My guess is no. I think someone would have figured that out by now if it could be done. That would save all our track problems. The real problem seems to be the width.
I did read where a guy did an extension with ovation rails. Still had to find a 12" track though.
the timbersled mountain horse snow bike kit is using a 12" wide track from camoplast, maybe theres some hope for you guys since theres a market for them now. I believe its a 121.
