    Grit SX - Titanium Gravel Bike

    Our goal in designing the Grit SX was to create a gravel bike that is ‘more’ in every area. Better handling, more clearance, easier service, more versatility, more fun. The Grit SX is a complete overhaul of its predecessor with a raft of new features and reworked geometry. We have loaded the SX with everything that we'd want from a gravel/adventure bike in a package that is both tighter and more focused than the original Grit.

    The build options outlined above serve to provide estimated costs only. We have access to a diverse selection of groupset and components. If you don't find the exact build you're looking for, feel free to reach out, and we'll be happy to provide a tailored quote. Whether you're seeking guidance on your custom build or have questions about our designs, use the link below to schedule a consultation. We're here to address all your inquiries.


    We are fortunate to have stock of road and gravel groupsets from Shimano, SRAM, and Campagnolo. Groupset stock is limited, first come first serve. If your prefered components are in stock we can realistically build your bike in as little as two weeks.

    All our bikes are custom built meaning no two are ever the same. Assembling our bikes in house enables us to maintain our strict quality control for each and every build whilst delivering a personalised product for individual customer needs.
