Park Tool ASF-3 Pivot Ext Arm For ASF-1

The Park Tool ASF-3 Pivoting Extension Arm is a repair stand accessory designed for mechanics working with bicycles that have non-standard frame geometry, integrated bottom brackets, low-slung frames, or other configurations that cannot be adequately supported from a standard clamp position. The ASF-3 installs onto the ASF-1 Adjustable Support Fixture (sold separately) and adds an articulating extension arm that reaches up to 24 inches from the ASF-1 main crossbar, locking into one of five angle positions. Once installed, the ASF-1 support forks or ASF-24 can be mounted to the extension arm, enabling under-frame support where conventional clamping is not possible. The ASF-3 is compatible with the ASF-1 system and is not intended for use with the ASF-2 Clamp Adapter Add-On. Made in the USA with domestic and foreign components, it is part of Park Tool's expanding Adjustable Support Fixture accessory ecosystem.
