CHASE RSP 5.0 BMX FRAME

Chase BMX began with the RSP 1.0 frame, a model that Connor Fields rode from the very start. Each version since has been improved based on feedback from top riders like Connor, Joris Daudet, and other pros we sponsor. The RSP 5.0 is the culmination of these refinements, making it our best alloy frame to date.

Key Features:

The RSP 5.0 frames are equipped with advanced features, including a tapered headtube (available in Expert XL and larger sizes), an aero seat post tube, enclosed rear dropouts, and press-fit bottom brackets (for Expert XL and up). It also boasts triple- and double-butted tubing, and hydro-formed 7005 T6 premium ultralight tubing. The new internal cable routing runs through the head tube, down tube, and bottom bracket, exiting at the chainstay for larger sizes (Expert XL and above). For Mini to Expert frames, the cable exits at the bottom of the down tube.

Brake Compatibility:

All Chase RSP 5.0 frames are designed specifically for disc brakes. The restructured dropouts enhance clearance, allowing for compatibility with both post and flat-mount disc brake systems. (Disc adapter kit sold separately.)

OS20 Frame Option:

For riders seeking a larger, more comfortable setup, the RSP 5.0 is now available in the OS20 frame size, which accommodates oversized rims, tires, and forks. This option provides refined geometry and increased comfort, ideal for larger riders who want to benefit from the OS20 system.
