速”時鏈條會產(chǎn)生摩擦(大/中齒盤對大飛輪) 。
