I want to build a fixed gear stumpjumper '91.
I found very old posts (10 years old or so) not only here but on other forums as well about disc mounted cogs.
People in those posts wonder if they are safe to use. i wonder, 10 years after, if those are still around (being used by people) and people still going on them, as I found some online still up for sale.
(for people that are not sure what Im talking about, these are cogs used to convert a disc brake wheels into fixed gear)
cheers
