FEATURES:
Performance Optimized Aluminum Frame: Built for performance, the Helion 24 features a triple-butted aluminium frameset with a CNC'd chainstay yoke that’s precision engineered to take big hits and accommodate an impressive 2.6” tyre if required. The Hellion 24 comes ready spec'd with a 2.25”/ The frame tubing has been deliberately crafted to balance strength (at the pressure points) with lightness, ensuring we don’t waste valuable grams where we don’t need it. Threaded thru axles ramp up frame stiffness while sliding dropouts give them handling and size adjustments as they progress.
Rapid Fire Shifters: Simple, versatile and durable, Shimano’s Deore 5100 1x11 gives progressing riders the gear ratio they need with none of the fuss. he simple 1x set-up is fully optimised for technical trail and jump lines without adding any unnecessary weight. Shimano’s HyperGlide+ shifting gives quick, precise feedback and seamless shifting even under load while the Shadow+ Rear derailleur uses clutch technology to prevent chain slap and slip on the big hits.
Long, Low & Slack: The Hellion 20 is built for performance with a geometry optimised for speed, technical acumen and confidence on the gnarly bits. The low centre of gravity keeps them balanced in the berms while the slack head tube angle takes (some of the drama) out of descending. The short seat stays give the bike a playful responsive feel (while also making manuals just a little easier to master).
Full Gas Chainset: The crankset and single ring set-up give the Hellion 20 an awesome mix of performance, safety and pedalling efficiency that you simply won’t find on other bikes this size. The narrow wide chain ring stops the chain from flapping and slipping and works in harmony with 127mm cranks for pedalling efficiency.
Anatomically Designed Cockpit: The Richey Jr cockpit is anatomically designed for progression and control. When everything fits right, steering becomes more precise, more controlled. The lock on grips prevent hand slip in the inevitable wet muddy conditions. Ritchey Logic have been at the forefront of component design for the past 50 years. We’ve collaborated with them for over a decade, producing some of best age specific components to ever grace a kids’ bike.
Big Kid Fork, Little Kid Bike: The Hellion 20 comes equipped with 80mm of smash proof front suspension courtesy of RST Spex. Featuring the same levels of adjustability typically found on much bigger kids’ bikes, the Hellion 20 can withstand pretty much anything little rippers decide to throw at it. Fine tune the float with adjustable air suspension, compression and rebound to dial in their ride according to the demands of their skill set, terrain or current weight.
Lightweight Adjustable Brakes: Featuring a lightweight, smooth modulation, plenty of adjustability and ultra reliable braking, it’s no wonder we’re such big fans of Shimano’s Deore MT500s. Braking feedback is predictable with a smooth modulation that prevents unnecessary emergency stops while the 160mm 6 bolt rotors give bold riders the confidence they need to go hard and stop harder.
SRAM GX Drivetrain: The SRAM GX 1x10 is a robust, efficient, and versatile drivetrain that balances simplicity with performance. The low-maintenance setup which saves valuable weight without sacrificing performance. With its smooth, accurate shifting, superior weight and robust build, there’s a reason why SRAM GX is the drivetrain of choice for so many pros.
MTB Wheels that Go Hard: Fully sealed bearing hubs, tubeless compatible, double wall rims and optimised spoke count means these wheels rip. Because there’s no point speccing a great bike with weak wheels. Sealed bearings keep mud, water and corrosion at bay while double wall rims give you twice the confidence on rocks and roots. The optimised spoke count means you won’t have to worry about buckled wheels while thru axles make the rare times you do need to swap tyres a breeze.
Tyres that keep you on track: Big rips require big tyres and we’re not playing around when it comes to speccing the Hellion. Whether you’re navigating mud, berms, ruts or roots, Vee’s tubeless compatible 2.25" Rubber Crown Gem tyres deliver traction, control and protection while still remaining surprisingly light.
Drop it like its hot: The Hellion 24 comes engineered with the pre-installed ports and guides to accommodate the dropper post of your choice. Internal cabling keeps wires, and fail points to a minimum leaving them to focus on better descents, improved handling and even more confidence.
