Lightweight, wide and tubeless ready

British-brand Parcours announced the addition of a 650B Alta gravel wheelset; a versatile offering for those seeking a ‘one wheel’ setup for their gravel bike. Performing at its very best off the beaten track, the lively and dynamic Alta 650B thrives on exploring the most rugged of trails, and yet is also just at home powering along the flats, with responsive handling and lightweight build. 

The 650B rim allows the support of wider gravel tires for greater grip and comfort without sacrificing clearance, and the lower pressure required for 650B tires also negates the need for the bead hook as on a road wheel, allowing for a lighter, stronger and more aerodynamic wheel profile. The Alta 650B is built with a hookless rim to offer a more robust rim design, well suited for the most animated off-road routes. 

The Alta 650B wheelset builds Parcours’ proven aerodynamic profile into a wide carbon rim, to provide the ultimate wheelset for fast all-road fun. The Alta 650B boasts a 35mm rim depth for speed and efficiency, alongside a wide internal rim width of 25mm. This allows the wheelset to work with the widest gravel tires. Combined, this helps to maximize comfort and traction over the toughest of terrains.  

The Alta 650B takes its proven rim profile and applies it to the smaller 650B size. Without the requirement for a braking surface, the disc brake rim profile has been designed for the optimal rim/tire interface. The precision-machined alloy hubs are fitted with high-grade EZO cartridge bearings to deliver smooth running in all conditions and use a Centerlock disc fitment.

The hubs are fitted for 12mm thru-axles front & rear, however, adapter kits are available for other axle standards. There is a 24-spoke 2-cross pattern front & rear to ensure the Alta 650B is robust enough for whatever is thrown at them. Despite the robust nature of the wheels, the Alta 650B comes in at only 1,360g for the wheelset, perfect for the off-road climb or getting quickly up to speed.

Dov Tate, founder of Parcours said “We’ve launched the new Alta 650B to allow our riders to ride further than they’ve been before. Its versatile nature encompasses the spirit of gravel riding, go anywhere and everywhere and enjoy yourself while you do it!”
