ASF-1 Adjustable Support Fixture
More info: parktool.com/ASF-1
The increasing popularity of bicycles with non-standard frame geometry presents a problem for mechanics looking to put these bikes into repair stands. Park Tool presents a solution.
The Park Tool ASF-1 replaces the clamp in any Park Tool Professional Repair Stand with a rotating crossbar and two adjustable-position 12"/30 cm support forks, which can be configured to accommodate a wide variety of bicycles with non-standard frame designs, including most "moto"-style e-bike frames.
The capabilities of the ASF-1 can be expanded using optional 24" support forks (ASF-24, sold separately) to better support wide loads such as trikes and front-loading cargo bikes.
Features:
• Crossbar width: 44.125" (112 cm)
• Maximum support fork width (outside-to-outside): 40.5" (103 cm)
• Minimum support fork width (outside-to-outside): 5.75" (15 cm)
• Fork length: 12" (30 cm)
