Trusted by Champions

The Huffy Primus BMX Race Frame delivers elite-level BMX racing performance with a lightweight 6061 T-6 aluminum frame, advanced dropout engineering, and a tool-free chain tensioner system for fast, simple adjustments. Featuring an innovative hidden brake cable cover for easier maintenance and available in Pro, Pro XL, and Pro XXL sizes, the Primus is an affordable high-end BMX race frame trusted by champions.

Clean Brake Routing

Our patent-pending C.A.G.E. (Concealed Appearance Guided External) feature delivers the same clean look as an internally routed brake line, while making full brake swaps possible with just a 3mm hex key. Its easy access lets riders keep backup systems ready for quick replacement between motos without cutting lines, bleeding hydraulics, or rerouting hoses.

Quick Change Dropouts

The integrated dropout system was designed to simplify wheel and cog changes while maintaining precise brake caliper and wheel position. The dropout plates stay fixed in the frame during swaps, helping maintain wheel alignment and significantly reducing downtime between motos.

Hand-Tunable Chain Tensioners

The Primus chain tensioner system was built for fast, precise trackside adjustments without extra tools or loose hardware. Integrated thumb-wheel adjusters let riders quickly dial in chain tension using nothing more than their fingers.

T47 Bottom Bracket

Built for stiffness, durability, and smooth power transfer, the Primus utilizes a T47 bottom bracket that delivers reliable performance under hard riding and repeated gate starts. The oversized threaded design supports larger bearings and spindle options while keeping the system easy to service.

“The Primus has far exceeded my expectations of what I was actually going to receive and ride. The attention to detail from the cable housing to the tensioner system is just above and beyond what I was ever expecting. These bikes are not the Huffys your parents would talk about.”
