COMPLETELY NEW DESIGN
The new shape of the external components enables the rear derailleur to move according to a different angle and the new internal design keeps the chain nearer the cassette to ensure better power transmission, greater and more secure traction, a better chain/sprocket interface and greater durability of components subject to wear and tear.
The special chainring positioned inside the gear body acts on a rectangular section spring that allows the component to move along a trajectory that perfectly follows the curve of the sprockets, on both the 11-23 cassette and the new 11-29.
ALUMINUM FIXING BOLT
The new two-part system is 53% lighter than steel and 22% lighter than titanium, without compromising resistance and rigidity levels and prolonging component life.
CARBON FIBRE UPPER AND LOWER BODY Extreme rigidity and reduced weight. It increases rear derailleur precision and prolongs the life of component.
CARBON FIBER CAGE PLATE
Shifting positioning is exceedingly precise - extremely light.
CARBON FIBER PARALLELOGRAM, AND EXCLUSIVE ULTRA-SHIFT(TM) GEOMETRY Maximum shifting rigidity, fast actuation, precision, friction reduction
CERAMIC BALL BEARINGS
Very smooth, reduces friction, prolongs life and shifting performance.
PULLEY CAGE ALUMINUM FIXING BOLTS Lighter.
What are derailleurs and mechs?
Derailleurs and mechs are two names for the same thing – the parts of your drive train that move the chain between chainrings for the front derailleur/mech and between the cassette cogs for the rear derailleur/mech.
Who needs a derailleur or mech?
Not all bikes have derailleurs, but if your bike has conventional gearing rather than singlespeed or hub gears, you will have at least a rear derailleur. These parts are exposed and somewhat vulnerable to damage, so you may need to replace them if this happens.
What are the choices?
Your choice will largely depend on what is compatible with the rest of your drivetrain, but there are different options for road and mountain bike, by the big three manufacturers, Shimano, SRAM and Campagnolo.
What should I buy with them?
If you’re replacing a front or rear mech, you may need to replace some other parts of your drivetrain as well, for compatibility or because you want them to wear together. These might include the chainrings, rear cassette or chain.
It’s not just compatibility with your other components you need to consider with a mech replacement. Derailleurs also have different fittings for various frame compatibilities, including braze-on fittings and a bolt-on collar.
