Our fastest helmet ever
Ballista is the fastest helmet in Trek's line-up. Its aerodynamic efficiency saves riders 10.1 watts of power and more than one bike length during a final sprint versus the Velocis in a standard one-hour test.


Unexpectedly light
The Ballista is light. At 275 grams, its minimalistic, low-profile design makes for a faster helmet that's lighter than ever before.


Cool is fast
Insight from computational fluid dynamic analysis helped optimise vent and channel design for more efficient airflow, creating a cool helmet.


Mips Air safety system
Less weight, seamless integration, improved sweat management and rotational force management technology from Mips provide better performance and a better experience on the bike.


A better fit
For that Goldilocks fit, the Ballista features a single-lace, 360deg BOA fit system with two lace height positions and three yoke positions offering complete customisation.


Secure storage
The Ballista's rubberised side vents make it easy to stow away your sunglasses when you're not wearing them.

A clear view
The Ballista features a bevelled 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.

Virginia Tech 5-STAR Rating
The Ballista has received a 5-STAR safety rating from Virginia Tech's third-party testing facility, an unbiased, industry-accepted assessment of the level of protection a helmet provides to a cyclist.
