The Firma 27.5+ | 29

Our hardtail 27.5+ | 29er hard tail frame, the Firma is built with a chainstay yoke made from 6Al/4V titanium plate that strongly resists lateral and torsional forces in the rear triangle, yet allows a small degree of movement in the vertical plane. This small flex gives the bike excellent rear-wheel traction over bumpy terrain, and a smooth ride that holds off fatigue at the end of a long day in the saddle. The geometry is designed to make the bike fast and agile, yet stable enough to hold a difficult line.
