Unior BMX Freewheel Remover - 4-Pin, 24mm - Professional Workshop Tool

Art. No. 616066 | Ref. 1670.6 | 4-Notch BMX & Single Speed Freewheels | 1.370" x 24 TPI | Made in Slovenia

A professional-grade BMX freewheel remover from Unior - a Slovenian tool manufacturer trusted by professional bicycle mechanics and workshops worldwide. This 4-pin tool is designed specifically for removing 4-notch BMX freewheels and single-speed hub freewheels with the standard 1.370" x 24 TPI thread. The 24mm wrench flats allow use with a standard spanner, adjustable wrench, or socket. Unior tools are built to professional workshop standards - a significant step up from the budget removers that round out and fail on stubborn freewheels.

Key Features

• 4-pin engagement: Four prongs engage the notches of compatible BMX freewheels securely
• 24mm wrench flats: Use with a 24mm spanner, adjustable wrench, or appropriate socket
• Secure during removal: Retain the tool on the freewheel using the axle nut or quick release skewer while applying force - prevents the tool jumping off under load
• Professional quality: Unior manufacture to workshop/professional standards - hardened steel construction
• Made in Slovenia: Unior's tools are manufactured in their own factory in Zrece, Slovenia - not outsourced budget tooling

How to Use

Engage the 4 pins of the tool into the matching notches on the freewheel. Before applying any force, secure the tool in place by threading the axle nut or quick release skewer back through the axle - this prevents the tool from jumping out of the notches under the torque required to break the freewheel loose. Apply a 24mm spanner or adjustable wrench to the wrench flats and turn anti-clockwise (freewheels have a standard right-hand thread and unscrew anti-clockwise). Stubborn freewheels may require a breaker bar or length of pipe for additional leverage.

Compatibility

✓ COMPATIBLE WITH:

• BMX freewheels with 4 notches (the most common BMX freewheel standard)
• Single-speed and fixed-gear hub freewheels with 4-notch engagement and 1.370" x 24 TPI thread
• Many ACS, Shimano MF, Dicta, and other common BMX/single-speed freewheels

✗ NOT COMPATIBLE WITH:

• Shimano multi-speed cassettes - cassettes require a cassette lockring tool, not a freewheel remover
• Shimano/SRAM splined freewheels - those use a different tool (Unior 1670.1)
• Suntour-style freewheels - Suntour uses a different pin pattern (Unior 1670.2 or 1670.3)
• 2-notch BMX freewheels - check your freewheel has 4 notches before purchasing

Note: If you are unsure how many notches your freewheel has, look at the inner face of the freewheel where it threads onto the hub - you will see either 2 or 4 recessed notches. This tool is for 4-notch freewheels only.

Condition
