Crupi Catalina 2.0 Junior Race Bike Frame


Description

The Crupi Catalina 2.0 Junior Race Frame is a fully redesigned, competition-ready BMX frame built for young riders who mean business on the track. Handcrafted in the USA from seamless drawn 6061 T6 butted aluminum, this frame delivers the race-proven geometry Crupi is known for, now refined with wrap-around seat stays, a slightly shorter seat tube, and an all-new built-in Disc Adapter - no axle-mounted adapters required. Designed for riders between 4'5" and 4'7", the 18.5" top tube puts junior racers in an aggressive, efficient position from gate to finish line.

Every detail of the Catalina 2.0 has been engineered for stiffness, strength, and race-day consistency. Tear-drop shaped chain stays, squared-off tubing ends for maximum weld surface, and parallel axle slots ensure the frame geometry stays locked in no matter where you set the rear wheel. Whether your young racer is stepping up to their first competitive season or chasing podiums at the national level, this frame is built to keep up.


Key Features

  • USA Handcrafted: Every Catalina 2.0 frame is hand built in the USA - quality controlled from weld to finish.
  • 6061 T6 Butted Aluminum Tubing: Seamless drawn construction for a strong, lightweight race frame that handles the demands of competitive BMX.
  • 18.5" Top Tube: Designed specifically for junior riders between 4'5" and 4'7", delivering proper fit and race geometry.
  • Built-in Disc Adapter: Fully integrated disc brake mounting - no axle adapters needed. Compatible with Tektro, TRP Evo, TRP Slate, and all Shimano hydraulic disc brake kits.
  • V-Brake Compatible: Brake posts included for riders running traditional V-brakes - no compromise on brake setup options.
  • Tear-Drop Chain Stays: Shaped for maximum stiffness and power transfer at the rear end of the frame.
  • Squared Tubing Ends: Increased welding surface area for stronger, more reliable joints throughout the frame.
  • Larger Diameter Square Down Tube: Adds rigidity and overall frame stiffness for more confident cornering and sprinting.
  • Parallel 3/8" (10mm) Axle Slots: Ground-parallel slots keep frame geometry consistent regardless of rear wheel position.
  • Thicker 3D Drop-Outs: Extra stiffness for disc brake use while still accommodating standard chain tensioners for easy rear wheel installation.
  • 1" Integrated Head Tube & EB24 Euro BB: Classic, proven standards that make parts sourcing and compatibility straightforward.

Why You'll Love It

Crupi has been building race-winning BMX frames in the USA for decades, and the Catalina 2.0 represents the best version of their junior race platform yet.

The integrated disc adapter future-proofs the build, letting your rider upgrade to hydraulic disc brakes as they progress without needing a new frame. With consistent geometry, proven materials, and a design that's won races at every level of competition, the Catalina 2.0 is the frame serious junior BMX racers have been waiting for. And because every frame is made to order in the USA, you know exactly what you're getting - a purpose-built race machine crafted with American pride.

FAQ

What disc brake kits are compatible with the Catalina 2.0 frame?

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 use Crupi's Disc Adapter kit along with a 120mm rotor for proper installation.

Do I need to buy the Disc Adapter separately?

The Catalina 2.0 frame features a built-in disc adapter mount, but you will still need to purchase Crupi's Disc Adapter Kit (sold separately) along with a 120mm rotor to complete the disc brake setup. The frame eliminates the need for axle-mounted adapters, but the kit itself is a required component for disc brake use.

Can I still use V-brakes on this frame?

Yes - all Crupi Catalina 2.0 frames include brake posts, so they are fully compatible with traditional V-brakes. You are not required to run disc brakes, giving you flexibility to set up the bike the way that works best for your rider.

What size rider is the Catalina 2.0 designed for?

The Catalina 2.0 Junior Race Frame with its 18.5" top tube is designed for riders between 4'5" and 4'7" in height. It is a junior-specific frame built to put smaller riders in an optimal, race-ready position.

How long does it take to receive a Crupi frame if it's out of stock?

Because all Crupi frames are hand built in the USA and made to order, they can sell out quickly. Crupi continuously produces new frame orders, and if your preferred size or color is not in stock, you can contact them to be added to their priority list. When the frame becomes available, priority list customers get first access.

Does the frame come fully assembled or as a bare frame only?

The Catalina 2.0 is sold as a bare frame only - it does not include a fork, headset, bottom bracket, or other components. You will need to source compatible parts separately to complete your build. Crupi also sells compatible headsets, posts, and their Disc Adapter Kit to help complete the setup.
