The teeth of the Record(tm) sprocket set have an Ultra·Drive(tm) design that integrates the chain and chainwheels of the crankset to ensure fast, precise and consistent shifting through the years.
Titanium version = Maximum weight savings.
Aluminium carrier for the largest sprockets = Precision, rigidity and weight savings.
Sprocket synchronization = Fast precise shifting, less stress for the chain.
Ultra-Drive(tm) machining of the teeth = Chain passage optimization.
Splines only fit 9/10-speed hubs and wheels.
Only 11t models include Lockring.
