LAMINAR GR52 SL (DISC BRAKE) GRAVEL WHEELSET
Laminar GR52 SL Gravel. Uncompromised.
The Laminar GR52 is built for one thing: speed over any surface. With a 52mm deep carbon rim
and an ultra-wide internal profile, it’s made for modern gravel racing where aerodynamics, tyre
volume, and real-world durability all matter.
From endless flint roads to brutal Euro gravel, GR52 gives you the aero gains of a road wheel with
the toughness and clearance to handle the worst terrain. And at just 1185g it’s lighter than most
“all-road” wheels in its class.
Key Features:
• 52mm deep carbon rims
Designed for fast gravel deep enough to hold speed, shaped for crosswind stability, and stiff
enough to stay composed when things get rough.
• Ultra-wide internal rim profile
Engineered for 28–50mm tyres, this rim lets you run lower pressures without compromising
sidewall support improving comfort, grip, and rolling resistance on loose terrain.
• Tubeless-ready clincher
Simple, fast, and easy to maintain. Pair with a TPU tube and premium tyre for a lightweight, clean
setup that’s race-day reliable.
• Alpina Hyperlight spokes
The same ultra-responsive spoke system used in our road wheels delivering low weight, high
stiffness, and clean power transfer.
• Laminar gravel-tuned hubs
With precision bearings and DT Swiss-style internals, these hubs are made for endless miles
whether it’s mud, dust, or white roads.
Why You’ll Love Them:

• Faster over rough terrain big tyre volume + low pressure = free speed
• Stable at speed 52mm depth gives the feel of a road wheel with off-road confidence
