Chase BMX started with the RSP 1.0 frame, with which Connor Fields won races from day one. Each time Chase updated the RSP frame, they incorporated feedback from Connor, then Joris, and the other Pro riders on the team, making the RSP 5.0 the culmination of all the upgrades at the time—the best aluminum frame to date.
Chase RSP 5.0 frames (from Expert XL upwards) feature a tapered head tube, a seat tube with the same Aero profile, closed rear dropouts, a Press Fit bottom bracket, hydroformed 7005 T6 Premium ultralight aluminum tubing with triple and double butt, Muscle forming seat stays that are stiffer and more efficient at returning power to the pedals, and now a new internal cable routing The cable runs from the head tube, through the down tube and bottom bracket, and out onto the seat stay. For Mini - Expert sizes, the cable routing exits at the bottom of the down tube and they feature a straight 1-1/8" head tube and a Euro bottom bracket.
All Chase RSP 5.0 frame sizes are designed for disc brake use only and require an Elevn disc brake adapter, sold separately.Which was designed to work correctly with these frames, but other brands may work. The dropouts have been redesigned to offer better clearance for a wider range of disc brake calipers, improving overall braking performance, and now compatible with post mount and flat mount disc brake systems.
The Chase RSP 5.0 frame is now offered as an option for OS20 frame size with a geometry designed for riders wishing to use OS20 size wheels, forks and tires. The OS20 uses oversized rims, tires and forks to offer taller riders a more comfortable ride.

Note:The weights of the RSP 5.0 frames indicated are weighed exactly, including paint, stickers and varnish.
Note 2:
Brake fluid on paint that is not silicone-based can act as a paint thinner and eat away at your paint coating, causing it to peel.
Due to the different types of paints/decals/materials used for BMX parts, do not allow brake fluid to touch any part of the bike, as this can lead to significant self-inflicted damage.
