Bola CE 45G Carbon Gravel Wheelset 700C, 45mm Deep, 34–38mm Width, DT Swiss Hub, Tubeless Ready

The Bola CE‑45G 700C Carbon Gravel Wheelset is a race‑oriented hookless gravel‑focused carbon disc wheelset built for gravel racers, all‑road enthusiasts, gran fondo mixed‑surface riders and light bikepackers. Striking a finely tuned balance between 45 mm aerodynamic rim depth, generous 30 mm hookless internal width and impact‑optimized carbon lay‑up, it delivers real‑world speed on rolling gravel, hard‑pack trails and paved asphalt in one versatile wheelset. As Bola’s competitive‑grade gravel offering, it brings pro‑level hookless rim technology at direct‑to‑consumer pricing, outperforming far more expensive name‑brand gravel wheel alternatives.

Built with premium Toray T800 unidirectional matte carbon fiber, purpose‑specific reinforced gravel lay‑up strengthens rim sidewalls and bead seat against trail impacts, rock strikes and repeated rough‑surface vibration. Complete wheelset weight hits 1270g per pair (±30g, excluding rim tape & tubeless valves). The 45‑mm mid‑deep profile delivers measurable aerodynamic gains on fast gravel sections and paved rolling roads, while remaining far less sensitive to cross‑winds compared to 50 mm+ deep gravel rims.

34 mm external / 30 mm hookless internal rim, fully tubeless‑ready out‑of‑box, ETRTO‑2023 hookless safety compliant. Optimized tire range 33‑52 mm. Run 34‑38 mm for fast gravel racing and all‑road gran fondo; fit 33‑52 mm high‑volume gravel rubber for rocky, loose and muddy terrain. The wide hookless bed enables safely lowered tubeless pressures, boosting corner traction, smoothing trail buzz and drastically cutting pinch‑flat risk. Hookless design also reduces weight and eliminates bead‑hook stress points common on traditional hooked gravel rims.

Powered by robust BL150 gravel‑spec hub with steel‑ceramic hybrid bearings and 54‑tooth ratchet engagement. 54‑tooth ratchet yields 6.7‑degree fast engagement, nearly eliminating pedal lag for instant power response during gravel surges, technical corner exits and steep out‑of‑the‑saddle climbs. Hybrid steel‑ceramic bearings balance dirt‑mud contamination resistance, smooth free‑spin and long service life for dirty off‑road conditions. Laced with heavy‑duty Foil carbon spokes, 2‑cross lacing pattern, tuned for gravel‑specific load cycles: delivering high lateral stiffness for sprint power transfer plus controlled vertical compliance to soak up constant trail vibration. Center‑lock disc mount, 12x100 mm front /12x142 mm rear thru‑axle standard.

Rigorously lab‑tested to ISO 4210‑7 cycling safety standards. Passes 750 000‑cycle gravel‑oriented fatigue testing and >45 J enhanced impact resistance for off‑road usage. Strict in‑house QC validates rim trueness, roundness, spoke tension uniformity and dynamic balance for consistent hand‑built quality for race day and season‑long adventure riding. Maximum system weight 115 kg, suitable for most rider + bike + gear load combinations. UCI‑approved construction for amateur gravel race eligibility.

Quick Buyer Insight vs other Bola gravel models: CE‑45G features hookless 30 mm internal reinforced gravel lay‑up, 45 mm aero depth. Compared to SL‑35G (35 mm hooked, steel spokes): better aerodynamics for fast gravel races. Compared to PRO‑50G (carbon foil‑spoke flagship): more conservative price, proven foil carbon spoke durability for heavy gravel abuse. Best for gravel‑racing & all‑road mixed terrain; not recommended for fully‑loaded expedition bikepacking or downhill mountain biking.
