我想败这东西
Strengths: Shimano Airlines is a semi automatic shifting system which shifts as fast as you can push the levers. Precise shifts requiring hardly any mechanical force to shift. At the end of a long run when you are toast, you can go from flat out and shift all 7 gears very quickly without much effort. It shifts in the air much better then cables. Extremely bullet proof rear derailleur is much more durable then anything else. Shift levers are more adjustable then others allowing a custom fit, if properly adjusted you don't open your grip as much on the handlebar when shifting. Airlines never goes out of adjustment because of cable stretching.
Weaknesses: Cold temperatures and high altitude effect shifting performanc.If running bottle on the downtube do not for get to put the valve cap on because high speeds{50mph) pushes the valve stem in releasing all the air in the tank.
