Spec from GT's official 2011 catalog (PDF), specification chart on PDF page 150, column "STOMPER / SCAMP 20""; the catalog prints no prices. The chart gives one column for "STOMPER / SCAMP 20""; the same spec is entered for each named model. Fix round 2026-10-21: every row of this column re-read with a third reader (pdftotext -table, which keeps each row label level with its cells); values that the earlier two reader pass merged with a neighbouring column or dropped are now as printed. GT's chart prints this column's tire row as "Kenda ATB Dual Purpose, 24 x 1.95", the 24 inch column's tire, while its size row reads "20 INCH WHEEL" and its frame row "for 20 inch wheels"; the tire is left empty and the wheel size (20) is taken from the size and frame rows. Frame: GT 6061 MTB frame with water bottel braze-ons, for 20 inch wheels Bottom bracket: 3-Piece Square Taper Chain: 7-speed Uniglide Headset: Aheadset Sealed Mech Pedals: High Impact Nylon Platform Grips: Dual Density ATB Seat clamp: Aluminum QR Nipples: Brass CP MSRP $295 read from the product's own price block (under the model name) on GT's 2011 site product page "Stomper 20 - Ano White", captured 2011-04, inside the 2011 launch window (fix round 2026-10-21).
