Trek Ballista Helmet

The Trek Ballista is Trek's fastest road helmet, built for riders where every watt counts: racers, time triallists and anyone who wants free speed on fast group rides. When the bunch is strung out, this is the helmet that cuts through the wind.

The aero-led shape was developed to save measurable seconds over a standard vented helmet, yet deep internal channels still pull air across your head to keep you cool on hard efforts. A BOA dial at the rear adjusts the fit with one hand, and full MIPS protection sits between your head and the shell to reduce rotational forces in a crash.

Key features

• Trek's most aerodynamically advanced road helmet
• MIPS rotational impact protection
• BOA dial fit system for one-handed adjustment
• Internal cooling channels for airflow at speed
• Fidlock magnetic buckle for easy on and off

Available in Small, Medium and Large. Pop in store to check fit; aero helmets sit differently to standard road lids.
