Chase BMX started w/ the RSP 1.0 frame that Connor Fields rode from Day 1. Each time we updated the frame, we took the feedback from Connor, then Joris, & other Pro riders we sponsored. The RSP 5.0 is the culmination of the refinements & upgrades to make it our best Alloy frame ever.

The Chase RSP 5.0 Frames feature Tapered Headtube (Expert XL and Larger sizes), an Aero Seat Post tube, Enclosed Rear dropouts, Press Fit Bottom Brackets (Expert XL & Above), Triple & Double Butted tubes, Hydro & Muscle formed 7075 T6 Premium Ultralight tubing. RSP 5.0 Frames now feature a new, internal cable routing from the Head Tube, through the Down Tube & Bottom Bracket, & exits out of the Chain Stay (Expert XL & Larger), & for the Mini – Expert, the cable exits out of the bottom of the down tube.

All Chase RSP 5.0 frames are Disc Brake only designed frames. The dropouts were restructured to offer better clearance for a wide array of disc brake calibers, improving the overall braking performance, & now compatible for both post & flat mount disc brake system. (Disc Adapter kit sold separately)

The Chase RSP 5.0 Frame is now offered in a OS20 frame size option w/ refined geometry for riders wanting to use OS20 wheels, forks, & tires. OS20 uses the oversized rims, tires, & forks to give larger riders a more comfortable ride as well as experience all the benefits of OS20.


  • Aluminum 7075 T6 frame (Premium Ultralight).
  • Double butted hydroformed ​​​​​top tube.
  • hydroformed triple butted Down tube.
  • Muscle forming rear stays
  • New CNC machined dropouts
  • Internal Brake Housing routing - All new for all frame sizes - 
  • Integrated Headtube 1-1/8" (Mini, Junior and Expert Only)
  • Integrated Tapered Headtube 1-1/8" - 1.5" (Expert XL and Above sizes)
  • Euro BSA 68 (Mini, Junior and Expert Only)
  • Press Fit BB 86 (Expert XL and Above sizes))
  • 3/8" (10mm) closed dropouts with integrated tensioners

The RSP 5.0 Rear Dropouts use a standard 3/8 (10MM) bolt in axle. This is not a smaller sized thru axle, but the standard BMX Rear hub size 3/8 but the bolts need to remove from the hub, so you can insert them into the closed dropouts and then tread into the hubs. .
RSP 5.0 Frames are made exclusively for Disc Brakes & Require an adapter to do so. Both (Post & Flat mount) Elevn Disc Brake adapter was designed to work correctly with the frames, but other brands may work.
OS20 Frames require a OS20 fork for correct frame geometry & front tire clearance

20" : Mini, Junior, Expert, Expert XL, Pro, Pro+, Pro XL, Pro XL+, Pro XXL, Pro XXL+, Pro XXXL, OS Pro XXL, OS Pro XXXL
24" : Cruiser Pro, Cruiser Pro+

Included w/ RSP 5.0 Frame:

  • Chain Tensioner & Bolts.
  • Housing Damper Foam


Please note: Brake fluid on paint that is not silicone-based can act like a paint thinner & eat away at the coating of your paint, causing it to peel. Due to different types of paints/decals/materials used for BMX parts, do not let the Brake Fluid touch any part of the bike, as there can be significant self inflicted damage due to this.

