Bassi X Keystone Belmont Frameset

The Belmont arrives Spring 2025 in Montréal and Philly, and is available for pre-order. Please get in touch if you also want a build, we're full of good ideas!

Please purchase directly through Keystone Bicycle Co. if you're in the US.

The Belmont is an all-road, randonneuring, light-touring bicycle frame designed in collaboration between Bassi Bikes and our friends at Keystone Bicycle Co. based in Philadelphia, PA.

This all-new model combines our design and manufacturing knowledge at Bassi, and the KBC crew's long-distance randonneuring experience.

The result of our serendipitous joining of ideas and experiences is a versatile, capable and comfortable frame that'll be the perfect companion for many things involving paved and unpaved road, gravel, carrying much or little stuff, and so on. The sturdy construction, versatile design, time-tested standards and the tough E.D.-coating and finish make for a frame that, with a little care and attention, will treat you well for many, many years. It's the kind of frame that can take on lots of different configurations and evolve as your needs do, too.

For the full backstory on developing the Belmont, check out our introductory blog posts here and here!

Stock complete builds will be available soon. If you'd like just the frame, we'll gladly install any in-stock headset, bottom bracket or other parts for free when combined with our Frame Prep Labour.
