A speed sensor designed into a quick release lever; this was, and remains, Mavic's signature computer feature. It's great Mavic finally souped up the rest of the system and created the Wintech Ultimate. Everyone loved the cable- and zip-tie-free look, it was just that the computer wasn't the equal of the genius design of that integrated sensor lever. We remember seeing people riding the first-generation computer with a Polar heart rate monitor strapped to the bars while the sleek Mavic computer sat cleanly on the stem.
