Spec from Specialized's then current US page (captured 2012-10; model year from the part numbers shared with the 2013 archive page of this build). The family geometry table (6-SPD Boy, 6-SPD Girl) is shared by several models and does not name this model's column, so sizes and geometry are left empty. No size list on the captured pages. MSRP $360 read from the product's own MSRP block on its then current US page, captured 2012-10 (inside the 2013 launch window). Colors: BLUE/WHITE/BLACK; WHITE/RED/BLACK. Also captured as: Hotrock 20 6-speed Boys. Specialized published the same spec sheet for "Hotrock 20 6-speed Girls" in this model year (separate products by name). Carryover: Specialized part numbers B4E0-4109, B4E0-4709 also appear on the 2014 entry specialized-hotrock-20-6-speed-boys-2014 (the same part numbers in both model years; kept as separate model year entries, as Specialized labels them).
