If you haven't been able to get past the nagging voice in your head telling you that Mavic wheels are falling behind the times with their narrow rim widths, you can end your tumultuous inner dialog now. Sure, the French brand is big on tradition, but not at the expense of rider safety and better designs. Making changes only when it had the technology ready, Mavic released the Ksyrium Pro Clincher Wheelset with a 17mm internal rim width, a full 2mm wider than its predecessors, to give it a better fit with 23mm and 25mm tires. Lean into a swooping corner on a narrow descent without scrubbing speed, confident that the tires' improved stance on the rim will give you the grip you need.Aside from the widened rim, the beloved shaped of the Ksyrium Pro returns this year, complete with the deliberate construction of Mavic's Inter Spoke Milling 4 Dimensions ISM 4D process. The process eliminates excess material to capitalize on Maxtal aluminum's efficient blend of lightness and strength, delivering a wheelset that will see you through seasons of regular training miles on smooth tarmac, windy summits, and neglected back roads, remaining responsive and reliable through it all.Run 23mm tires on the Ksyrium Pro if you must, but Mavic ships the wheelset with its 25mm Yksion Pro tires, which are far more than just an attention grabbing add on. Like the eloquent servers at your favorite restaurant, Mavic takes wheel tire integration seriously, giving wheel and tire selections all the attention given to your entree and wine pairings. The Yksion Pro tires are each optimized for front and rear use, with the GripLink delivering traction and flat resistance up front, and the PowerLink rear providing low rolling resistance.
