The tig team s.l. mountain frame, something that I have been building for at least 16 years pretty much in this form. Only stuff that you wouldn't find on the 1993 edition would be the bigger headtube and the disc brake fittings. The wishbone stays , headtube gussetts and machining are much the same as back in the day. I was hoping to build a 25th anniversary mtn. frame last year but there was no time. I guess I'll have to wait until the 30th anniversary !
