Shimano Ultegra RD-6700A-GS Rear Derailleur

Shimano's 6700 Ultegra group set the standard for performance value in 10 speed drivetrains and was the last it's level to feature a triple ring crankset option. The RD-6700A-GS Rear Derailleur was developed to accommodate a standard or compact triple crankset with an 11-30 cassette for a wide-ranging, closely spaced set of gear options. The wider link design allowed the mid-length cage derailleur to prevent the chain torsion and deflection of the extreme gear options.

Ultegra means quality construction, impeccable function, durability, and complete reliability, even with the massive range and chain of angles of triple drivetrains. A stiffer, wide outer link design suppresses flex for sharp, precise shifts that are faster, smoother and more stable at any angle. The 4 fluorine-coated link pivot pins minimize friction and increase shifting response. A note on the 11T pulley wheels: Shimano essentially used the 6600 11T pulley wheels because the triple drivetrain was developed using the non-directional 1st generation CN-6601 10 speed chain. If you run a double chainring setup with an 11-30 cassette with this RD-6700A-GS Rear Derailleur you can use the CN-6701 directional chain with no issues. That chain will not shift properly with triple chainrings. The pulley wheels will work with both. If you are looking for a 10 speed Shimano rear derailleur with wide ranging capacity, this Ultegra RD-6700A- GS is the best one ever made.
