Anyone got a screw on Suntour Ultra 7 speed freewheel/cassette they no longer require? May take a 6 speed one but has to be ultra spacing.

Ultra is the 5mm spaced one that will fit on 126mm rear

Something with smallest cog in 12 or 13 and a larger inside cog preferred but let us know what you have (can always make the inner triple ring smaller)

Thanks

John

13/24 six speed. Looks narrower than 5mm. About 31mm total.

Will be 5.5mm or 5.0mm (looks like a new winner and they had std and ultra)

Can you post a pic of other side? Does last cog have an A on the back of it?

There is an A on the 24 but can’t see what’s on the 13. £25 posted if it’s any good to you. jm.

Ok aparently D dimension in photo below is supposed to be 30mm on a 6sp ultra and 36mm on wider spaced.

If possible to check that would be awesome as need the ultra spacing

Many thanks

John

Isn't that a hub measurement and not the freewheel. I thought the idea was to use a narrower chain and cogs closer together to pack in more gears into the same space?

Yeah but the measurement I got came straight off the Suntour brochure page.

Many thanks,

Found one on eBay that was similar price but was definitely a 5mm spaced one so meant there wasn’t a worry it wasn’t wrong size for build :)
