The Hammer S line of 29er, 130mm trail bikes, are engineered in Germany to be super-light, but tough enough to handle everything you throw at them. With a smart geometry-adjusting headset, you can swap in your 27.5 wheels and keep the same geometry, for even burlier ride days. All bikes in the range feature Rockshox front and rear suspension, Syncros dropper posts, Shimano hydro brakes and SRAM's excellent Eagle 12 speed drive trains
