The CHASE RSP 4.0 boasts the same Olympic and World Championship geometry that Chase Pro Riders Connor Fields and Joris Daudet race, but features a plethora of technical upgrades. Chase has added enclosed dropouts with integrated 10mm (3/8″) chain tensioner system*, an integrated 1-1/8″-1.5″ tapered head tube, and a press Fit BB86 Bottom Bracket. In addition, the RSP 4.0 has been designed to work with either 120mm Disc, or traditional V brakes.

Put this combination of race proven geometry and design upgrades together, and you’re left with one of the best alloy BMX race frames on the market.
