Power transfer begins at the pedals, and Shimano's Ultegra Pedals boast Pro Tour-proven tech to make the most of your riding. Composite bodies are light and extra wide, maximizing your efficiency and reducing power-stealing flex. Stainless steel tread plates improve pedal body durability for miles of faithful service. Additionally, adjustable entry and release tension lets you customize pedal performance to suit your riding style.

Shimano's Dura-Ace 11-speed Cassette is comprised of two aluminum cog carriers, 5 titanium and 6 steel cogs (from largest to smallest respectively). This makes for a super-light and stiff cassette for perfect shifting so you can dance up the climbs as easily and efficiently as your chain climbs up and down these cogs.

Garmin brings power to the pedal with the Vector 2. Built in conjunction with Look Keo pedals, the Vector offers precise power measurement in a rugged, ultra-convenient, discreet package. Garmin encased sensitive strain gauges inside the stainless steel pedal spindles for years of durability and accuracy to within +/- 2%. The Vector is essentially two separate power meters and measures power from both legs, meaning you have the data to correct discrepancies between your left and right sides. Now you can eke out those last few watts and maximize your pedaling economy. The robust Vector 2S pods are easy to mount, and have a status light indicating when they're on and pairing occurs. Switching the pedals and pods between bikes is blissfully hassle-free and takes less time than getting kitted up. The pedal bodies are built of tough, light carbon, while the battery/ANT+ pods hang protected beneath the crank arms. At a nimble 312 grams including pedal weight, the Vector is one of the lightest power meters available.
