Bola PRM 50G Carbon Disc Wheelset 700C – 50mm Deep, 28–32mm Internal, Tubeless-Ready, Blade Carbon Spokes

Take sustained road miles, rough gravel stretches, or cyclocross circuits with a wheelset built to feel fast and confidence-inspiring across mixed terrain. The Bola PRM 50G pairs a 50mm aerodynamic rim with wide internal profiles so you can run modern tubeless tires at pressures that balance speed, grip, and comfort. Riders upgrading from stock wheels will notice quicker acceleration, improved climbing feel, and stable handling at speed.

Bola PRM 50G - Designed for versatile road, gravel, and cyclocross use

The PRM 50G was engineered to deliver aerodynamic gains without sacrificing tire support or everyday usability. Toray T800 unidirectional matte carbon construction and straight-pull blade carbon spokes create a wheelset that is lightweight, stiff, and durable enough for training, racing, and adventure rides. Tubeless-ready rims and a range of internal widths make it easy to fit anything from narrow endurance road rubber to wide gravel tires.

Beyond raw performance metrics, these wheels change the way a bike feels: reduced rotational mass enhances responsiveness when you accelerate or climb, while the wider rim shapes stabilize wider tires for predictable handling on loose or uneven surfaces.

Why it fits your routine

• Aero and depth: 50mm rim depth gives measurable aerodynamic benefit on sustained efforts and higher-speed road sections.
• Modern tire compatibility: Available in 28mm, 30mm, or 32mm internal widths (34–38mm external) to support 28–50mm tubeless tires for mixed-surface flexibility.
• Lightweight construction: Wheelset weight of 1250g (28/30mm) or 1290g (32mm) reduces rotational mass for sharper acceleration and climbing performance.
• Stiff, efficient build: Blade carbon spokes in a 2-cross pattern (20F/20R) and a Toray T800 carbon rim deliver direct power transfer and responsive handling.
• High-engagement hub: CNC alloy BL350 hub with Enduro bearings and a 54T ratchet system provides quick engagement (6.7°) for immediate power response.
• Disc and axle compatibility: Center Lock rotor interface and thru-axle compatibility (12x100 front / 12x142 rear), with QR adapters available for broader fitment.
• Tubeless-ready and durable: Designed for tubeless setups with reliable bead lock for modern gravel and road tires while meeting ISO 4210-7 testing and REACH compliance.
• Warranty and support: 24-month manufacturer warranty with crash replacement gives riders peace of mind for long-term use and adventure builds.
• Versatile use cases: Ideal for upgrading endurance and training road bikes, building gravel rigs that need wide tire support, cyclocross race wheels, OEM/ODM solutions for shops, and lightweight setups for bikepacking where strength and low mass matter.

Measured against comparable 50mm options, the PRM 50G offers wider internal widths and lighter claimed weights than many performance models, plus a higher engagement hub for snappier response, making it a strong option for riders seeking a single wheelset to cover road, gravel, and cyclocross demands.
