ULTEGRA Dual Control Levers ST-6700 feature composite lever blades and cable routing underneath the handlebar tape.

The Dual-Pivot caliper brakes feature new compound brake shoes just like the new DURA-ACE 7900 series. They offer doubled brake performance in wet conditions and improve stopping power also in dry conditions by 20%. The brake calipers have been developed with an enhanced brake arch proportion for an increased linear response. The new caliper construction ensures an improved cable routing (especially with sloping frames) and reduced cable friction. The brakes feature a spring tension adjuster and adjustable toe-in brake shoes. Weight is 317g per set.
