Campagnolo Super Record EPS 12-Speed Rear Derailleur

##Campagnolo Super Record EPS 12-Speed Rear Derailleur The Super Record EPS 12-Speed Rear Derailleur uses a heady mix of titanium; aluminium; ultra-light techno-polymer and long-fibre carbon to produce Campagnolo?s top flight model. Improved; high torque motors enable quicker shifting under load; and allow the chain to be moved across the entire cassette in just one movement; whilst also allowing the use of cassettes up to 32 teeth in size. The stronger spring used reduces chain slap; and the improved chain wrap increases both system life and shifting precision. Both jockey wheels have undergone significant changes; with the upper one gaining longer teeth and an increase in diameter for improved accuracy of shifts whilst the shorter teeth of the lower pulley allows for more extreme chain angles and quietens the drivetrain.
