Spec from Specialized's then current US page (captured 2009-07; model year from the page header "2009 Hotrock Boys Models"). The family geometry table has one column per wheel size; this entry keeps the 24 inch column only. The page's tire row names a 20 inch wheel while the model name says 24. MSRP $370 read from the model's own row of the US MSRP list on its then current page, captured 2009-07 (inside the 2009 launch window). Colors: Gloss Charcoal/Candy Red; Gloss White/Black. Specialized published the same spec sheet for "Hotrock 24 Girls 21-Speed" in this model year (separate products by name).
