Bola 700C Carbon Disc Brake Wheelset | 45mm & 50mm Wavy Profile | 25mm Inner Wide | Road & Training

Bola 700C Carbon Disc Brake Wheelset — 45mm & 50mm Wave Profile

The Bola 700C Carbon Disc Brake Wheelset delivers aerodynamic efficiency and structural rigidity for road cycling, endurance training, and mixed-surface use. Available in 45mm and 50mm wave-profile rim depths with a 28mm outer width, this wheelset suits riders who want measurable performance gains without sacrificing day-to-day reliability. Weighing 1,470g ± 10g per pair, it fits within the competitive range for disc brake carbon wheelsets targeting daily training and racing use.

Rim Specifications

Choosing between 45mm and 50mm: The 45mm depth offers a more stable ride in crosswinds, making it the preferred choice for exposed routes, hilly terrain, and heavier riders. The 50mm depth provides marginally greater aerodynamic advantage at speeds above 35 km/h, suited to flat road training and criterium-style riding. Both depths share identical hub, spoke, and width specifications for consistent handling.

Hub & Bearing System

• Brand: Bola NBK Bearing Disc Brake Straight-Pull Hub
• Front Hub: 2 sealed bearings, O.L.D. 100mm
• Rear Hub: 4 sealed bearings, O.L.D. 135mm
• End Cap Compatibility — Front: M9, M12, M15
• End Cap Compatibility — Rear: M10, M12, M12×142

The straight-pull hub design reduces spoke fatigue at the elbow, contributing to a more consistent tension distribution across the wheel's service life. Four sealed rear bearings support lateral load management under sustained out-of-saddle efforts.

Spoke Configuration

• Spoke Brand: Pillar 1423
• Spoke Count: 24 front / 24 rear
• Lacing Pattern: 2× Cross (front and rear)
• Max Spoke Tension: 180 kgf
• Trueness Tolerance: ±0.2mm offset

Pillar 1423 bladed spokes are a recognized choice in performance wheelbuilding for their aerodynamic cross-section and tensile reliability. A 24-spoke 2× cross pattern balances lateral stiffness with road compliance — a common configuration for all-round endurance and training wheels.

Load & Pressure Ratings

• Min / Max Tire Pressure: 100 / 125 psi (6.9 / 8.6 bar)
• Maximum Rider Weight: 120 kg (264 lbs)

Tradeoff note: The 28mm outer width and 22mm inner width accommodate tire widths from 25mm to 32mm, enabling light gravel or mixed-surface use. However, the 100 psi minimum pressure and 125 psi maximum ceiling are calibrated for road tires; tubeless-specific pressure ranges should be confirmed with your tire manufacturer before setup.

Package Contents

• 1× Front wheel (45mm or 50mm, as selected)
• 1× Rear wheel (45mm or 50mm, as selected)
• 3× Spare spokes (Pillar 1423)

Weight: 1,470g ± 10g per pair (excluding accessories)

Frequently Asked Questions

Is a 45mm or 50mm rim depth better for everyday road cycling?

For most daily cycling and mixed-condition training, the 45mm depth is the more practical choice. It handles crosswinds more predictably and reduces rider fatigue on varied terrain. The 50mm depth is better suited to controlled flat environments where aerodynamic efficiency is the priority.

Can this 25mm inner wide carbon wheelset handle light gravel riding?

Yes. The 25mm inner width supports tire widths up to approximately 32mm, which is suitable for light gravel or paved paths. For sustained off-road or technical gravel use, a wider inner rim (25mm+) would provide better tire support and puncture resistance.

What disc brake axle standards does this wheelset support?

Front axle options include 9mm QR (M9), 12mm thru-axle (M12), and 15mm thru-axle (M15). Rear options include 10mm QR (M10), 12mm thru-axle (M12), and 12×142mm thru-axle. This covers the majority of modern road, gravel, and hybrid disc brake frames.

What is the maximum rider weight for this wheelset?

The rated maximum rider weight is 120 kg (264 lbs), inclusive of rider, clothing, and cargo.

Does this wheelset come with a warranty?

Bola offers a two-year warranty on this wheelset, covering manufacturing defects in the rim, hub, and spoke assembly under normal use conditions.
