Fulcrum E-Fire 5 Disc 6-bolt Boost 27.5″ Wheelset – 2019

E-Fire 5 Disc 6-bolt Boost 27.5″ wheelset by Fulcrum – smooth and precise
The Fulcrum E-Fire 5 Boost in 27.5″ is the perfect wheelset for your E-MTB. It has been specially designed for the requirements of motorized trail riding. On an MTB, the front and rear wheels perform different yet complementary functions. Thus, the front wheel influences the steering more and absorbs lateral shocks. The rear wheel carries most of the weight, which is amplified on an E-MTB with a motor. In addition, greater forces also act on the wheel due to the drive. The solution: Fulcrum developed the E-Fire 5 with asymmetrical rim depth. In the process, the front profile was made higher and stiffer, while the rear was lower and reinforced to better distribute ground shocks. The asymmetry makes it possible to use the inclination and length of the spokes to optimise the forces coming from the cassette and those coming from the disc brake during braking.
Guidelines for Replacing E-bike Components:Before you replace components on your e-bike, please read through the guidelines for component replacement for CE-marked e-bikes/pedelecs with pedal assistance.

If the necessary accessories (valve, rim tape and tyre sealant) are used, the wheelset is tubeless compatible. This makes it particularly versatile and perfectly suited for every situation. An Abrupt loss of air is prevented with this system – which is a clear plus in terms of safety. There is also less snake bite danger, as there is no tube that can be damaged.
What about a flat tyre? Don’t worry! One of the advantages of the Fulcrum 2-Way Fit Ready system is the possibility of removing the tubeless valve and inserting a normal tube to get you home.

Asymmetric Rim
Rim asymmetry is designed to improve the tension of the rim while balancing the forces coming from the brakes and cassette.

Anti-Rotation System™
Fulcrum’s technicians have redesigned the spokes and hub shells to create a strong and solid unit. In this way, the spokes never lose their initial tension, keeping the wheel perfectly reactive and centred, and the wheel remains in the position developed in the wind tunnel to ensure the best possible aerodynamics.
