Bontrager Velocis Helmet – Premium Road Cycling Performance
We engineered the Bontrager Velocis helmet to deliver the ultimate balance of aerodynamic speed, ventilation, and protection for competitive road cyclists. This premium helmet features MIPS brain protection technology, an advanced retention system, and strategically positioned vents that channel airflow without sacrificing aerodynamic performance.
Every element of the Velocis design serves a purpose. The helmet's shell shape reduces drag while maintaining exceptional cooling, so you stay comfortable during long training rides and intense race efforts. Our BOA® fit system provides micro-adjustable precision, creating a secure, stable platform that moves with you through every pedal stroke and sprint.
Performance Engineering

Advanced Safety Technology
The Bontrager Velocis helmet integrates MIPS (Multi-directional Impact Protection System) technology to provide enhanced protection during angled impacts. This low-friction layer inside the helmet allows the shell to rotate slightly upon impact, reducing the rotational forces transmitted to your brain.
Our in-mold construction process fuses the polycarbonate outer shell directly to the impact-absorbing EPS foam liner, creating a stronger, lighter structure than traditional helmets. This manufacturing method eliminates weak points while maintaining structural integrity across the entire helmet. We exceed all CPSC and CE safety certifications, and every Velocis undergoes rigorous internal testing protocols that simulate real-world crash scenarios.

Aerodynamic Efficiency Meets Ventilation
We spent hundreds of hours in the wind tunnel refining the Velocis shell profile to minimize drag without compromising cooling. The helmet’s elongated tail section smooths airflow separation, while the 15 strategically positioned vents create internal air channels that pull heat away from your head.
The front intake vents align with internal channels that accelerate airflow across the top of your head before exhausting through rear ports. This design maintains cooling performance even at the aggressive head angles used during time trials and breakaway efforts. Independent testing shows the Velocis saves 3-5 watts compared to traditional round-profile road helmets at speeds above 25 mph.
BOA Fit System and Retention
The Velocis features our most advanced retention system, built around the BOA® micro-adjustment dial. A single turn of the dial provides precision tension adjustments in 1mm increments, allowing you to dial in the perfect fit before every ride.
The TX1 dial mechanism is mounted at the base of your skull for optimal stability and weight distribution. This low-profile placement keeps the adjustment system out of the way while creating a secure cradle that prevents helmet movement during hard efforts. Thin, flexible retention straps distribute pressure evenly around your head, eliminating hot spots during multi-hour rides.

Velocis Helmet Questions
MIPS (Multi-directional Impact Protection System) adds a low-friction layer between your head and the helmet's inner shell. During angled impacts—the most common type of cycling crashes—this layer allows the helmet to rotate slightly, reducing the rotational forces transmitted to your brain by up to 40% in laboratory testing.
The MIPS system in the Velocis integrates seamlessly with the helmet's retention system and padding, adding only 15 grams of weight. The layer is barely noticeable during normal wear but provides crucial protection during the exact moment you need it most.
Absolutely. We designed the Velocis specifically for multi-hour road efforts where both aerodynamics and comfort matter. The 15-vent system provides exceptional cooling during extended climbs, while the BOA retention system distributes pressure evenly to prevent hot spots and headaches.
The helmet's 275-gram weight (size Medium) makes it light enough that you won't notice it during century rides or gran fondos. The moisture-wicking antimicrobial padding prevents odor buildup and manages sweat effectively during long days in the saddle. Many endurance cyclists prefer the Velocis over pure aero helmets because it balances speed with all-day wearability.
Yes, the Bontrager Velocis helmet excels as an all-purpose road cycling helmet. The aerodynamic profile provides measurable speed benefits during races and fast group rides, while the ventilation system keeps you comfortable during easier training sessions.
Many competitive cyclists use the Velocis as their only road helmet rather than switching between dedicated training and racing models. The combination of aero efficiency, cooling, safety features, and comfort makes it versatile enough to handle everything from recovery spins to criterium races. The integrated accessory mounts also support lights and cameras for training rides that extend into dawn or dusk.
Measure your head circumference about one inch above your eyebrows using a flexible tape measure. Keep the tape level around your head and note the measurement in centimeters. Small fits 51-55 cm, Medium fits 55-59 cm, Large fits 59-63 cm, and X-Large fits 63-67 cm.
If your measurement falls on the boundary between sizes, we generally recommend sizing down, as the BOA system provides substantial adjustment range within each size category. The helmet should feel snug but not tight, with no pressure points or gaps. When properly fitted, the helmet should not move when you shake your head side to side or nod up and down.
Each Bontrager Velocis helmet includes the complete helmet assembly with pre-installed MIPS liner and padding, the integrated BOA fit system, adjustable retention straps, and a set of sizing shims for custom fit refinement. We also include care instructions and registration information for our crash replacement program.
The helmet comes with our standard one-year warranty covering manufacturing defects, plus eligibility for discounted crash replacement if the helmet is damaged protecting you during a fall. Additional replacement pads and accessories are available separately through our website and authorized dealers.
The Velocis and Ballista serve different purposes in our helmet lineup. The Ballista prioritizes maximum aerodynamic efficiency with a more aggressive tail section and fewer vents, making it ideal for time trials, triathlons, and flat criteriums where cooling is less critical.
The Velocis offers better ventilation while still providing significant aero benefits, making it more versatile for varied terrain and longer rides. Most cyclists find the Velocis more comfortable for general road racing and training, while specialists choose the Ballista when absolute aerodynamic advantage matters more than cooling. Both feature MIPS protection and the BOA fit system.
Yes, all interior padding in the Velocis attaches with hook-and-loop fasteners for easy removal and replacement. We sell replacement pad sets through our website that include all foam pieces and the sweatband liner.
Replacing pads extends your helmet's usable life between cleanings and allows you to refresh the fit if the original padding compresses over time. We recommend washing the pads monthly with mild soap and allowing them to air dry completely before reinstalling. The antimicrobial treatment in the padding remains effective for approximately two years of regular use.
