Crupi Catalina 2.0 Mini Cruiser Race Frame


Description

The Crupi Catalina 2.0 Mini Cruiser Race Frame is a completely redesigned, competition-ready BMX frame built for young riders between 4'3" and 4'5" tall. Handcrafted in the USA from seamless drawn 6061 T6 butted tubing, it delivers the race-winning geometry Crupi is known for - now updated with wrap-around seat stays, a slightly shorter seat tube, and a built-in disc adapter that eliminates the need for axle-mounted adapters.

Every detail of this frame is engineered for speed and strength. Teardrop-shaped chain stays stiffen the rear end, square-profiled down tubes add rigidity, and parallel 3/8" axle slots ensure consistent geometry no matter where the rear wheel is positioned. Whether your young racer is lining up at a local BMX track or competing at a sanctioned UCI or USA BMX event, the Catalina 2.0 delivers a platform built to win.


Key Features

  • Hand-Built in the USA: Every frame is individually crafted at Crupi's facility - quality you can see and feel in every weld.
  • 6061 T6 Butted Tubing: Seamless drawn aluminum tubing provides an ideal strength-to-weight ratio for racing performance.
  • 17.75" Top Tube: Sized specifically for riders 4'3" to 4'5", delivering proper fit and confident handling on the track.
  • Built-In Disc Adapter: Crupi's all-new integrated disc adapter removes the need for axle-mounted adapters - compatible with Tektro, TRP Evo, TRP Slate, and all Shimano hydraulic disc brake kits (requires Crupi Disc Adapter kit and 120mm rotor).
  • Wrap-Around Seat Stays: Updated frame architecture improves rear-end stiffness and frame responsiveness.
  • Teardrop Chain Stay Tubes: Aerodynamically shaped for a very strong and stiff rear triangle, reducing flex under power.
  • Square-Profile Down Tube: Larger diameter squared tubing stiffens and strengthens the front triangle where it matters most.
  • Parallel 3/8" (10mm) Axle Slots: Horizontal dropout slots keep frame geometry consistent regardless of rear wheel position.
  • Thicker 3D Drop-Outs: Extra-stiff drop-outs designed for disc brake use while still accommodating standard chain tensioners.
  • V-Brake Compatible: Brake posts are included for use with all V-brakes, giving you flexibility in brake setup.
  • 1" Integrated Head Tube & EB24 Euro BB: Industry-standard specs for easy sourcing of compatible headsets and bottom brackets.

Why You'll Love It

Crupi has been a trusted name in BMX racing for decades, and the Catalina 2.0 represents the brand's continued commitment to building elite-level race equipment right here in the United States. Every frame is hand-built to tight tolerances, ensuring that no two frames leave the shop without meeting Crupi's exacting standards. The updated geometry, integrated disc adapter, and refined tube shaping make this the most capable Catalina frame Crupi has ever produced.

For parents and coaches investing in a young racer's development, the Catalina 2.0 is a frame that grows with a rider's ambition - tough enough to handle the demands of frequent racing and refined enough to give a competitive edge at every level. Because these frames are hand-built in the USA in limited quantities, they sell out quickly. If you're serious about putting your rider on the best Mini Cruiser frame available, this is it.

FAQ

What disc brake kits are compatible with the Catalina 2.0?

The Catalina 2.0's built-in disc adapter is compatible with Tektro, TRP Evo, TRP Slate, and all Shimano hydraulic disc brake kits. Note that Hope, Avid, and all mechanical disc brake kits do not fit. You must also use Crupi's Disc Adapter Kit along with a 120mm rotor for proper installation.

Can I still use V-brakes on the Catalina 2.0?

Yes! All Crupi Catalina 2.0 frames include brake posts for full compatibility with V-brakes. Whether you prefer the simplicity of V-brakes or want to run a hydraulic disc setup, this frame has you covered.

What size rider is the Mini Cruiser frame designed for?

The Catalina 2.0 Mini Cruiser frame is designed for riders between 4'3" and 4'5" tall. It features a 17.75" top tube, which is the standard sizing for Mini Cruiser class racing in both USA BMX and UCI competition.

What headset and bottom bracket does this frame use?

The Catalina 2.0 uses a 1" integrated head tube and a traditional EB24 Euro bottom bracket shell. These are standard BMX specs, making it easy to source compatible components. Crupi offers their own Factory Integrated Headsets designed to work perfectly with this frame.

Is this frame sold with components, or is it frame-only?

The Catalina 2.0 is sold as a frame only - no fork, headset, or other components are included. If you need a complete disc brake setup, you'll also want to pick up Crupi's Disc Adapter Kit separately.

Why are these frames sometimes out of stock?

Every Crupi frame is hand-built in the USA in small batches, which means inventory moves fast. Crupi takes priority list requests - if your preferred size or color is out of stock, contact them directly to be added to the list so you're first in line when that frame is produced.
