At a guess I would say they are Veloceraptors with a smaller closer spaced treads as nano is a term for smaller. If so maybe aimed at a more hardpack or dry surface where mud clearance is less of an issue. Beyond that I know nothing
These are mentioned in the 2001 fisher catalogue - not with red walls though...the black wall ones had exactly the sameness script/typeface wilderness trail bike on the walls. This puts your as 20ish years old.
thanks guys ..... in fact this is also what I know .... red wall or rustwall ... never seen like you but that's obviously there, they seem to be very rare :shock:
I also got a response from Jason Rico - Red sidewall would have been a custom OEM spec for a bike company.We used to do a lot of that as bike brands at around the turn of the century.
that's it :idea:
