The lightest protection you’ll ever forget you’re wearing. Pull them on. Drop in. Feel nothing — until it matters.
Built to move
When you ride hard, your gear has to stay locked in. The Fly R Sleeves combine a high-cut design with anti-slip silicone grip and ergonomic shaping that follows your movement.
No shifting. No restriction. Just flow.
Softshell materials and flexible spandex adapt to every motion, while laser-cut ventilation and mesh zones keep air moving where you need it most. The knee sleeve adds an elastic strap for extra hold. Light on the climb. Unnoticeable on the descent. Ready the moment things get unpredictable.
Protection that adapts
At the core of the Fly R Sleeves is the RE ZRO® pad, a next-generation material designed to react instantly when it matters. On impact, it absorbs energy. Right after, it returns to its original form. No bulk. No stiffness. Just protection that stays invisible until you need it.
The open geometry keeps it vented and flexible across changing conditions. From cool morning laps to hot summer sessions, it performs consistently. And because RE ZRO® is a single-polymer TPE, it is fully recyclable* and biodegradable** under controlled conditions.
Protects When It Counts
Engineered to meet CE-certified EN 1621-1 Level 1 standards, the RE ZRO® pad delivers proven impact absorption in a breathable, low-profile package. Whether you’re flowing through singletrack, navigating technical sections, or pushing your limits in the park — the Fly R Sleeves are built for real riding.

Mountain biker Jonas Sonnenberg:
“The new TSG Fly R pads are super comfortable to wear. They feel more like a lightweight layer you just pull on, while still giving me the protection I need on the trails.”
BMX rider Paul Thölen
“I’m a big fan of the Fly R Knee Sleeves, mainly because of how well they fit. The material feels super comfortable, and even after a long session you forget you’re wearing them. They’re also so slim that they disappear under long pants.”
