ROATA SPATE FULCRUM E-METAL 3 29 2WF-R 6 BOLTS BOOST SHIMANO HG

The E-Metal 3 wheelset by Fulcrum has been specifically designed for trail riding adventures on the 29“ e-mountain bike with boost standard. It guarantees stability and smoothness, while at the same time offering easy handling when tackling and clearing any obstacle, whether uphill or downhill. Trail-Riding Pro: The E-Metal 5 E-MTB wheelset from Fulcrum The choices made during design all had precise objectives in sight: exceptional ease of handling and confident response in any condition. E-Metal 29 has a lightning response to stress thanks to the record-breaking stiffness of its rim-spoke-hub set-up, to the total advantage of transmission speed from the handlebar controls and pedals to the ground. This is made possible thanks to a higher and more directional wheel designed specifically for the front, and a rear end one reinforced thanks to “In-frame” technology and ready to provide maximum power transmission. When you set out to tackle a single track at top speed, pushing yourself to the limit for your best ride, your only reaction will be amazement. It all happens in an instant. A few seconds are all it takes and everything becomes the pleasure of riding, automatically, instantly. Features - Fulcrum E-Metal 3 29" Boost Convertible to tubeless system thanks to 2-Way-Fit Ready technology In-frame technology distributes the load evenly over the entire rim, thus avoiding excessive compression Spokes with reinforced head guarantee high resistance and perfect power transmission The inner width of 30mm makes it possible to mount plus-tyres up to 2.8"Product features Use: Trail, Enduro Model: E-Metal 3 Wheel size: 29" Rim height front: 23mm Rim height rear: 18mm Rim width: 35mm Inner width: 30mm Rim type: Clincher Tubeless system: Yes, convertible Recommended tyre width: 2.0 to 2.8" Brake Type: Disc Brake Disc brake standard: 6 bolts Over Locknut front: 15 x 110mm Boost Over Locknut rear: 12 x 148mm Boost Bearings: Sealed cartridge bearings, adjustable Spokes: front 28 / rear 28 Weight limit: 150kg (rider, bike, equipment and luggage)Technologies Asymmetric Rim The asymmetry is designed to improve rim tension, balancing the forces from brakes and sprocket cassette. 2-WAY FIT™ The wheelset can be converted into a tubeless system. The conversion is only permitted for certain types of tyres. For more information, visit the Fulcrum website. 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. 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. The wheel-tyre system, in this respect, must guarantee stability during repeated stress. This is why Fulcrum developed 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. SPECIFIC NIPPLE HOUSING The nipples and their housing are one of the most important element that are taken into account during the design of a wheel. During the development of the new E-Mtb Fulcrum rims, a lot of work was put into this aspect. The housing has been re-designed and now it makes it possible to eliminate completely the nipples' hard work. Thanks to a special housing, with side guides on both sides, the nipple sets on a stable base, perfectly in position, oriented towards the spoke. This makes it possible to make the distribution of the tensions in the rim more even, creating thus perceptible benefits in terms of effort and rigidity: this prevents misalignments under stress and, as a consequence, deformation to the structure. REINFORCED HEAD SPOKES 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 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 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 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 Fulcrum adopted Shimano's MICROSPLINE standard as soon as the new racing drivetrains for 12-speed mountain bikes were presented.
