Spindly brake calipers can’t effectively stop a speeding bike. The new Ultegra 6700 brakes not only have a rigid caliper to slow the wheel, but also a cam in the levers that provides mechanical advantage and modulation. With new pad compounds, the braking power is 20% better in the dry and has actually doubled in wet conditions. By conserving energy expended in stopping and modulating, riders can simply go faster, and longer.

Features:

• New super SLR design: Enhanced brake arch pivot location for quick linear response
• Low profile outer cable stop: Improves cable routing for reduced friction especially with sloping frame
• New brake shoe compound: 100% more stopping power in wet conditions.
• Spring tension adjuster: Allows customized spring tension for equalized lever pressure
• More ergonomic brake system: Better controllability
• Adjustable toe-in brake shoes
