Ready to take your ride to the next level, the SPEED 55T Carbon Road Wheelset is the work of intense research carried out by Fulcrum. Deploying their new AC3 technology to give both the look and use an upgrade, the full-carbon rim benefits from a different braking rim and has an elastic responsiveness certain to give you the upper hand on your rivals. Perfect for sprinters, power transfers are enhanced for nothing but pure speed, while the aerodynamic wheels maintain energy ready for deployment when it matters most.
Just as capable on the triathlon scene, the 55T utilises a flywheel effect created by the rim rotation, optimising support to help acceleration whether on the flat or climbing short hills.
Front Hub: Carbon, Aluminium flanges
Rear Hub: Aluminium, Aluminium oversize flange
Freewheel: Plasma treated HG freewheel
Front Spokes: 18, Left 9 - Right 9
Rear Spokes: 21, Two-To-One, Left 7 - Right 14
Axle: Front Axle Compatibility: QR; Rear Axle Compatibility: QR, Aluminium
Using high-end ceramic balls, which perform continually thanks to the absence of lubricating grease and the precise machining of the cup and cone technology, the friction is reduced drastically and in turn increases the smoothness of triathlon and road bike wheels by as much as 9 times compared to standard bearings.
Every push on the pedals from the rider will force most of that energy on the drive side of the rear wheel. To combat this loss of rim tension and power transfer, Fulcrum has solved this cycling problem with their 2:1 spoke ratio pattern by doubling the spoke count in crucial zones on the wheel.
An exclusive rim/spoke mounting system. It allows the rim, spokes, hub and nipples to align perfectly, guaranteeing the precise spoke tension in all areas around the wheel.
Featuring no holes on the central section of the rim means that the rim is uniform at every point, free from critical areas subject to stress. The advantages are immediately clear: less weight, longer lasting rims, greater resistance to fatigue, the possibility of giving the spokes more tension and more stiffness which, in terms of performance, means improved responsiveness and acceleration.
AC3 enables surprising braking performance, which is very noticeable in difficult weather conditions. Rather than using the traditional machined brake track approach, Fulcrum uses micro laser incisions on the brake track surface to remove resins and create a smooth surface. Lab tests have shown that this process improves braking power by an improvement of 6%. However, in the wet this performance increase jumps to 43%. Bringing braking in the wet closer to the performance experienced when riding in dry conditions.
The freehub body has been Plasma treated, which makes the aluminium especially hard and resistant to surface abrasion and wear. This means the thickness of materials used can be to be reduced to a minimum, achieving a lighter weight, while maintaining lifespan and reliability.
