Ventum GS1 bike review: A modern gravel race bike with aerodynamic considerations and generous clearances

As the gravel market continues to fracture into adventure vs race subcategories, the Ventum GS1 skews racey. It may be a thoroughbred, but it’s up for whatever you can throw at it

Ventum first made a splash in the world of triathlon with an unconventional, but aerodynamic design that eliminates the downtube of a traditional triangle frame. Since then, the company has ventured into the road and gravel bike markets, albeit with more typical frame designs. 

The company operates with a direct-to-consumer model, which means that it doesn’t sell bicycles at bicycle shops, and instead sells them directly to the end user. In theory, this allows the company to pass along some savings to the end user by eliminating a piece of pie normally eaten up by a brick and mortar bicycle shop or retailer.
