DESCRIPTION

Named after one of the most massive peaks in all of Italy, the Gran Sasso was developed for riders who want to climb rocks and shred dirt at an affordable price and unbeatable value. To do this, we start off with our insanely durable hydroform mountain series frame and SR Suntour suspension fork to soak up the rocks and bumps you’ll fly past on this 29er. We know that the trails require fast thinking, as well as quick braking, so we designed the Gran Sasso frame with a special flex eliminating bar, so that the Shimano hydraulic disc brakes can do their job and keep you safe ride after ride. Obstacles are part of trail riding, but they are no match for our bombproof 29er wheels and beefy tires, which roll over everything with ease. Go ahead, ride this beast of a bike with confidence, and enjoy the fresh mountain air.

The Gran Sasso, like every Tommaso bike, is backed by a LIFETIME frame and fork warranty, 14 Day Test Ride, and USA-based customer service to give you confidence that we will always be there to support you.
