Description
ABUS GameChanger TT 1.1 – time trial and triathlon helmet
The ABUS GameChanger TT 1.1 is built for riders who measure the day in seconds. It’s ABUS’s latest time trial helmet, developed with the Movistar Team, and it suits triathletes, time trialists and track riders alike.
So where does the speed come from? A soft, flexible EVA tail at the back stops turbulence forming between your neck and the helmet. Also, the shape is designed to hold its aero advantage when you drop or turn your head, so you don’t lose much when you look around mid-effort.

How does the ABUS GameChanger TT 1.1 fit?
The Zoom Spin dial at the back sets the fit, and the half ring is height adjustable. Medium suits heads of 54–58 cm and weighs about 375 g. Then the stitched straps sit flat, so nothing flutters at race pace.
Who is it for?
First, triathletes chasing a faster bike split. Plus time trial and track riders who want a proven race helmet without the WorldTour price tag. For everyday road riding, the ABUS GameChanger 2.0 is the vented aero option.
What’s in the box
The helmet, the magnetic visor and a custom carry case, so it travels safely to the start line.
