The Feedback Sports Scorpion Bike Stand 2-piece takes an already efficient and simple bike stand solution, and makes it even more compact and portable than before. The Scorpion 2-piece works exactly like the standard Scorpion, but can be taken apart to lay flat, making it the perfect work stand to throw in your car for race day with its low profile, portable design. Like the standard Scorpion, the Scorpion 2 piece works by sliding into the center of nearly any hollow crankset, elevating your rear wheel for easy cleaning or derailleur adjustments. It comes with three different sleeves for cranks with 20mm, 18mm, and 13mm diameters. The sleeves lock into place with a convenient push-button to prevent them from sliding off when you're removing your bike, but keep in mind that this stand must be run with a crank-sleeve to prevent the button from catching on the inside of your crankset. The Scorpion 2-piece bike stand comes in at only 4lbs, and packs down to just an inch and a half tall when it's disassembled. It works with any wheelsize, and just about any hollow crank. To check if your crank is compatible you first need to ensure that you have a hollow spindle crank with a minimum opening of 13mm on either the drive-side or non-drive-side. The Scorpion is not compatible with Capagnolo Ultra-Torque cranks with internal hardware, or non-hollow spindle cranks.
