Overview
The Tommaso Gran Sasso is an alloy hardtail mountain bike with 29er wheels, a 24-speed Shimano drivetrain, Shimano M315 hydraulic disc brakes and a Suntour SF15-XCM fork with 100mm of travel.
It ships unassembled, and the frame's lifetime warranty is only valid after professional tuning at a bike shop, a detail more than one buyer learned only after purchase. The 680mm handlebar and 29-inch wheel clearance are aimed at riders who want climbing traction and control rather than a beginner-tier build.

Who it's for
