Every time Chase updated the RSP frame, Chase took all the feedback from Connor, then Joris and other Pro team riders to make the RSP 5.0 the culmination of all current upgrades, the best aluminium frame to date. The frames Chase RSP 5.0 (from Expert XL) feature a conical head tube, a seat post tube that still maintains the Aero profile, closed rear dropouts, a Press Fit bottom bracket, hydroformed premium ultralight 7005 T6 aluminium tubes with triple and double butting, Muscle forming stays that are stiffer and transfer energy to pedaling, and now a new internal cable routing from the head tube through the down tube and bottom bracket, exiting at the rear stay. For Mini - Expert sizes, the cable routing exits at the bottom of the down tube and has a straight 1-1/8” head tube and a Euro bottom bracket. All Chase RSP 5.0 frame sizes are designed solely for the use of disc brakes and require a separately sold Elevn disc brake adapter that has been designed to work properly with these frames, though other brands may work. The dropouts have been revised to provide better clearance for a wide range of disc brake calipers, enhancing overall braking performance, and are now compatible with both post mount and flat mount disc brake systems. The Chase RSP 5.0 frame is now offered in an OS20 frame size option with geometry designed for riders wanting to use OS20 size wheels, forks, and tyres. The OS20 uses oversized rims, tyres, and forks to provide taller riders with a more comfortable ride.
