With a footprint no larger than a traditional bicycle repair stand the PRS-30 easily lifts and lowers bikes up to 120 lbs. The professional-grade clamp lowers to a height of 29` allowing you to clamp onto the seatpost or seat tube of most bicycles without needing to lift them into the stand. Height adjustment is accomplished using an internally-geared mechanism driven by a simple hand crank. Height can also be adjusted using a common battery-operated drill with 10 mm socket for truly effortless lifting of heavy bicycles. Features sturdy legs with integrated wheels for easy repositioning
