DetailsThe cage made entirely of aluminum alloy exploits the Z-Shape of the inner plate to permit immediate and precise shifting. The system is more rigid thanks to the use of the M-brace derailleur body while its life has been increased by the anti-friction treatment of the surfaces. Ultra-Shift front derailleurs are more rigid while thanks to the new chain guide fork the operating speed and ease of use and adjustment are enhanced. Furthermore, the anti-friction treatment extends their lifetime. The fastening system has also been redesigned in the clamp versions for improved compatibility with the bicycle frame.
upper to lower pulley-axle: 55 mm - composite outer plate - parallelogram with 11s geometry - black anodized forged aluminium upper body - lightened special rubber pulleys FEATURES & BENEFITS
REAR DERAILLEUR FIXING BOLTS IN ALUMINIUM: with the same resistance and stiffness, the new two-part system makes it possible to reduce the weight by 53% compared to steel and 22% compared to titanium ? prolongs the component life.
CARBON FIBRE FRONT PLATE: the body of the front plate wraps the upper and lower parts, providing 150% more torsional stiffness compared to a traditional rear derailleur.
ULTRA-SHIFT™ EXCLUSIVE GEOMETRY PARALLELOGRAM: maximum derailleur stiffness, fast shifting, precision, reduction of possible play
ULTRA-SHIFT™ ALUMINUM LOWER AND UPPER BODY: lower weight ? rigidity ? friction reduction - longer component life.
Cage plate with holes for reducing weight: lighter weight
