Mavic Ksyrium Pro wheelset review£675.00

Familiar wheels get a little wider

BikeRadar score4/5

Built with all in-house components including Mavic’s low-maintenance hubs and wide Zicral alloy spokes (18 front, 20 rear with an offset for more even tensions), these wheels feature a wider rim than previous Ksyriums. Said rim uses the company’s ‘4D’ milling process to produce a beautifully sculpted profile.

Despite the extra width (and undrilled rim), these aren’t approved for tubeless. Like most of its wheels, these come with Mavic’s own-brand tyres.

The Pros weigh 864g for the 26mm-deep rear and 654g for the 24mm-deep front, plus 124g for the skewers. The 25mm Yksion tyres average 213g each, and measure just over their nominal width on rims that are 21.8mm externally and 16.7 internally. The tubes are 128g each and our GP4000S II comes up at 26.5mm wide.

Mavic should be commended for finally offering a wider Ksyrium, but we wish it had gone even bigger. The familiar Ksyrium feel remains largely unchanged: these are slightly firm riding – likely in part because of the large cross-section alloy spokes – but are very stiff and with a snappy feel.

Heavier, more powerful riders will love them as they offer an outstanding stiffness-to-weight ratio; lighter riders may prefer softer-riding options. For blasting up climbs in style though, these are very fine wheels.
