Rocky's new Thunderbolt is billed as 27.5 inches of flat out fun. The XC tuned Smoothlink design is said to deliver exceptional climbing traction and stable pedaling platform. A 142mm E-Thru rear axle increases stiffness, internal cable routing keeps cables neatly stowed, “Stealth” dropper-post routing tucks the housing inside the frame, and the BB92 pressfit bottom bracket provides maximum lateral stiffness. The 770 model shown here comes in at 27.9 pounds.
