Bola PRM 40G Carbon Gravel Disc Wheelset 700C – 40mm Depth, 36mm Wide, 1230g, Tubeless

Picture yourself climbing out of the saddle on a mixed-surface stage or rolling steady on rough tarmac with confidence. The Bola PRM 40G wheelset is built to deliver lightweight responsiveness and tire stability so you keep momentum when routes change from pavement to packed gravel.

Bola PRM 40G Carbon Gravel Disc Wheelset - Designed for gravel and mixed-terrain riding

These 700C wheels combine a 40mm rim depth and a 36mm external width (30mm internal) to support high-volume gravel tires while preserving aerodynamic benefits on open road sections. At 1,230g per set (excluding tubeless tape and valves) the PRM 40G reduces rotating mass for quicker acceleration and less fatigue on long rides, while Toray T800 matte carbon construction provides a balance of strength and compliance appropriate for endurance and racing use.

The wheelset’s tubeless-ready profile accommodates 38–50c tires, allowing lower pressures for improved grip and comfort across rutted tracks or rough-surface transfers. Straight-pull blade carbon spokes and CNC-machined alloy hubs with sealed bearings create a responsive package that prioritizes power transfer, lateral stiffness, and reliable engagement for modern thru-axle disc brake frames.

Why it fits your routine

• Optimized rim geometry: 40mm depth with 36mm external and 30mm internal width supports high-volume gravel tires and stable sidewall support for rough terrain.
• Lightweight performance: 1,230g per set reduces rotational mass to improve climbing and acceleration compared with many alloy alternatives.
• Toray T800 carbon: Material chosen for a balance of stiffness, durability, and ride compliance appropriate for mixed-surface use.
• Straight-pull blade carbon spokes: Lower spoke weight and increased lateral stiffness enhance power transfer and on-trail durability under impact.
• Tubeless-ready design: Supports tubeless setups and tires up to 50c to lower rolling resistance and increase puncture protection.
• CNC-machined hubs with sealed bearings: Durable hub bodies and sealed bearings provide consistent engagement and low maintenance for regular training and events.
• Thru-axle and disc brake compatible: Built for contemporary gravel and all-road frames using thru-axles and mechanical or hydraulic disc brakes.
• Standards and warranty: ISO 4210-7 certification for safety/performance testing and a 24-month manufacturer warranty that includes crash replacement coverage.
• Tire compatibility: Engineered to work optimally with 38–50c tires, giving a wide range of setup options from fast all-road to aggressive gravel traction.

Whether upgrading from OEM alloy wheels or specifying a lightweight, cost-effective carbon option for retail or fleet use, the Bola PRM 40G offers a practical blend of aerodynamic profile, wide rim support, and durability for riders who demand versatility across varied terrain.
