Crupi Catalina 2.0 Expert 2X Race Bike Frame
Description
The Crupi Catalina 2.0 Expert 2X Race Frame is a completely redesigned BMX race frame built for riders who demand competition-level performance without stepping up to a heavier Pro frame. Hand-built in the USA from seamless drawn 6061 T6 butted aluminum, this frame delivers a winning combination of stiffness, strength, and low weight that serious BMX racers count on. The 20.5" top tube makes it ideal for riders 5'3" and taller - especially lighter riders and girls with longer legs who need front-end length without the added heft of a Pro-class frame.
The Catalina 2.0 arrives with notable upgrades over its predecessor, including wrap-around seat stays, a slightly shorter seat tube, and a fully integrated built-in Disc Adapter - no axle-mounted adapters required. Whether you're racing UCI or USA BMX tracks, this frame's geometry is race-proven and refined to keep your position consistent no matter where your rear wheel sits. It's the largest 20" frame featuring a 22.2mm seat tube, which plays a key role in keeping overall weight to a minimum.
Key Features
- USA Hand-Built Construction: Every frame is hand-built in the USA from seamless drawn 6061 T6 butted aluminum tubing for race-ready quality and consistency.
- 20.5" Top Tube: Sized for riders 5'3" and up - ideal for longer-legged riders and lighter riders who need front-end reach without the weight of a Pro frame.
- Wrap-Around Seat Stays: New-generation seat stay design adds stiffness and strength to the rear triangle for a more responsive, planted feel on the track.
- Built-In Disc Adapter: Integrated disc brake adapter eliminates the need for axle-mounted adapters - compatible with Tektro, TRP Evo, TRP Slate, and all Shimano hydraulic disc brake kits (Note: Hope, Avid, and mechanical kits are not compatible).
- 120mm Rotor Requirement: Requires Crupi's Disc Adapter kit and a 120mm rotor for proper disc brake fit.
- Teardrop Chain Stay Tubes: Aerodynamic teardrop-shaped chain stays create a stiff, strong rear end built to handle hard sprints and rough tracks.
- Square Down Tube: Larger-diameter square down tube adds frame stiffness and overall structural integrity where it matters most.
- Parallel 3/8" (10mm) Axle Slots: Axle slots run parallel to the ground so frame geometry stays consistent regardless of rear wheel position - no guessing, no compromise.
- Thicker 3D Drop-Outs: Extra-stiff drop-outs designed for disc brake use while still accommodating standard chain tensioners for easy rear wheel installation.
- V-Brake Compatible: Brake posts are included for use with all V-Brakes, giving you flexibility in your brake setup.
- 22.2mm Seat Tube: The largest 20" frame with a 22.2mm seat tube keeps weight to a minimum - a critical advantage in BMX racing.

FAQ
What disc brake kits are compatible with this frame?
The Catalina 2.0 Expert 2X is compatible with Tektro, TRP Evo, TRP Slate, and all Shimano hydraulic disc brake kits when used with Crupi's Disc Adapter kit and a 120mm rotor. Hope, Avid, and all mechanical disc brake kits are not compatible with this frame's integrated disc adapter system.
Do I need a separate disc brake adapter for this frame?
No - the Catalina 2.0 Expert 2X features a built-in disc adapter, so axle-mounted adapters are no longer needed. However, you will still need to use Crupi's Disc Adapter kit along with a 120mm rotor for proper fit and function.
What size rider is this frame designed for?
The Catalina 2.0 Expert 2X Race Frame with its 20.5" top tube is designed for riders 5'3" and taller. It's especially well-suited for lighter riders or girls with longer legs who need front-end length but aren't ready to move up to the heavier Pro-class frame.
Can I still use V-Brakes on this frame?
Yes - all Crupi frames, including the Catalina 2.0, include brake posts for full compatibility with V-Brakes. This gives you flexibility to run your preferred brake setup.
Is this frame in stock and ready to ship?
All Crupi frames are hand-built in the USA and are often in high demand. If your preferred size or color is not in stock, contact Crupi directly to be placed on their priority list - when that frame becomes available, you'll have the first opportunity to purchase it.
What is the difference between the Expert 2X frame and a Pro frame?
The Expert 2X is the largest 20" BMX race frame in Crupi's lineup and features a lightweight 22.2mm seat tube that keeps overall weight down. It's designed as a transitional frame for lighter riders who need the extra reach of a longer top tube but aren't ready for the added weight of a Pro-class frame. The Pro frame is built for heavier, more physically developed riders who can leverage the added mass for power output.
