Like most good ideas, the Scorpion MTB Stand is a relatively simple, straightforward tool that's sure to make your life a lot easier. This minimalist stand helps you perform simple repairs to your favorite mountain bike without taking up the space of a traditional bike stand. It attaches to the hollow spindle of your bike's crank arm, supporting your bike with the rear tire elevated off the ground. This makes gear adjustments and other maintenance work much easier. It's also super-light and portable enough for race day, weighing in at just four pounds. The Scorpion MTB Stand comes with an adaptor to fit most hollow cranks, such as Shimano, SRAM, Rotor/FSA, Specialized, Truvativ, and Cannondale. Moreover, it works with 26, 27. 5, and 29-inch wheels for compatibility with your favorite XC, trail, and enduro bikes.
