Carbon Body for Light Weight The XPRESSO 7 is an excellent value as it is the only pedal in the XPRESSO line to use a carbon body. The hollow steel axle is light and durable at the same time. The Iclic system is a pre-opened design, making clipping in super easy. The XPRESSO 7 features carbon blade tension adjustment, a low stack height, and an oversized platform for pedalling efficiency and comfort.
