Gravel
Titanium Gravel Bikes
Our gravel range is designed around fast off-road riding, long-distance utility and durability over demanding terrain. Stable handling, generous tyre clearance, practical mounting points and the natural damping of titanium come together in bikes that feel composed at speed, capable under load and confident when the terrain gets rough. Every complete bike is assembled to order in Australia, with the final specification, fit and setup guided by how and where you ride.
The range
Choose your gravel bike
Two titanium gravel platforms: one built for speed, one built for range. Mostly sealed roads with the odd gravel section? The Summit all-road bike takes tyres up to 42 mm.
Grit SS
Explore the Grit SS: Grit SSGravel performance, fully resolved. A faster, more focused titanium gravel platform: aerodynamically optimised tube profiles hold speed on the road, 3D-printed titanium junctions and fully integrated routing keep it clean, and rack, mudguard and fork mounts take it further on long mixed-surface routes.
Grit
Explore the Grit: GritBuilt for where the road ends. An adventure gravel platform with real range: clearance for 700c x 50 mm or 650b x 2.2" tyres, rack, fender, top tube and fork mounts for loaded bikepacking, routing for dynamo lighting and a dropper post, and a choice of fully integrated or semi-internal routing.

Questions
Questions about our gravel bikes
Grit or Grit SS?
Choose the Grit SS for speed: a faster, more focused platform that holds pace on sealed roads and hardpack and stays composed off-road. Choose the Grit for range: the most tyre clearance, mounts for loaded bikepacking and flexible routing for longer, rougher and more remote riding. We can help you decide in a complimentary consultation.
What tyre sizes fit?
The Grit takes tyres up to 700c x 50 mm or 650b x 2.2". The Grit SS has clearance for modern high-volume gravel tyres. Gravel Core Builds come with Pirelli Cinturato M gravel tyres on Bossi Nomad carbon wheels.
Can I fit racks, mudguards and bags?
Yes. Both bikes have rack and mudguard mounts and fork mounts. The Grit adds top tube mounts and multiple bottle positions for loaded bikepacking, plus routing for dynamo lighting and a dropper post.
Can I buy the frameset on its own?
Yes. Both are available as a frameset or as a complete Core Build. Framesets include the frame, carbon fork, carbon seatpost, headset, expansion plug, alloy spacers, thru-axles and seatpost clamp.
How long does a complete bike take?
Framesets are typically in stock and fulfilled within 48 hours. Complete bikes are assembled to order in Australia and usually ready in 2 to 4 weeks, depending on components and workshop scheduling. We confirm the timeline after you order.
What warranty comes with a Bossi frame?
Titanium frames carry a 50 year replacement warranty against manufacturing defects for the original owner, and carbon forks a 7 year warranty. Impacts, collisions and mistreatment are not covered. See our warranty for the full terms.
