As one of the most popular mountain bikes ever, the iconic Blast explodes this year with some fine-touch improvements and an overall upgrade in components. Using Superplastic formed tubing and smooth welds we create a frame that's super responsive, light and incredibly strong. This year's Blast comes with a beefier RockShox Tora fork with lockout, Shimano cranks and hydraulic disc brakes, WTB Valcon saddle, and 9-speed cassette for maximum terrain adaptability. This, good friends, is your ticket to good times.
