The XT is partial coverage fairing that works on a lot of different bikes and trikes, and typically mounts on the front derailleur mast. Since it is a small fairing, it doesn't provide as much aerodynamic assistance as the larger, full coverage fairings. On bikes/trikes with low seats and limited forward visibility, it's sometimes the only fairing that will work. In spite of its small size, it's great at keeping your feet warm if you're a cold weather rider. W=18" H=19" Depth=7.5" L=22" To determine if this is the right fairing for your bike please see the Fit Chart.
