1. Downshifts in that range were sometimes abrupt, though the shifts were smooth in general. 在该转速区域降档的时候稍有顿挫感,但总体换档非常顺畅。
2. The brakes scrub off plenty of speed and the transmission executes perfect, rev-matched downshifts. 刹车能够有效的减速,并且变速箱也配合的非常完美。
3. In the worst case, some 8-speed chain rings have shown a tendency for "chain jamming" during downshifts with a 9 speed chain. 最糟的是,某些8速的齿盘在搭配9速链条进行减档变速时会有“跳链”的倾向。
