The Shimano Tiagra RD-4700 10spd Rear Derailleur brings functional, dependable, and precise shifting to a wider audience. Featuring cascading technology that's made its way down from the Dura Ace product line, the new Tiagra 4700 groupset has been completely redesigned to deliver the kind of shifting that thousands of riders have come to expect from Shimano.
With the RD-4700 rear derailleur, the redesigned body brings with it brand new smooth-spinning jockey wheels and bearings, as well as the lighter shift action borrowed directly from the Dura-Ace 9000 groupset. While these improvements make the shift experience that much better, Shimano has made sure to keep the rugged durability and adjustability that the Tiagra groupset has been known for.

10 Speed Ultegra is getting hard to find, so I bought this to replace an older Ultegra derailleur that was damaged when a chain broke on our tandem. Using the same Ultegra 6700 shifters, I think this newer Tiagra kit works even better than the old 6700 derailleur ever did! This might not be the solution you are looking for if you are a road racer weight weenie looking for those marginal gains, but I wouldn't hesitate to put it on any touring, commuter, or cyclocross bike!
The derailleur works fine and was in good condition out of the box. The hardest part of the job was installing a new shifter cable in the handlebar assembly ! Now I know how it's done !
