Bola PRM 45G 700C Carbon Disc Wheelset — 45mm Deep, 28–32mm Internal, Tubeless-Ready, Gravel & Road

Take confident, faster miles across mixed roads and rougher gravel in the same ride. The Bola PRM 45G wheelset blends a 45mm aerodynamic rim profile with wide internal widths so you can run modern gravel tires without sacrificing road speed. Designed for riders who switch surfaces in a single day, it delivers predictable handling, fast roll, and adaptable tire support.

Bola PRM 45G 700C Carbon Disc Wheelset - Designed for mixed-surface riding

Built from Toray T800 unidirectional matte carbon and finished with full carbon blade spokes, these wheels pair lightweight construction with lateral stiffness for responsive handling. The tubeless-ready rims accept 28–50mm tires so you can tune pressure for comfort or speed, while the 45mm depth balances aerodynamic gains with crosswind stability suitable for gravel, cyclocross, and road use.

The everyday impact is immediate: you can fit wider tires for traction and compliance on rough sections, then enjoy improved aerodynamic performance on paved stretches. Reduced rotating mass and direct power transfer from the 20/20 spoke layout result in a snappier feel under acceleration and more consistent cornering response.

Why it fits your routine

• Versatile tire support: 28–32mm internal rim width options (external ~34–38mm) and tubeless-ready construction support 28–50mm tires for everything from fast all-road setups to high-volume gravel rubber.
• Aerodynamic but manageable depth: 45mm rim profile provides aerodynamic benefit and improved stability in crosswinds compared with deeper race-specific rims.
• Lightweight performance: Measured set weights of 1250g (28/30mm) and 1290g (32mm) without tape or valves reduce rotating mass while preserving strength for mixed-terrain use.
• Stiff, efficient power transfer: 20 front and 20 rear straight-pull carbon blade spokes increase lateral stiffness and lower drag for responsive acceleration and precise handling.
• Durable hub system: Bola BL350 CNC aluminum hubs with Enduro sealed bearings and a 54T ratchet (6.7° engagement) deliver reliable engagement and long service life, plus Center Lock disc compatibility.
• Modern axle standards: Thru-axle compatible with 12x100mm front and 12x142mm rear spacing for contemporary road, gravel, and cyclocross frames.
• Tested to standards: Manufactured under ISO 4210-7 with REACH compliance to support safety and materials standards.
• Support and coverage: 24-month manufacturer warranty with crash replacement handled under Bola policy for backed ownership confidence.

When comparing value versus premium branded options, the PRM 45G offers a balance of aerodynamic depth, wide internal rims for modern gravel tires, and a hub/spoke system tuned for lateral stiffness while remaining factory-direct priced, making it an effective upgrade for riders seeking significant performance gains without high-brand premiums.
