Mechanism
Manual hook-and-fulcrum lever
Identify the component material first
The manufacturer’s steel-only restriction comes before the dimensional fit check.
What this choice changes
An adjustable manual lever restricted to steel
The FFS-2 is a manual lever for the steel frames, forks and components named by Park Tool. Its adjustable hook accepts tubes up to 44 mm, with 203 mm of sliding adjustment and a 750 mm overall length. Those dimensions describe reach and contact arrangement, not a diagnosis of whether a component is repairable.
Vinyl covers the hook and fulcrum pad. Choose the support and contact only within the approved component procedure; coated contacts are not a guarantee against finish marks. The tool is an adjustment lever, not a calibrated instrument that measures how much correction a particular frame needs.
The material restriction is decisive: Park Tool limits the tool to steel and warns against its use on aluminum or carbon components. A tube fitting the hook does not override that restriction. No frame-support fixture or repair assessment is included with the lever.

Questions before you choose
Can it be used on aluminum if the tube fits?
No. The exact maker restriction is steel only; tube diameter does not override material limits.
Does the tool measure misalignment?
It is an adjustment lever. No calibrated diagnostic-measurement function is established.
Are a stand or frame fixture included?
No supporting fixture is itemized. The supplied item is the lever.
