Huffy BMX Primus Race Frame Description:
The Huffy Primus BMX Race Frame is an elite-level platform designed to deliver podium-topping speed while drastically simplifying trackside maintenance. Constructed from lightweight 6061 T-6 aluminum and featuring race-proven geometry, this frame ensures maximum stiffness and explosive acceleration out of the gate. Available in Pro, Pro XL, and Pro XXL sizes, the Primus was developed alongside Olympic racers to handle the rigors of top-tier competition. Its oversized, threaded T47 bottom bracket provides exceptional power transfer and durability, ensuring the bike remains incredibly responsive under heavy pedaling.
Beyond its raw speed, the Primus is engineered to eliminate race-day headaches. It introduces the patent-pending C.A.G.E. (Concealed Appearance Guided External) brake routing system, which offers the sleek aesthetic of internal routing while allowing riders to perform complete brake system swaps using just a 3mm hex key—no bleeding or hose routing required. Combined with an advanced integrated dropout system and tool-free, thumb-wheel chain tensioners, the Primus makes rapid wheel changes and precision adjustments effortless. Complete with included 15mm hardware (10mm and 20mm available aftermarket), this affordable high-end frame ensures racers spend less time wrenching and more time winning.
