Optimize your bike maintenance with the versatile and innovative Park Tool ASF-1 Adjustable Support Fixture, designed exclusively for professional bicycle repair stands. Crafted with durable materials and engineered for superior performance, this adjustable fixture addresses the challenges of repairing bikes with non-standard and complex frame geometries-including modern "moto"-style e-bike frames, cargo bikes, and wide-load bicycles.

Performance & Engineering

The ASF-1's innovative design features a rotating 44.125 (112 cm) crossbar, allowing for flexible positioning and easy adjustments to accommodate various bike frames. The two independently adjustable 12" (30 cm) support forks provide a secure grip on non-traditional and wide frames, including especially difficult shapes like e-bikes, trikes, and cargo bikes.
