The Pivot Trailcat LT builds around a Hollow Core carbon frame with a flip chip that lets us adjust bottom bracket height and head tube angle without a shop visit. Toolshed storage keeps a tube and multitool inside the downtube, while a separate Tool Dock system mounts additional gear under the top tube and frame underside, so a repair kit doesn't have to compete with a water bottle for space. What Our Gearhead(R) Experts Are Saying:"I expected to miss wireless shifting the first time I got back on wired Di2, and I didn't. Shimano's XT Di2 fires the same shift every time, rain or mud, without a battery to check on the derailleur itself."
