CHASE rsp5.0 BMX Race Frame Pro XL 21 TT Black With Holographic Decals

Season:2026

Brand:Chase

Code:CHACADR420

Chase BMX started with 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, and other Pro riders we sponsored. The RSP 5.0 is the culmination of the refinements and upgrades to make it our best Alloy frame ever.

The Chase RSP 5.0 Frames feature Tapered Headtube (Expert XL and above sizes), an Aero Seat Post tube, Enclosed Rear dropouts, Press Fit Bottom Brackets (Expert XL and Above), Triple and Double Butted tubes, Hydro and Muscle formed 7005 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, and exits out of the Chain Stay (Expert XL and Larger), and 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, and now compatible for both post and 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 with refined geometry for riders wanting to use OS20 wheels, forks, and tires. OS20 uses the oversizes rims, tires, and forks to give larger riders a more comfortable ride as well as experience all the benefits of OS20.

11 OPTIONS IN 20″ FRAME SIZES:

Mini, Junior, Expert, Expert XL, Pro, Pro+, Pro XL, Pro XL+, Pro XXL, Pro XXL+, Pro XXXL

Born from some of the best alloys for building BMX race bikes, our special 7005-T6 SpeedLite alloy is the perfect blend for our Hydroforming process, giving our 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 feature the triple butting on our line of RSP 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 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 with the RSP 5.0 frame and against the completion.

Chase RSP frames use 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 with 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 and 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 ACT and RSP Frames feature the Aero seat post tube, seat post, and seat post clamp into BMX racing. This is to not only to help gain fractions of a second on the track with 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 and Seat Stays, a technique to give the back end of the ACT and RSP frames the stiffness and design shape we wanted and needed for optional design a special mold and process were needed to let us build the ultimate frame. Used with Carbon Fiber or Alloy to do just that, while letting us design the exact shape, design, and thickness to offer the optional designed back end on the Chase frames.

For Chase ACT and RSP frames, we have designed them to be able to take the extra force created by using a disc brake and disc brake mount. The Dropouts, as well as the seat and chain stays need to be designed with a Disc brake in mind to give you the extra strength and clearance needed for disc mounts and the disc brake Caliper as well, while still be able to use the entire length of the drop out area.

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 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, with the offered 1.5” lower bearing, when the headset has an optional 1-1/8” to 1.5” fork race option.

Chase 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, with the traditional Euro BB. The BB is usually lighter and easier to install and remove as well.

Chase Frames feature an Fully enclosed, Extra long (2.3″ or 60mm) axle area slot, with reinforced stainless steel plates, 20mm drop outs with removable steel plate inserts to accommodate 20mm, 15mm or 10mm rear axle hubs. The Enclosed system also houses 2 different Chain tensioner systems, an Internal system with built-in alloy tensioner, or external Chain Tensioner system, allowing you to use the full length of the dropout.

Chase Frames feature Internal Cable Routing thru the top tube, giving you the factory look, as well as providing protection for the brake cable and graphics, since the cable does not rub against the frame.

Head Tube Angles and BB height will vary by the fork and tires used when Measuring. We have updated our angles to be exact when using a IKON Carbon Fork (For 20” or 24” frames) or ELEVN Cromo OS20 Forks (For OS20 Frames) using TIOGA Fastr tires to give you the true angels and measurements. Usage of other forks and tires will give you a + or – of Heights and Angles.

Please note:
Brake fluid on paint that is not silicone-based can act like a paint thinner and 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 infliced damage due to this.

SIZING CHART

The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Chase retailer.
