Over the past 4 years, we have been designing, developing, testing, and refining the next level CHASE BMX frame, made out of Carbon fiber.

SIMPLY THE BEST BMX RACE FRAME EVER CREATED

Chase BMX is about progression. When we introduced the RSP frame series, we utilized hydroformed technology to its maximum to create the ultimate Alloy BMX frame. With the RSP 3.0 and the Aero Dynamic Seat tube and post, we pushed the development even further. But we are always looking for the next best thing. Here it is!

Over the past 4 years, we have be hard at work. Designing, Developing, Testing, modifying, testing some more, and having our Champion Riders Connor Fields and Joris Daudet do real word testing on the track. This was all is a quest to raising the level of current BMX frames and making the best possible frame for CHASE BMX, the ACT 1.0 Carbon Fiber Frame. After all the work, we are excited to offer you the chance to #winwithchase on what we feel is the best BMX race frame ever created.

The Chase ACT (Advanced Carbon Technology) frame utilizes todays most advanced process to manufacture a BMX frame that can take the abuse of Pro Level, Supercross Style racing, but not be too stiff to make your ride too harsh.

The main type of carbon fiber used for the manufacture of bicycle frames and parts are normal tow (under 12000 fibers) carbon fiber, like T700, or commonly known as 3k, 12k weave, and UD (uni-direction) carbon fiber. UD has the highest tensile strength of these listed Carbon Fiber type and is at this time the ultimate type of Carbon Fiber to be used for a BMX frame. Tensile strength is the amount of force needed to cause the fibers to breakdown, while the tensile modulus is a measure of the carbon fiber’s stiffness. We exclusively use the UD Carbon when building the Chase ACT 1.0 Frame to make sure the frames is of the highest quality available. Its not only stronger than most strands of Carbon Fiber, but it is also lighter, but this all comes with a higher cost. But when we designed the ACT frames, we were worried about performance and quality first, price was an afterthought.

As well, we add new technical advancements like Aero Seat Post/Clamp system, a 1-1/8″-1.5″ tapered head tube with internal cable routing, a press Fit BB86 Bottom Bracket, and new enclosed plated dropouts with integrated chain tensioner system, the ACT 1.0 has been designed to work with 120mm Disc brakes or traditional V brakes, with the optional ELEVN Disc Brake adaptor and 120mm Disc.

They say you get what you pay for, but with the Chase ACT 1.0, we stills you are getting a great value, as who can put a price on Victory? #winwithchase

TECHNOLOGIES

Chase ACT Frames feature UD Carbon Fiber, one of the highest tensile strength fibers and is the ultimate type of Carbon to be used for a BMX frame. Tensile strength is the amount of force needed to cause the fibers to breakdown, while the tensile modulus is a measure of the carbon fiber’s stiffness. We exclusively use the UD Carbon when building the ACT Frames to make sure it is of the highest quality. Its not only stronger than most strands of Carbon Fiber, but is also lighter.

Chase ACT 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 & 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 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.

Chase ACT 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 ACT 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 ACT 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 ACT 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.

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.
