The Series One was our first frame back in 2000! It was a straight-forward, clean BMX frame that helped redefine what was necessary and what wasn’t. Twenty-one years later, The Series One is a high-quality complete bike that rides well and is priced to sell, with everything riders need and nothing they don’t. With three TopTube sizes and proportional components, there’s an S1 for anyone looking for a 20” BMX bike. Responsive but stable geometry, traditional fork off-set, and comfortable 2-pc bars, these bikes work for any style of riding. One glance at these in person will have you wondering if you’ve hung the wrong price tag on them.FRAME: 20.25” TT (SM) Cro-Mo Top & Down Tubes.GEOMETRY: Series One.HEADSET: A-Headset.BB: Sealed Mid.BARS: 2-Piece 8.7”x 29”.FORK: 33mm Offset Cro-Mo Steerer Tube.STEM: FIT Top Load.GRIPS: FIT Longtech.SEAT: New More Padded Integrated Combo.CRANKS: Tubular Cro-Mo 160mm.SPROCKET: FIT Key 25T.PEDALS: FIT Mack-PC.FRONT WHEEL: FIT S1W w/Unsealed Hub.REAR WHEEL: FIT S1W w/Sealed 9T Cassette.TIRES: FIT OEM 2.4”.BRAKES: New U-Brake w/more tire clearance and softer pull springs.
