Installation

Threads on clockwise and tightens under pedalling. Removal needs a proper freewheel tool (Park FR-1.3 or Shimano TL-FW30) turned anti-clockwise — they can be stubborn once they’ve been on a while.

FAQs

Is this for 6-speed only? Yes — it is a 6-speed freewheel. For 7-speed see the MF-TZ500 or MF-TZ510 7-speed models.

Cassette or freewheel? Freewheel. Screw-on only; will not fit a cassette freehub.

UK availability? Widely used replacement part for older UK hybrid and city bikes.

Typical UK RRP sits around £24.99–£29.99. A proper Shimano part that shifts more cleanly and lasts longer than cheap no-name alternatives.
