Pivoting Extension Arm for ASF-1, ASF-3

Park Tool Pivoting Extension Arm for ASF-1, ASF-3 adds a third, adjustable support point to the Park Tool Adjustable Support Frame system, making it easier to stabilize bikes and frames that don’t sit well in a traditional repair stand clamp. By extending up to 24" from the main crossbar and locking into one of five indexed positions, it helps dial in secure contact on non-standard frame shapes, long wheelbase bikes, and wide or awkward loads.

• 24" / 60cm Reach - Extends support farther from the crossbar to better cradle long or unusual frame layouts
• Five Locking Positions - Indexed adjustment helps place support exactly where the frame is strongest and most stable
• Improves Stability for Non-Standard Bikes - Helps support bikes that can be difficult to clamp securely, including cargo bikes and other unconventional geometries
• ASF System Compatibility - Designed for use with Park Tool ASF-1 and as part of the ASF-3 configuration
