Spec from Rocky Mountain's 2007 model page on bikes.com (web.archive.org capture 2007-02). Frame: RMB CUSTOM 6061-T6 ALUMINUM. Colors: Black + Red. Front derailleur: SHIMANO C102. Maker menu group: KIDS. The geometry table on this page has 10 labels for 11 value rows, one of them empty; with the empty row set aside the rows match the labels, so head and seat angles and wheelbase are stored. The model name says 20 inch wheels but the page lists KENDA 24X1.95" tires, so the wheel size is left unknown. Speeds from the count at the end of the cassette code (TZ-31-7).
