Triathlete in aero position looking ahead

The AeroGain experience

This isn’t just an upgrade — it’s a statement.

The AeroGain cockpit was built because we were tired of compromising. Too many setups sacrificed either comfort, control, or aero. So we created the system we always wanted — and now we ride it.

Why Choose AeroGain?

We’ve spent hours in the pain cave, the races where comfort slipped, and the long rides where the gear just didn’t work. That’s why AeroGain was built — not to look fast, but to be fast. Every product we make is tested by real triathletes, in real race conditions, before it ever reaches you.

We Built It. They Raced It. Here's What They Say.

★★★★★
The AeroGain mono arm rest completely changed my position. It gave me the stability and support I needed to hold aero for longer — and I felt the difference straight away. It’s honestly one of the best upgrades I’ve made to my setup.
