FAQs

How long do they last/how do I care for them?

Wash cold, air dry, no bleach or iron. Durable for many seasons of training and racing if cared for.

Are they best for TT, triathlon, or all cycling?

Perfect for triathlon or any non-UCI TT or solo efforts where aero is king.

Do I need to shave my legs for best effect?

For max aero gains, shaved legs are ideal—but even without, SUB22 will save watts and cut your time.

Is this product UCI legal?

No—like all aero sleeves, they exceed current UCI legwear restrictions but are great for all triathlon and non-UCI racing.

How do I pick my size?

Measure your calf at the widest point: S/M fits 30–40cm, L/XL fits 40–50cm circumference.

Can I wear these under my wetsuit and all race?

Yes! Designed to stay put—triathletes use them right through the swim, bike, and run.

What’s the main difference between SUB22 sleeves and full TT calf sleeves?

SUB22 is optimized for speeds below 22mph—better aero patterning for recreational, tri, or age-group riders.
