CHASE RSP 3.0 FRAME
FOR THE RSP 3.0, WE TOOK THE ALREADY WINNING FRAME AND MADE IT EVEN BETTER, EXCEEDED EVEN OUR OWN HIGH STANDARD
We took a long look at the RSP 2.0 frames and tried to think how we could improve on it. For the RSP 3.0, we took the already winning frame and made it even better, exceeded even our own high standard! The RSP 3.0 is refining the look of BMX racing and is offering riders true technical advantages.
After a long process, we decide to make on of the biggest changes we have done so far on any RSP frame, adding on the Aero System Seat Tube, in addition, we improved the look with a refined top tube, a new sleeker, lighter butted Hydroformed top tube graces each of the RSP 3.0 frames, helping reduce weight and refine the shape of the 3.0 and a updated Chain Stays on the Mini, Junior, and Expert Frames.
With BMX races being won by a fraction of a second, we looked on how we could help give the rider one more advantage with the new frames. Our championship winning geometry and proprietary Hydroformed tubes have helped racers all over the world, so this would be a tough task. So when it came time to make it better, we looked at every tube on the frame to see where we could make a improvement, while keeping the integrity of the frame the same, and making sure any change would be 100% functional. We found such an advantage. Looking to gain a slight aerodynamic advantage, we zoned in on the aero design of many Road bike and Time Trial frames. So after carful research, we have fitted the new RSP 3.0 with what we feel is a functional advantage, an aero shaped seat tube. The aero design is a first for BMX racing frames on the seat tube and post, be we have seen the data to confirm this is a true advantage. This along with our already aero head tube can offer a small advantage that could be the difference in a victory.

Chase Bicycles introduces the Aero seat post tube, seat post, and seat post clamp into BMX racing with our RSP 3.0 frames. 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.
Chase Bicycles utilizes the CNC machining process to produce out 3D Modulus Dropout and small parts of RSP frames. Using the CNC process allows us to design parts that are specifically built to work the best with our proprietary frame tubes, giving us another way to control the overall weight and strength – flex factor on the frames, to give you, the best ride and feel from our frames. Precision machining enhances the beauty and craftsmanship ship of all frames offered from Chase.
Chase Bicycles utilizes 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 frame and against the completion.
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.
Born from some of the best alloys for building BMX race bikes, our special 7005-T6 SpeedLite alloy is the perfect blend for our Hydro-forming process, giving the Element frames the core strength needed to produce unmatched speed on the track, while keeping the overall weight of the frame down to a minimum.
While each rider is unique, Chase Bicycles 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 Bicycles 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 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.
BSA or more commonly know as a “Euro” Bottom Bracket refers to the tread in type of BB, using either a Internal or External Bottom Bracket with a 68 or 73mm BB shell with 1.370/1.375″ x 24 TPI threads and a left hand thread on the drive side cup. This is now considered to be a standard threaded bottom bracket shell or bottom bracket. We use the BSA Threaded BB on both the earlier RSP frames, where a PF or Press Fit BB, with no treads is used on our ACT Carbon Frame.
Chase Bicycles incorporates the Integrated headset system on all of our frames. Simply put, It is a bicycle frame, fork and bearing system designed to eliminate the need for a headset cup. To integrate means to combine and hopefully to simplify. What has been integrated by the integrated headset? The bearings now rest inside the frame instead of inside pressed-in cups, making it easier for headset installation, helping create less maintenance on your race bike, all while making the front end stiffer and the overall bike lighter.

The Chase race frames were all designed to be strong enough for BMX Pro level racing but also as light as possible. Usage of a Disc brake and disc brake adaptor was not in the original design of these frames, therefor, it is not recommended to use such a brake on the frame, due to the stress these type of brakes put on the frame and dropouts.
Any use of a disc brake adaptor on all sizes voids the warranty of the Chase RSP 3.0 frames, as this was not the intended purpose and only a V type brake is.
