Campagnolo EKAR 1x13 Speed Gravel Chainset On 11 November 1927, when Tullio Campagnolo found himself all alone at the foot of the first steep climbs of the Croce d’Aune, he was not afraid and did not give up. Now that today we can count on a whole crowd of friends along our path, keen fans and admirers of Campagnolo products, we will never give up. We have chosen this image from the turn of the century to trace the salient stages of our distant and recent history.Campagnolo is not just a company, a logo or a trademark. Campagnolo today can be described as a brand.An organization that has always transmitted and shared a set of values. Campagnolo has become all this in over 80 years, in part thanks to itself, the Campagnolo family, the individuals who every day dedicate all their efforts to a shared goal, but above all, the merit goes to keen cycling fans.Campagnolo EKAR 1x13 Speed Gravel Chainset The crankset is the heart of the new 1x Ekar system, with its optimised gearing ratios, sensitively spaced across a wide range.Of course, the single chainring is simple to use – no front mech, significantly reduced weight, fewer moving parts to collect dirt or clog, and providing high chain security, with no wasteful gearing overlap – perfect for gravel riding and racing.The unidirectional carbon fiber cranks feature a strong, durable 630-grade steel alloy crank axle – following the maxim of smartly mating strength and light weight that is employed across the Ekar groupset. New ProTech™ technology joins the two semi-axles inside the bottom bracket, with a single, oversized bolt.Oversized stainless steel bearing sit on the crank, fixed on the semi-axles, for maximum smoothness and strength – and easily accessible for inspection and maintenance without the requirement to extract the cups.There are four ring size option:-Adventure has 38 teeth-Pure Gravel is 40T-Fast Gravel is 42T-eGravel 44TTheir narrow-wide design provides efficient drive and maximum chain security.The light, strong 7075 aluminum rings are easily interchangeable – you can simply unbolt them from the four spider arms with no requirement for crank disassembly.The four arms, which are asymmetrically set for optimal spread of the torque load, feature a 123mm Bolt Circle Diameter. Swapping rings is an easy and efficient way to switch out your gearing as you tackle different types of riding.The Ekar crankset features four arm length options – 165, 170, 172.5 and 175mm – to suit riders of all sizes and styles.For some gravel bikes featuring low bottom bracket heights, shorter crank arms are a popular choice to avoid grounding on loose and unpredictable surfaces.A narrow 145.5mm Q-factor makes for a comfortable, efficient pedalling style, whatever your size.The UD carbon arms come with neat, removable protective end caps, to keep your components looking like new, whatever terrain you tackle.615 gr (172.5mm, 38T)FEATURES & BENEFITS

LIGHTNESS, RIGIDITY, SIMPLIFIED ASSEMBLY AND MAINTENANCE:ULTRA-TORQUE™.THIS IS CAMPAGNOLO'S ANSWER IN THE INTEGRATED CRANKSET SECTOR.AFTER MORE THAN 10 YEARS SINCE ITS INTRODUCTION THE ULTRA-TORQUE™ SYSTEM, IT IS STILL CONSIDERED, THE BEST PERFORMING CRANK-SET SPINDLE IN TERMS OF STIFFNESS, LOW WEIGHT AND EFFICIENCY OF POWER TRANSMISSION.Campagnolo found a way to permanently conjoin the semi-axles of the bottom bracket to the respective crankset arms. This redesign made it possible to considerably reduce the lateral dimensions at the axle level and prevent annoying contact with the ankles when turning the pedals.Assembly is simplistic: one single oversize bolt is enough to integrate the two semi-axles. With regard to torque transmission efficiency, this system is equally as effective as a single piece axle.Furthermore, despite the narrow side profile, we have been able to position the bearings outside the bottom bracket shell, resulting in greater axle rigidity from the increased axle diameter. This breakthrough was obtained by using an ingenious mechanical system derived from many years' motoring experience in the rotation axle and engine shaft coupling sector: the Hirth joint.In short , this is a joint with self-centring and self-aligning frontal teeth located in the middle of the bottom-bracketaxle where the ends of the semi-axles, integrated with the crankset arms, come into contact.Patented dual-sealing ProTech™ technology securely connects the two semi-axles inside the bottom bracket, and protects the BB bearings from ingress of water and mud, providing longevity of high performance, even in the worst riding conditions. A gravel-orientated development from Campagnolo's innovative and proven Ultra-Torque™ technology, the ProTech™ system's central Hirth joint features self-centring and self-aligning frontal teeth located in the middle of the crank where the ends of the integrated semi-axles meet.The axles are fixed together with a single, protected oversized bolt, their precise pairing can even overcome the fractional misalignment that some carbon frames can include thanks to the tiny differences in tolerance in their manufacture. The ProTech™ crank system's torque transmission is as efficient as a single piece axle, and it's lighter. And, being better protected than other systems, it is also more durable. Oversized stainless steel bearing sit on the crank, outside the BB shell, for maximum stiffness, smoothness and strength thanks to greater axle rigidity from the increased axle diameter.
