Shimano 6700 Ultegra has long been recognized as a solid performer and thanks to Shimano’s Systems Engineering approach the 6700 series continues to deliver.
Lighter, more stylish and advanced by the latest Dura-Ace technologies, new Ultegra 6700 is a beautifully balanced groupset with optimal performance and specifications. Its unprecedented racing DNA takes shifting and braking to another level, with a with a weight reduction of 150 g versus 6600 series.

The new lever shape and ergonomics are a prominent feature of the new Ultegra 6700 Dual Control shift levers. Angled outward, the levers give the rider a head start on the arc of the shift with optimized hand placement, increasing comfort and efficiency. Ergonomics are further enhanced by a re-profiled perch that reduces overall reach and girth.

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.

The Shimano Hollowtech II technology continues as a bench mark in the crank and bottom bracket strength to weight category. The bearings are as far apart as possible, eliminating axle flex. Efficiency is also maximized because the bearings primarily carry radial loads resulting in lower overall friction and drag. The wider stance benefits bicycle manufacturers allowing extra real estate to fortify the bottom bracket area of the frame to keep flex to a minimum.

New Ultegra’s striking wide-link design main body creates rigid pivots that create a foundation for precise shifts through the rear changer. Additionally, the new body and cage design accommodates a 28 tooth large cog so the mountain stages can be attacked with confidence. The pulley cage design allows for the use of a short cage, even with a large 33T total capacity.

For the front changer the wide inner link with two anchored pivot points resists flex and moves the chain with authority. Combined with the new HollowGlide chainring, instant shifts under load require no more attention than any other shift.

Shifting precision and smoothness on the chain has been significantly improved through the use of different inner and outer plate chamfers and dimensions to accommodate the different shifting requirements of moving the chain inward and outward on the drivetrain.

For the rear cassette a more rigid aluminum carrier keeps the cogs in check when making shifts under load and each shift is lightning quick thanks to revised tooth profiles.

Groupsets do not include pedals, headset or hubs but these can all be ordered separately.
