Fulcrum Komplet kotača Racing Zero C17 2025

The Fulcrum Racing Zero C17 wheelset is a best-in-class alloy clincher road wheelset that balances lightweight, durability and performance incredibly well. It is the gold standard among high-level aluminum wheels, now improved with a wider rim. Despite weighing just 1495 grams, it feels fast and responsive on the road and still boast class-leading strength and durability thanks to the triple-milled rim construction. There is a slight difference in depth between the front and rear rim, that helps to reduce system weight and increases the lateral stiffness of the rear wheel, helping to deliver power directly from rider to road. With a rim diameter of 22.5mm, the Fulcrum Racing Zero C17 can accommodate tires up to 50mm, which helps to increase grip and comfort over rougher surfaces. The front hub's shell is constructed from carbon to reduce system weight, while the high-flange rear hub is made of alloy to increase torsional stiffness. Both hubs have USB ceramic bearing, which promise a reduction in rolling resistance and an increase in durability. These high-quality hubs are laced to the rims via 16 alloy spokes on the front, and 21 on the rear which maximizes aerodynamic performance and wheel strength. As an added bonus, these alloy spokes are easy and economical to replace. The Patented technical solutions, the materials used and the wheel geometries make it the ideal partner for competition. Race after race, Zero wheels have become synonymous with excellence, quality, performance, reliability… and victory!

Compatible with  9/10/11 speed Shimano and Sram transmition system!

Features:

• Lightweight triple-milled alloy rim - makes it possible to reduce the peripheral weight of the rim and to increase the reactivity of the wheel
• Tire type: clincher
• Brake surface: alloy
• Differentiated rim height with 27mm at the front for good handling and 30mm at the rear to transfer all the power to the wheel
• Internal width: 22.5 mm, ETRTO 17C
• Tyre width: from 25 mm to 50 mm
• Compatible with rim brakes and cantilever brakes
• High precision processing of the rim allows to obtain a perfectly even structure and to remove tension areas in the rim
• Spokes: Aero, Straight Pull
• Number of spokes: 16 front / 21 rear
• Aluminum aero straight pull spokes provide a precise choice to ensure optimal rigidity and a special attention to aerodynamics
• Aluminium nipples with light weight reduce the peripheral mass, enemy of reactivity
• The lightweight carbon fiber QR front hub and durable oversize aluminum QR rear flange provide an innovative mix that provides excellent torsional rigidity and consequently a greater reactivity. Greater reactivity to each change in pedalling tempo and more efficient power transmission to the wheel
