Mosaic AR-2 (All-Road Frameset)
New for 2026: the AR-2 replaces the GT-2 AR.
The AR-2 is Mosaic's all-road titanium frameset, batch built in Boulder, Colorado from hand-selected straight-gauge titanium with size-specific diameters and wall thicknesses. Short chainstays and a steep head tube angle mirror road geometry, while a lower bottom bracket, longer wheelbase and 40mm tire clearance take it well into the dirt.

- 12x100 / 12x142 thru-axles
