Campa Ekar GT ProTech Crankset

The new Campagnolo Ekar GT Gravel crankset for the 1x13-speed Ekar drivetrain with ProTech - Ultra Torque axle technology.

The two aluminium cranks offer maximum efficiency and durability. A Q-factor of 151 mm ensures a comfortable and efficient pedalling style, regardless of your height. The single chainring with the Narrow Wide profile ensures clean chain guidance in all gears. The ProTech - Ultra Torque axle system was developed for gravel use. The new ProTech bottom brackets are significantly better sealed, making them ideal for off-road use. The Hirt screw connection reliably joins the two half-axles inside the bottom bracket. The stiffness values of this system are on a par with the best 30 mm axle systems. The stainless steel ball bearings are pre-mounted on the crank arms and are easy to replace if necessary.

Campagnolo ProTech:

The patented ProTech technology with double seals firmly connects the two axle halves within the bottom bracket and protects the bearings from the ingress of water and mud, ensuring high performance and durability even under the worst conditions. The innovative and proven Ultra-Torque technology has been further developed for gravel use. The Hirth spline of the ProTech system features self-centring and self-aligning teeth located at the centre of the crankset, where the ends of the integrated axle halves meet.

The axle halves are secured with a single, oversized, protected bolt. Their precise fit can even compensate for the misalignment that some carbon frames may exhibit due to the minute tolerance differences in their manufacture. The torque transmission of the ProTech crankset system is as efficient as that of a single thru-axle and lighter. Furthermore, it is also more durable, as it is better protected than other systems. The oversized stainless steel bearing located on the crank arm outside the bottom bracket cups offers maximum stiffness, smoothness and strength thanks to the increased diameter of the crank axles.

The ball bearings themselves are included with the Campagnolo Ekar cranks. Due to the wider design required for the new ProTech bearing seals, Campagnolo ProTech bottom brackets are not compatible with Ultra Torque road bike cranks

Campagnolo ProTech crankset bearings:

The stainless steel deep-groove ball bearings guarantee smooth running and are included with the crankset. The ProTech bearings feature sophisticated seals, making them suitable for off-road use

Campagnolo Ekar:

Lightweight and reliable, the Ekar gravel groupset from Campagnolo. Named after Mount Ekar, Campagnolo’s Ekar 13-speed groupset is no conventional groupset. With a wide range of gravel-specific combinations and without compromise, Ekar is designed from the ground up to deliver optimal performance, the best riding experience and maximum reliability for your gravel, all-road and endurance routes on the toughest terrain you face and where you want to challenge yourself. From the outset, our engineers and design team tested and pursued the idea of a 1x system, considering it the most suitable system for gravel, whilst taking on the challenge of creating the lightest, most efficient and most precise drivetrain for this type of use: the Ekar groupset.
