SS (Standard or Spooled) Rear Stand Supports:

• Universally supports bikes with or without swingarm spools
• One side has a "V" shaped fork for easily locating and lifting a bike via swingarm spools
• Opposite side has a padded prong and vertical tab to support bikes from the swingarm itself (bikes without spools) 
• Comes in handy at the track if a spool mount is broken off in a crash, or if you have bikes needing two different support systems
