FS: 3 TA criterium rings I just dug out of the basement! $25 plus shipping for the set. 56, 53 and 51 Teeth. If Beryl Burton could push them you can too! Actually in very good shape but they have surface corrosion that needs a vigorous polishing.
Joe Bender-Zanoni Leonard's driveway may be the steepest in Ann Arbor!
