Mavic Zxellium SLR Ti Road Pedals. When it comes to maximizing performance and minimizing weight the Mavic Zxellium SLR Ti road pedals are in a class all their own. Weighing in at a scant 155 gramspair, Mavic has took full advantage of their technological know how to deliver a featherweight performer that ensures superb power transfer and simple entry and exit. The weight is kept low courtesy of a carbon fiber body, a carbon fiber spring blade, plus a hollow titanium axle. The Zxellium SLR Ti pedals sport a large, 700 mm platform area, however, to ensure all those mega watts you generate go directly to forward propulsion. Ten degrees of float and a low, 13.5mm stack height ensure your pedaling ergonomics, too, are dialed to perfection.
