Costing AU$6,920, the Grit SS frameset will ship from March 2024.<\/p>
The price includes the titanium frame, carbon fork, carbon seatpost (with zero or 20mm offset), headset, expansion plug, thru-axles and seatpost clamp. An integrated Bossi cockpit is sold separately for AU$800.\u00a0<\/p>

Building up the frameset with your preferred parts should be straightforward. – Bossi<\/figcaption><\/figure>Elsewhere, Bossi uses common component standards, such as a T47 bottom bracket<\/a> and 27.2mm seatpost, making the frameset compatible with a wide array of components.\u00a0<\/p>Bossi says the 1.5in head tube is compatible with most brands\u2019 integrated cockpits as well as its own options.\u00a0<\/p>

The Grit SS is Bossi’s performance-focused gravel frameset. – Bossi<\/figcaption><\/figure>Bossi says the Grit SS frame weighs 150g less than the Grit SX in size 54, tipping the scales at 1.7kg.<\/p>
It also claims to have improved the aerodynamics, but hasn\u2019t tested this in a wind tunnel.\u00a0<\/p>
The frame and fork are peppered with mounts for mudguards<\/a>, racks<\/a> and bikepacking bags<\/a>. There is clearance for 700x50c gravel tyres<\/a>.\u00a0<\/p>Other frameset features include:<\/p>

Geometry changes should sharpen the handling. – Bossi<\/figcaption><\/figure>Bossi says the Grit SS features \u201crefined geometry for a tighter, more responsive ride\u201d.<\/p>
Shorter chainstays, thanks to the new 3D-printed yoke, increase chainring clearance without cutting tyre clearance, according to the brand.\u00a0<\/p>
In addition, Bossi has slightly increased bottom-bracket height and decreased stack height. It says these changes enhance agility without making the Grit SS too aggressive to ride all day.\u00a0<\/p>
The Bossi Grit SS is available in 50cm, 52cm, 54cm, 56cm, 58cm and 60cm frame sizes.\u00a0<\/p>
Meanwhile, the Bossi cockpit comes in two wider and shallower \u2018Adventure\u2019 sizes (420x100mm and 440x100mm). There are two more aggressive \u2018Race\u2019 options: 415x110mm and 435x120mm.<\/p>
