Chase Element Expert 20"

Product Overview The Chase Element Expert is a complete 20" BMX bike built on a 7005-T6 hydroformed alloy frame with race-proven geometry. It combines a carbon fork, hydraulic disc brakes, sealed-bearing hubs, and precision components designed for riders aged 10-13 (4'7.5"-5'0.6"). At 18.4 lbs, this bike delivers responsive handling and durability across park, street, and race riding without excessive weight.

Key Features

• Double and Triple-Butted 7005-T6 Frame - Hydroformed and tapered tubing reduces weight in non-critical areas while maintaining stiffness where needed; same geometry as Chase's UCI World Champion and USA BMX Championship frames
• Integrated Chain Tensioner and Disc Brake Mounts - Built-in hardware eliminates aftermarket hardware clutter and ensures precise brake alignment without adjustment slots
• Ikon Pro Carbon Fork - 20mm thru-axle with alloy steerer tube for durability and stiffness; carbon legs reduce unsprung weight
• Tektro Hydraulic Disc Brakes - Resin pads and 120mm rotor deliver consistent, modulated stopping power in wet or dry conditions; superior to rim brakes for reliability and hand fatigue reduction
• Sealed-Bearing Hubs (Front and Rear) - Chase Element hubs eliminate water and dirt ingress; rear hub features 3-pawl triple-angle engagement with 72 points of contact for smooth, responsive power transfer
• Aero-Shaped Seat Tube - Aerodynamic profile reduces drag and improves handling responsiveness without compromising strength
• 26.25" Wide Handlebars with Sweep - 10° back sweep and 2° up sweep geometry positions rider arms and shoulders for control and comfort during extended riding sessions

TECHNOLOGIES

Chase Bicycles introduces the Aero seat post tube, seat post, and seat post clamp into BMX racing with our Element bikes and our ACT 1.0 and 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..

It doesn’t matter how much you can squat, if your rear hub ins’t worth squat. But with the new Chase Element Triple Precise Rear hub clutch system, all you will have to worry about is how to where to put you trophies instead of if your hub can take all the power you can dish out. The 3 pawls clutch system gives you a direct link to power, while keeping the rear hub light and easy to maintain. With 72 points of engagement, the drag is also minimal, while being secure enough for Champions riders like Connor Fields and Joris Daudet to ride on with confidence.

Chase utilizes the CNC machining process to produce out 3D Modulus Dropout and small parts of the Edge and Element 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 complete bikes. Precision machining enhances the beauty and craftsmanship ship of all frames offered from Chase.

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.

Chase has designed and added the new Enclosed Rear dropout on the Element frame was developed to add strength to the frame for usage of the Disc Brake mount, as well as the easy of having an integrated chain tensioner system built into the frame. We use this same technology on our flagship BMX racing frame, the Chase ACT 1.0 Carbon Fiber frame.

Born from some of the best alloys for building BMX race bikes, our special 6061-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.

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 utilizes the triple butting on our line of Element bikes. 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 Element 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 Element frame and against the completion.

Chase incorperates 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.

Early Chase Element bikes, RSP 4.0 & ACT 1.0 Frames both 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.
