Shimano 6Sp Screw on Freewheel MF Z012 or 600

Postby Rob74 » Wed Aug 21, 2013 7:49 pm

Suggestions on Replacement options for whole wide spaced 6sp SIS screw-on freelwheel or donor cogs for insertion? ie 3.7m spacers

I have
wide spaced 6sp SIS screw-on freelwheel Japanese Shimano MF Z012 =>> 14-24
or
wide spaced 6sp SIS screw-on freelwheel Japanese Shimano 600 =>> 12-23

=>> If you can find them you can disassemble the "Singapore Shimano MF Z012's" to acquire cogs to replace damaged ones in Japanese Shimano MF Z012's.

The NEW Chinese made Shimano MF-TZ20 6-Speed Freewheel is
rubbish and typically 14-28 so turns a 52 42 front ring retro road bike with down tube shifters into a double shuffle bike.......that is not a great option.

Sunrace option kinda looks okay.
Sunrace 1 =>> 13-28
Sunrace 2 =>> 13-25
=>> Not sure if you can disassemble them for donor cogs? Anyone know?

NOS Japanese Shimano MF Z012's 14-24 or Shimano 600's 12-23 come up on occasion but $XXXY.

Thoughts?

I've got a couple of 6 speed Z012's in the shed, they don't look too used, so might suit what you want. Probably 12 or 13 - 25 or so. I'll take a look.
