FULCRUM E-Fire 5 27.5´´ Disc Tubeless MTB wheel set 15 x 110 / 12 x 148 mm

Smooth,solid, precision steering. E-Fire 5 is a mix of technologies and quality in a model that aims to be an introduction tothe meaning of “specialist”, E-MTB specific and perfect for gravity. A confident gradual response to stress means even the most difficult obstacles can becleared easily and safely, enabling maximum concentration on riding right fromthe first few meters because reactions will always match the trail ahead. Choosing aE-MTB specific set means deciding to ride with technologies designed to improvethe dynamic behavior of your bike, pushing those boundaries and starting totruly race.

Differentiated Profile Delta For E-mtb: - The front and rear wheels of a mountain bike have two very distinct roles. While they both must must roll in an efficient manner the front wheel is tasked more with rideability and handling while the rear must carry more weight and transfer power from the drivetrain. The increased weight, added power and more extreme forces represented by the E-MTB only serve to make great design for the specific needs of each wheel all the more necessary. As a result, Fulcrum E-MTB wheels incorporate specific profiles for front and rear. The front rim is more rigid and aids in maneuverability while the rear rim (with lower in profile) is flatter and reinforced to deal with the larger impacts in a more efficient and comfortable manner. Asymmetrical: this is a well know solution for Fulcrum, and it is also confirmed for the E-Mtb project. The asymmetry makes it possible to leverage on the inclination and length of the spokes to optimise the forces coming from the cogset and from the disc brake during the braking operation. This makes it possible for all elements to work together and create the ideal balance. In-frame: - The wheels are the contact element with the ground, where the shocks from the ground first discharge. When the suspensions work at maximum capacity, the frame collects and distributes the stress, the system is subjected to really high forces.It is during jumps, when we go over potholes, or take bends at high-speed, during the most exiting moments, and the more thrilling downhills that we demand the most from our bike. The wheel-tyre system, in this respect, must guarantee stability during repeated stress. At the same time, our engineers certainly could not guarantee this by adding material: weight must always be low, to keep the ride pleasant and reactive. It was decided to develop an internal support architecture, a bridge insert positioned diagonally, so that it can counter the front shocks. By leveraging the structure geometry, the load is distributed on the whole rim, preventing thus excessive compression. The maximum result with the minimum weight load: this detail allowed a 10% side rigidity increase and a 14% increase on the vertical one, changing thus drastically the overall performance. Reinforced Head Spokes: - 13% more resistant. For the new E-Mtb Fulcrum range, only oversize spokes, with a specific reinforcement design on the heads, will be used: this makes it possible to have the best quality of response to stress both in terms of resistance and in terms of transfer of the propulsive power. The technical refinement does not stop here. Changes were made to the profile too, which in some versions is variable. An elaborate section, which varies from 2.2 mm of the head to 2/1.8mm in the thinnest point, makes it possible to save the very important grams without affecting performance. Reinforced Disc Flange: - 5% more rigid. A lot of speed and increased weight obviously affect the braking system just before approaching a bend. The disc flange become a fundamental part because it is the interface between the disc, where the callipers grip, and hub, which transfers to the rim the braking force. The new flange is thicker compared to the previous one. It is also 5% more rigid to ensure a robust support when braking. Reinforced Freehub System: - 4X more reliable. Attention to detail was also paid to the freewheel body system, which is the point of junction and transfer of the driving force from the cogset to the wheel body. The drastic increase of power and jerks, due to the intervention of the motor, made it necessary to use a freewheel body with tempered steel dedicated gears, which are able to withstand a breaking tension by 30% greater. The laboratory analysis observed the behaviour of the individual ratchets on cycles greater than one billion of uses: the carburised steel ensures an estimated lifetime that is 4 times longer compared to the Ergal model used for the non-E-Mtb models. Microspline Freehub: - We understand technical evolution as painstaking attention to product development, and it’s one of the cornerstones of all projects that come out of our R&D Department. The Fulcrum spirit entails a constant effort to pick up and seize on new trends and keep pace with the most advanced technologies available. This is why we adopted Shimano´s MICROSPLINE standard as soon as the new racing drivetrains for 12-speed mountain bikes were presented, and will introduce the ground-breaking technology throughout our range. The Shimano MICROSPLINE option will be available on all MTB and E-MTB wheels in the MY2020 catalogue. At the same time, it will be possible to convert all wheels in the Red Zone, Red Metal and Red Fire range and all previously purchased and used E-MTBs featuring different bodies using a conversion kit comprising body and pivot.
