For gravel or city riding, the ACID pedal COMBO A9-CB offers the best of both worlds: the convenience of a grippy flat pedal on one side, and the security and efficiency of an SPD-compatible clip on the other. The compact aluminium cage features eight adjustable and replaceable pins for excellent outsole traction, whilst the clipless mechanism is stainless steel for durability and long-lasting good looks. And the CNC-machined, drilled out Cr-Mo axle runs on a combination of sealed cartridge and sealed industrial bearings for a long, trouble-free service life.
