Bola PRM 50R 700C Carbon Disc Wheelset — 50mm Tubeless, Blade Carbon Spokes, 1230g

Take a performance-focused wheelset on long endurance rides, fast training sessions, or mixed-surface gravel days where low weight and aerodynamic stability matter. The Bola PRM 50R combines a 50mm mid-depth rim, tubeless-ready design, and blade carbon spokes to deliver quick acceleration, confident handling in crosswinds, and versatility across road and gravel setups. Riders experience a light, reactive feel without sacrificing structural certifications and practical fitment options.

Bola PRM 50R 700C Carbon Disc Wheelset - Designed for road and gravel performance

Comfort and confidence come from a wheel engineered to balance aerodynamics and tire compatibility. With Toray carbon rims, ISO certification, and tubeless-ready bead seats, the PRM 50R supports wider modern tires for improved compliance and lower rolling resistance while keeping rotational mass minimal for surges and climbs.

Why it fits your routine

• Race and training advantage: A total set weight of 1230g (without tape or valves) reduces rotational mass for faster accelerations and improved climbing efficiency compared with heavier 50mm options.
• Versatile tire support: Dual internal widths—21mm for road tires and 24mm for gravel/CX—let you run 28–32mm road rubber or 32–48mm gravel tires depending on the ride and conditions.
• Aero stability: The 50mm mid-profile rim depth is tuned to balance aerodynamic gains with better crosswind control for high-speed efforts and group riding.
• Responsive wheel build: 20 spokes front and rear, straight-pull blade carbon spokes with 2-cross lacing, enhance lateral stiffness and deliver direct power transfer for sprinting and sprint-to-cruise transitions.
• Disc-brake optimized: Disc-only configuration removes rim brake constraints, provides consistent stopping power, and supports modern disc-equipped frames and calipers.
• Tubeless-ready design: Clincher rims prepared for tubeless setups increase puncture resistance and lower rolling resistance when paired with appropriate sealant and tires.
• Durability and compliance: Manufactured from Toray carbon with in-house engineered hubs and certified to ISO 4210-7 standards, offering reliable structural performance under typical road and gravel loads.
• Practical ownership: REACH compliance and a 24-month global warranty with a crash replacement policy provide consumer protections that matter to frequent riders and shops building OEM or custom bikes.

Performance comparisons highlight the PRM 50R’s combination of a lightweight 1230g set and carbon blade spokes versus heavier mid-high models that use steel spokes, and its internal width options give it broader tire compatibility for mixed-surface riding. The wheelset is factory-direct positioned to offer competitive value while meeting certification and safety standards for everyday and competitive use.