Integrated Head Tube
Integrated Tapered Head Tube; for a stiffer tapered steer tube fork.
Cable routing
NEW Integrated Cable Routing,; routed from head tube to chain stays.
Enclosed Dropout
NEW Restructured Enclosed Dropouts: to offer better clearance for a wide array of disc braking w/ internal built-in tensioners.
Aero System shape to improved aerodynamics & a slightly stiffer feel.
Press Fit BB86
Press Fit Integrated BB86 Bottom Bracket: simple & easy to install.
Born from some of the best alloys for building BMX race bikes, our special 7005-T6 Speed Lite alloy is the perfect blend for our Hydroforming process, giving the RSP frames the core strength needed to produce unmatched speed on the track, while keeping the overall weight of the frame down to a minimum.
Chase utilizes the triple butting on our line of RSP 5.0 frames. A triple-butted tube means it has three different wall thicknesses along its length. Chase uses this technology to reduce the amount of material used when building the RSP 5.0 frame, decreasing its weight by 15% compared to last years frame tubes used to construct the frame. Lighter where it can be and stiffer where it needs to be means no excess weight on the bike that gives you an advantage w/ the RSP 5.0 frame & against the competition.
Chase utilizes tapered tubing to offer you the most durable, yet light weight products, to help you achieve optimum results on the BMX race track. Our tapered items, use multiple thicknesses in the same tube, so the tube can be reinforced where needed w/ precision to help reduce stress areas where needed and lighten up the areas that don’t require extra materials. In aluminum the result are tube walls that eliminate stress points, boosting strength, reducing weight and improving fatigue life. The advantage is clear : Tapered tubes enhances strength & durability, at less weight.
Hydroformed tubes have two main advantages. First, the narrow axis is a flatter surface, which means more surface area to carry the load, so it is stiffer & stronger across the minor axis. Secondly, the deeper axis is stiffer since the stiffness varies to the cube of the diameter, stronger to the square. When using an oval shaped tube on a typical BMX frame it helps reduce flex but only in one direction, but on the Chase frames, the tubes are oval in both directions in the main flex areas and these tubes help reduce flex in both main directions.
Chase RSP 5.0 Frames feature the Aero seat post tube, seat post, & seat post clamp into BMX racing. This is to not only to help gain fractions of a second on the track w/ improved aerodynamics, but the Aero tubes also offers a slightly stiffer feel. We know BMX bikes don’t need to go fully aero testing into a wind tunnel, but when races are won or lost by fractions of a second, every advantage will help.
All Chase Frames feature Muscle Forming for Chain & Seat Stays, a technique to give the back end of the ACT & RSP frames the stiffness & design shape we wanted & needed for optional design a special mold & process were needed to let us build the ultimate frame. Used w/ Carbon Fiber or Alloy to do just that, while letting us design the exact shape, design, & thickness to offer the optional designed back end on the Chase frames.
For the Chase RSP 5.0 frames, we have restructured the dropouts to offer better clearance for a wide array of disc brake calibers, improving the overall braking performance. Like the RSP 4.0, we have designed them to be able to take the extra force created by using a disc brake & disc brake mount, now compatible for both post mount & flat mount disc brake system.
While each rider is unique, Chase has developed Bio Fit sizing for our frames to offer riders the ultimate size options for BMX racing. The sizing used for the Chase line has been carefully designed to give riders the optimum power output in the size range offered. Our commitment to details and offering many size options, gives you a custom fit BMX frame, that you can buy right at your local Chase BMX Dealer..
Chase RSP 5.0 Frames use a Integrated Tapered Headtube. Tapered head tubes offer a combination for the bearing sizes. Our tapered head tubes have a 1-1/8” upper diameter to 1.5” lower diameter. this allows you to run a tapered steer tube fork, or use a full 1-1/8” fork steer tube, w/ the offered 1.5” lower bearing, when the headset has an optional 1-1/8” to 1.5” fork race option.
Chase RSP 5.0 Frames use a Press Fit style Bottom Bracket tube. Press Fit BB are a simple and easy way to install a Bottom Bracket, where the Bottom Bracket you supply for your frame has the Bearings in cups and simply press into the frame, eliminating the chance of damaging BB threads, w/ the traditional Euro BB. The BB is usually lighter & easier to install & remove as well.
Chase RSP 5.0 Frames feature an Fully enclosed, Extra long (2.3″ or 60mm) axle area slot, 10mm drop outs. The Enclosed system also houses an Internal system w/ built-in alloy tensioner, allowing you to use the full length of the dropout.
Chase RSP 5.0 Frames feature new Internal Cable Routing from the Head Tube, through the Down Tube & Bottom Bracket, and exits out of the Chain Stay (exits out of the bottom of the down tube for small sizes), giving you the factory look, as well as providing protection for the brake cable & graphics, since the cable does not rub against the frame.
