Fulcrum SHARQ GR:

The GR project emerged from a comprehensive analysis of race data and extensive experience gained from international gravel competitions. The goal was clear: to develop a wheel that supports high speeds on rough terrain, offering greater control, precision and a measurable aerodynamic advantage. At the heart of the project is the new 2-Wave rim with a 30 mm rim width and mini-hook, which works perfectly with wide tyres. It optimises their shape, contact patch and stability. The variable rim profile with a height of 47/52 mm optimises airflow, reduces crosswind sensitivity and minimises aerodynamic drag. The Sharq GR is Fulcrum’s highest-performance gravel race model: FF100 carbon fibre, hubs with cup-and-cone bearings, flat A3RO spokes and a 2:1 lacing pattern for maximum responsiveness, precision and aerodynamic benefits. Total weight: 1,550 g. Perfectly matched to modern 47–50 mm gravel tyres.

Fulcrum Sharq 47-52 Carbon Way Fit rims

The 2-Wave rim profile features a regular symmetrical wave that transitions into an asymmetrical wave at the flanks. The profile height varies between 57 and 62 millimetres from the lowest to the highest part of the wave. With this design, Fulcrum achieves an optimal balance between low aerodynamic drag and stable handling in crosswinds. Compared to a conventional profile of the same height, wind tunnel tests showed a 21 per cent improvement in crosswind stability at approach angles between 0° and 10°, and up to 30 per cent at approach angles between 10° and 20°. 2-Way Fit technology was developed to guarantee perfect compatibility of tubeless rims with standard clincher tyres and inner tubes. 2-Way Fit wheels are particularly versatile and therefore perfectly suited to any situation.

Mini Hooked / Crotchet tubeless TC:

‘Hook’ or ‘Crotchet’ refers to the shape of the rim flange, which features a so-called hook. This supports the tyre bead and ensures reliable performance, even when using high tyre pressure (> 5 bar). ‘Tubeless’ means that the rim can be ridden without an inner tube, but a setup with an inner tube is also possible.

Cone & Cup ball bearings:

Fulcrum and Campagnolo rely on classic ball bearings with ball rings, cones and bearing cups for their high-quality wheelsets. These continue to offer the best smooth-running properties. The classic deep-groove ball bearings are easy to adjust, clean and maintain.
