Shimano Ultegra BR6600 Although Ultegra shares it's engineering lineage with Dura-Ace, it offers a new level of performance with a sleek design and greatly enhanced feel, giving Ultegra it's own unique identity.
Lightweight, compact, and durable, the Dual-Pivot design creates a tighter tolerance that gives the BR6600 firm and instantaneous braking response. Setting your own braking preference is a breeze with easier toe-in adjustment, thanks to an integrated convex washer on the fixing bolt of the pad.
You cannot match the more affordable Ultegra, with double AND triple options available.
* Compact & lightweight design
* Improved brake shoe durability
* Adjustable brake shoes for more or less modulation
