Get your older bike back on the road. Shimano's MF-TZ20 6-Speed Freewheel is an economical replacement part for vintage bikes with worn out drivetrains. A smart selection of gearing options allow you to tackle any terrain, in the city and beyond.

The MF-TZ20 6-Speed Freewheel is compatible with 6/7/8-speed chains and older hubs which accept thread-on freewheels. These are common on road bikes from the 1980's and earlier and some newer children's and dept. store bikes. This part is not compatible with modern splined freehubs which accept cassettes.

Gearing Options:

  • 14-28T
  • 14-34T

Shimano 6-speed freewheel simple, reliable, flexible, works great.

There's a reason Shimano, while often frowned upon for it's dominance, continues to dominate. They make solid stuff that works. I chose this 6-speed freewheel with the extra low low-gear because of its simplicity, flexibility, and reliability. Sure enough, it works like a charm. I'd never used Western Bike Works before and experienced my usual nervousness entrust my credit card number to a bunch of strangers. No worries! The freewheel arrived quickly, the price was right, all is well.
