Receiving interface
Older SunTour two-notch freewheels
Choose by the fitting
Compare the actual two-notch interface with the tool. Do not substitute FR-3 merely because it is also sold for SunTour.
What this choice changes
Match the older two-notch SunTour fitting
The FR-2 is relevant when an older SunTour freewheel has the two-notch receiving fitting. The two projecting contacts are the starting point for the choice. A SunTour name on the bicycle does not establish that this is the right tool: the FR-3 addresses a different four-notch system.
Park Tool lists an approximate 25 mm outside contact and 10 mm central axle clearance. The heat-treated alloy-steel remover is driven through its one-inch base using an appropriate separate wrench, socket or vise arrangement. Check both the freewheel fitting and the actual axle access; the drive size is not the freewheel’s engagement dimension.

Allow for the separate drive
The remover supplies the contact with the freewheel. Your suitable driving and retaining arrangements are separate from the one-tool offer.
Fit checks & limits
- The source expressly excludes the four-to-six-notch freewheel types from this tool’s recommendation.
- Demonstration axle hardware and the driving wrench are not established as supplied.
Questions before you choose
How do I choose between FR-2 and FR-3?
Identify the actual receiving pattern. FR-2 is the two-notch tool; FR-3 is the documented four-notch tool. The brand name by itself does not select between them.
Is the one-inch base the size of the freewheel fitting?
No. It describes the external driving interface. The separate two-notch contact and axle clearance must also match the job.
