如平把手(Flat handle bar)配的跑車中變應有專屬的型號，
但近來發現很多前輩們改車，都不是如此搭配(如使用105中變)，
這樣搭配上是否好用 ???

To address the growing demands of fitness minded cyclists we're introducing new components for road-sport bikes with straight handle bars. This group offers shift levers (SL-R440), front derailleurs (FD-R440/FD-R443) and brake levers (BL-R440) designed specifically for road-sport bikes with straight handle bars. Straight handle bars provide a more comfortable riding position and easier brake operation that allow more people to experience the fun and excitement of a lightweight road-sport bike.
