Campagnolo Shamal Ultra C17 Wheels

Shamal™ Ultra™ has always been the benchmark among the best aluminium wheels. Shamal™ Ultra™ features a wider profile to further improve two crucial aspects that have made this wheel the market benchmark: responsiveness and handling. The wider profile, combined with Campagnolo expertise, has delivered a 3% improvement in responsiveness and a 5% improvement in handling. Its exceptionally low weight delivers a unique feel on the bike: fast, responsive and extremely smooth-rolling. Shamal™ Ultra™ is available in clincher and 2-Way Fit™ versions, allowing you to choose your preferred tyre and get the most out of your rides.

KEY BENEFITS

Always the best

• USB bearings make Shamal Ultra an extremely smooth-rolling wheel

• The carbon hub bodies considerably reduce weight and deliver excellent lateral stiffness while reducing overall weight

• The distinctive G3 spoke pattern ensures optimal power transfer while reducing stress

Guaranteed performance over time

• The aerodynamic aluminium spokes, self-locking nipples and spoke anti-rotation system are designed to ensure maximum wheel performance over time

• The differentiated rim depths and hub diameters make Shamal Ultra an extremely light wheel without compromising performance

Suitable for every preference

• The clincher version ensures ease of use and greater convenience in the event of a puncture

• The 2-Way Fit version is designed for those who prefer tubeless tyres, with smoother rolling and more race-oriented characteristics

KEY FEATURES

TOROIDAL MILLING: reduces the rim's peripheral weight, making the wheel extremely responsive.

DYNAMIC BALANCE™

2-WAY FIT™ PROFILE: allows you to choose between a conventional clincher tyre and an innovative tubeless tyre.

ULTRA-FIT™: easy tyre fitting - maximum safety - less friction.

MOMAG™: allows the outer rim profile to remain free of holes.

DIFFERENTIATED DEL RIM DEPTH, ANT. (24 - 27 mm) - REAR (27 - 30 mm): rim dimensions optimised to achieve the best weight and stiffness for each wheel.
The section is lowered by 3 mm away from the nipple area to reduce weight and improve wheel responsiveness and handling.

SPOKES ANTI-ROTATION SYSTEM™: keeps the spokes in their most aerodynamic position.

SELF-LOCKING NIPPLES: maintain ideal spoke tension over time, eliminating friction against the rim.
This all helps maintain high performance throughout the product's life.

EXCLUSIVE MEGA-G3™ SPOKE PATTERN: perfectly balanced spoke tension on the 2 sides of the wheel. Reduces stress and increases lateral stiffness and power transfer to the wheel. Mega-G3™ eliminates vibration even with heavier riders.

AERO SPOKES IN ALUMINIUM: maximum aerodynamic efficiency - lower weight and greater responsiveness.

HUBS CON BALLS IN CERAMIC USB™: reduced friction, smoother rolling and lasting performance.

HUB BODY IN CARBON: high lateral stiffness - minimises weight.

AXLE IN ALUMINIUM: reduces wheel weight.

REAR HUB CON OVERSIZED FLANGE: increases torsional stiffness, improving responsiveness whenever the rider changes pace.

DIFFERENTIATED DEL HUB DIAMETER TRA FRONT AND REAR: ensures the perfect balance between low weight and mechanical stress.

2-WAY FIT

Founded in Vicenza in 1933 by Tullio Campagnolo, Campagnolo is still based in the Italian city and makes groupsets and wheels for road and gravel bikes. Its history also includes the wheel quick release, a mechanism the company refined to allow the wheel to be removed without tools.
