Greenfield's Stabilizer Rear-Mount Kickstand attaches to the rear chainstay of the bicycle so it's perfect for bikes that won't accept regular kickstands like mountain bikes. It comes complete with an extra-wide rubber foot for superior stability and won't interfere with pedal action or rear derailleur cables. This is the stand of choice for law enforcement bike patrols throughout the U.S. - Fits tube sizes up to 7/8" in diameter - Certified Non-Corrosive Casting - Snap Action Mechanism - 285mm (for bikes 22" and under)
