An all-around, road racing helmet that is light, cool, fast, and features the added protection of Mips.

Velocis Mips is now lighter, cooler, and faster than ever thanks to insight and feedback from Trek-Segafredo. And with a full suite of pro-level features, this helmet is bound for the podium.

Velocis is designed with protection front and center.

This helmet earned a Virginia Tech 5-STAR safety rating and features a Mips Air safety system.

Unexpectedly light

A low-profile design and new lighter-weight components, like an OCLV Carbon inlay, make Velocis 6 grams lighter than before.

Cool is fast

Multiple rounds of computational fluid dynamic modeling and wind tunnel testing revealed a new helmet design that’s optimized for airflow and is 38% cooler* and 18 seconds faster at 45 km/h.

*Compared to the prior Velocis and the original Ballista

A Better Fit System

For that Goldilocks fit, Velocis features a single-lace, 360° BOA® fit system with two lace height positions and three yoke positions — offering complete customization.

Secure Storage

Velocis’ rubberized side vents make it easy to stow away your sunglasses when you’re not wearing them.

A Clear View

Velocis features a beveled edge above the brow that opens up your field of view and lets you easily see the road ahead — even when tucked in the drops.
