Shimano 105 5700 Bicycle Rear Derailleur

I have had two sets of these derailleurs. The shifting performance is good, but not perfect. It is easily adjustable to fine tune the shifting kinks. My issue with this derailleur is that it is not very durable. I've had one last 2,500 miles and another 3,000 miles. I have had both Tiagra and Ultegra derailleurs last me longer. In both cases, the bushings/bearings in the assembly that attaches to the hanger have worn out. When they wear out, the shifting performance and adjustability go down the drain. For my money, I'd jump up to the Ultegra. It has better shifting performance and lasts longer.

This derailleur provides quick, smooth shifting even when hammering the pedals. No skipping or crunching and instantaneous shifts which makes this derailleur a great choice.

Bought this to replace a beat up derailleur that had a few too many miles in it. Works beautifully, and at only a bit heavier than its Ultegra "big brother" it would be a worthy component in any Shimano drivetrain. Great also because as an amateur racer it's not only about what you can afford, but what you can afford to replace.
