2025 · 700c wheels · 5 sizes

Italian-made Dedacciai steel drop-bar adventure frame, sold by Mason as the ISO 2 and updated for 2025 with a T47 bottom bracket and the HotShoe2 carbon fork. It uses Boost 148 x 12 rear and 110 x 15 front spacing and runs either 29 x 2.4 or 27.5 x 2.8 wheels and tyres. Numbers here are for the 29 inch option: stand-over and trail are Mason's 29 x 2.4 figures, and Mason publishes stand-over in centimetres, measured vertically 50 mm in front of the bottom bracket centre. The 58cm frame has a steeper 70 degree head angle than the smaller sizes.
