Chase Act 1.2 Carbon Frame Black/Sand

Chase ACT 1.2 Carbon Frame Black/Sand

Product Overview

The Chase ACT 1.2 is a professional-grade carbon racing frame engineered with unidirectional (UD) carbon fiber technology, proven through UCI World Cup Championships and USA BMX Elite Pro competition victories. Featuring tapered headtube geometry, internal brake cable routing, aero seat post integration, and refined chain clearance, it delivers responsive handling and premium performance for elite-level racing.

Key Features

• Uni-Directional (UD) Carbon Fiber Construction — Highest-grade carbon fiber with superior tensile strength and stiffness; lighter and stronger than standard carbon alternatives while providing optimal power transfer and responsive feel
• Carbon Monocoque Structure — Single-piece construction eliminates frame joints and weak points, maximizing structural integrity and delivering consistent performance under high-stress racing conditions
• Tapered Integrated Headtube — 1-1/8" to 1.5" tapered geometry with reinforced alloy cup accepts both standard and tapered fork steerer tubes, increasing headtube stiffness while maintaining compatibility flexibility
• Internal Brake Cable Routing — Integrated cable path through top tube provides factory aesthetics, protects brake lines from impact and cable rub, and preserves graphics integrity
• Aero Seat Post Technology — Integrated quick-release seat clamp with aero seat post tube reduces aerodynamic drag and provides fractional speed advantages critical in competitive racing
• Press Fit BB86 Bottom Bracket — Simplifies installation and removal while eliminating thread damage risk; lighter than traditional euro BB systems with improved serviceability
• Refined Chain Clearance — Optimized geometry accommodates larger gear ratios and diverse disc brake calipers for enhanced drivetrain flexibility
• 20mm Reinforced Enclosed Dropouts — Stainless steel construction with integrated alloy chain tensioner; includes 10mm (3/8") axle adapter for drivetrain versatility
• Dual Chain Tensioner System — Internal and external tensioner options maximize rear dropout length utilization for precise wheel alignment
• Professional Race Pedigree — Winning UCI World Cup Championships and more USA BMX Elite Pro races than any competing frame over the past two years
• Refined Aesthetics — Matte finish with gloss graphics for premium visual presentation

• 20mm and 10mm (3/8") dropout frame plates (installed and included)
• 20mm and 10mm chain tensioner block sets (15mm blocks sold separately)
• Internal and external chain tensioner bolts

Compatibility and Ideal Use Cases

Compatible with press-fit BB86 bottom brackets and tapered or standard 1-1/8" fork steerer tubes. Works with optional Elevn disc brake adapter for post-mount and flat-mount systems. Ideal for elite-level BMX racers, UCI World Cup competitors, and professional athletes seeking proven, competition-winning geometry and materials. The refined chain clearance and dual tensioner system provide versatility for varied drivetrain setups. Recommended for riders prioritizing responsive handling, aerodynamic efficiency, and premium carbon fiber performance.

Note: Brake fluid (non-silicone-based) can damage paint coating. Avoid contact with frame surfaces to prevent peeling or degradation.

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.

GEOMETRIES:

The Chase ACT 1.0 & RSP 4.0 Frames utilizes 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.

The Chase ACT 1.0 & RSP 4.0 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.

The Chase ACT 1.0 & RSP 4.0 Frames both use a Integrated 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.

The Chase ACT 1.0 and RSP 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.
