KINDA DEEP THOUGHT OF THE DAY Simplicity is key when it comes to, well, just about everything in life. Especially bike stands. Its Slide-Lock clamp offers quarter-turn action, so getting bikes in and out of the stand is quick and easy. The stand has an adjustable work height of 42 to 71 inches, and the clutch allows for 360 degrees of rotation. The polypropylene molded jaws ensure that your seatpost and tubes will stay pristine. The Pro Classic also features a solid tripod that guarantees a stable platform on uneven surfaces, and it will support bikes up to 85lb (including tandems and DH rigs). The Pro Classic requires no tools for set-up and folds up into a compact, 12lb package to offer you the most convenient way to work on your bike in any location.FEATURES Material: anodized aluminum Clamp Opening: 19-48 mm Clamp Height: 1067-1803 mm Base Diameter: 1448 mm Load Capacity: 85 lb
