An alliance has been formed between IRC (Inoyue Rubber Company) of Japan and Yeti Cycles of USA. Previously the majority of IRC manufactured tires sold in the USA have been sold under the Avocet and Ritchey brand names, Yeti may now be added to the list. The 26 x 2.125" For Racing Only is made in Japan with a Kevlar bead and is at this time (January 2, 1993) available only with a Black sidewall which is really exposed tire casing, since the casing is made from Black rubberized casing fabric. The tire tread design is made of eight rows of tread blocks which make one 3.77" tread pattern. Down the center are two 6 by 15mm parallelogram shaped blocks whose direction changes from horizontal to vertical, left to right facing as it moves through four variations within the pattern. There are two edge tread blocks on each side of the tire between the parallelogram blocks. They are based on an abstract of a triangle. Because of how the tread repeats itself, it has no suggested forward rotation. The tread rubber tested to a relatively soft 62/A hardness.
