Overview
About this bike
Rocky Mountain's Thunderbolt 770 MSL is the bike for when XC gets rowdy. Every rider loves a light, efficient bike, and the Thunderbolt is certainly that thanks to a Smoothwall Carbon frame with Smoothlink rear suspension and its pro parts spec. But it's so much more than an XC race bike with its relatively slack head angle, 120mm of plush Fox travel front and rear, and quick yet with big time rollability 27.5-inch wheels. The Thunderbolt takes to the air easily, wheelies like Evil Knievel, and rolls over chunder like the boss that it is. Those specs we talked about? How about Stan's tubeless wheels and XT/XTR gearing with XT discs? Not enough? Fine. A Race Face cockpit and cranks, as well as Maxxis rubber maximize the ups, and perhaps more importantly, the downs as well. Now, let's get rowdy.
