Gran Sasso 29" MTB Bike

Tommaso is excited to offer our first mountain bike ever! Our riders have been requesting a mountain bike for years, so we created the Gran Sasso. This entry to mid-level mountain bike is perfect forclimbing mountains, cruising dirt and gravel with ease, and taking on rough terrain. No matter where you want to go, the Gran Sasso can take you there in comfort and style with rugged components meant to withstand the abuses of off-road terrain riding.




The Tommaso 29" Alloy MTB frame is rack ready for all your bikepacking and commuting needs, while SR Suntour SF15-XCM fork offers 100mm of travel to crush your local trails.



A full Shimano drivetrain provides a huge range of gearing options with a convenient heads up display on the shifters. Shifting is smooth and consistent with on demand power and performance.



Mingda alloy rims provide exceptional strength and durability, so you can tackle the trails, mountains, and streets in confidence.
