Climbing Isn’t Just a Challenge. It’s a Statement.
Every ascent is a battle with gravity — and a conversation with your limits.
We believe true climbing performance isn’t about being fragile and light — it’s about balance.

PURA ONE 4540 was born from that belief: featherweight form, uncompromising strength, and a rhythm that flows with every climb.

Light, with Purpose
Wave-profiled at 45/40mm and built from Toray T1000+T800, this wheelset weighs just 1160g, yet responds with razor-sharp stiffness. Every watt hits the ground like thunder.

Ride Your Way
Hooked rims. 22mm internal. Fits 25C to 48C.
From racing slicks to gravel grip — it’s ready for your ride.

Strength You Can Trust
16 integrated carbon spokes. One-piece molded design.
Now reinforced with 8 titanium bolts connecting the hub flange — for strength that won’t quit, even under full-gas effort.

Light. Strong. Relentless.
This isn’t about perfection. It’s about performance that inspires.
When you ride the 4540, you don’t fight the mountain —
you rise with it.

“The mountain is there. We’ll meet you at the top.”
