The Campagnolo Chorus EPS groupset takes a great deal of its DNA from its mechanical counterpart as it represents a more accessible version of Campagnolo performance, quality and attention to detail but delivers it in the laser-like precision package of an EPS drivetrain. It's extremely powerful motors are capable of producing levels of torque without rival in electronic shifting which guarantee precise and effective shifting no matter the conditions or circumstances. Shifting even under heavy load is no problem for the Chorus EPS transmission and mud, grime and debris have met their match against such powerful motors. With an IP67 waterproof rating on the entire system rain gear is only necessary for the cyclist, not his groupset. The dérailleur is composed of a mechanical structure with dropout and a series of electronic parts. The outer Dérailleur Rod held in place by a double-finned pin that passes all the way through to increase rigidity. The System that links the dérailleur to the frame is made of aluminium co-pressed with the engineering polymer of the body of the dérailleur. This creates optimal solidity and rigidity ensuring that the dérailleur maintains a correct position with respect to the frame. The core of the dérailleur is composed of an electronic actuator; in turn composed of a gear motor with a built-in resolver that uses Magnetic Hall Sensor technology (as the sensor is not in contact it is not affected by the vibrations generated by the terrain, and is therefore always precise). The gear motor was developed in partnership with a Swiss company that produces electric motors used in missions to Mars. The actuator is also equipped with a ""cascade gearbox"" which allows movement to be transferred in an exact and rapid manner. AUTOMATIC CORRECTION: Compared to the traditional mechanical derailleur that could be adjusted with micro displacements made by acting on the levers manually, the EPS dérailleur is equipped with a very sophisticated electronic AUTOMATIC POSITION CORRECTION system. DTI: Digital Tech Intelligence is housed inside the Power Unit and it continuously monitors the signals that arrive from all the EPS components, thus managing their operation. WATERPROOF: In order to achieve the IP67 classification, all the electronic components of the EPS system underwent a series of tests, which proved their ability to function perfectly under one meter of water for at least 30 minutes.

Auto Repositioning D.T.I.™ technology means that the EPS™ system knows the rear derailleur position and the selected sprocket at all times. In relation to this information, the system transmits a signal to the front derailleur, which fine-adjusts its position to maintain optimum alignment with the chain.

Our philosophy is all about having fun. We ride Mountain Bikes because we love the mountains and we want to enjoy ourselves on the best bikes available. Raze is the much anticipated, highly innovative trail bike from Mondraker combining the best of XC with the best of Enduro to create a bike without limits.Raze is the desire of a large part of the mountain biking community made real: lighter than a traditional Enduro bike but without sacrificing performance, yet lighter of foot and better at pedaling. The longer we spend riding in the mountains, the more the distinct disciplines of mountain bike are blurring. How far can we go with today’s latest generation of XC bikes before they merge into what we call Enduro? We all want the best. The total Mountain Bike, the “quiver killer”. "I don't want two bikes! I want one that can do it all and make me a better rider". A bike that adapts to all environments, to any type of use, which allows us to ride with our Cross Country whippet friends one weekend and then bang out some runs at the Bike Park with our downhill mates the next.When we debuted the Raze back in the summer at the Sölden Bike Park in Austria, even we were shocked by its performance. When you try it, it makes you rethink whether you really need anything more, or even whether you need different bikes for different rides. Raze really makes you rethink and question the boundaries between disciplines. Some will see it as that ideal bike "a little beyond" the traditional XC but without losing that XC racing performance. You can climb at the same rate as your XC mates but you’ll leave them for dead on the downs. Others will see it as that long-awaited mini-Foxy, with almost the exact same evolved geometry but which lets you ride farther, hit more jumps, rail more single-track and cover greater distances, faster. Too aggressive for XC? Incredibly light for Enduro? It’s all of that and more. Raze redefines what is and has been a traditional trail bike. Don't try to compare it to anything else because it’s got a unique identity and personality. If you’re lucky enough to try one, you won’t want anything else.With 150mm travel at the front and 130mm at the rear, the new Raze is not a normal trail bike. The definition of a trail bike isn’t based on suspension travel, but rather on functionality.In line with our philosophy mountain bikes are for fun, and to fulfill that objective they must be really, really good at going both up and down mountains. Raze is our new Trail model for those who want it all, and with guarantees. The Raze frame is manufactures from carbon fibre using our latest generation STEALTH AIR FULL CARBON technology, achieving a frame weight (not including the rear shock) of close to 2 kg. We have fully optimized our double-link ZERO SUSPENSION SYSTEM to achieve the best pedaling response and the most uncompromised suspension performance in a bike of these characteristics. Raze debuts a new lower link for optimal stiffness.With Trail-specific kinematics and a FOX shock tuned specifically for this model, we’ve managed to strike the perfect compromise between pedaling efficiency and overall performance. The key to the new Raze is that it has the best traits of both XC and Enduro all rolled into one single model: The best of F-Podium and the best of Foxy Carbon as a new generation of trail bike: Agile, with a lightning fast pedal response combined with surprising sensitivity and shock performance as well as, until now, unheard of levels of lightness, extreme maneuverability and enviable poise. Your next bike? Most likely.
