The Bola 700c Tubular Carbon Rim is engineered for high-performance racing and endurance cycling, offering a 45mm U-shape aerodynamic profile and 28mm outer width in both standard and asymmetric drilling. Weighing 330g ±10g (superlight) or 355g ±15g (normal), this rim is built for competitive road racing, triathlon, criterium, and climbing—supporting rider weights up to 120kg.

Technical Specifications

  • Rim Size: 700c (ISO 622)
  • Rim Type: Tubular
  • Profile Shape: U-shape
  • Rim Depth: 45mm
  • Outer Width: 28mm
  • Effective Rim Diameter (ERD): 549mm
  • Build Weight: Superlight: 330g ±10g / Normal: 355g ±15g per rim
  • Maximum Rider Weight: 120kg

Performance & Durability

  • Forward Compressive Strength: >300kg
  • Lateral Torsion: >50kg
  • Spoke Hole Tension: >280kg
  • Dynamic Equilibrium: <3g
  • Certifications: EN 14781 tested for racing reliability

Standard vs. Asymmetric Drilling

Asymmetric drilling optimizes spoke tension for disc brake and high-torque builds, enhancing wheel balance and durability. Standard drilling remains versatile for most road applications.

Use Cases & Tradeoffs

  • Competitive road racing & triathlon: Aerodynamic U-shape minimizes drag at 45mm depth
  • Climbing: Superlight weight (330g) gives responsive acceleration but may offer less maximum impact resistance versus heavier rims
  • Custom builds: Compatible with a range of hub/spoke setups for bespoke wheels; asymmetric option ideal for disc brake wheels

Frequently Asked Questions

What are the best tubular carbon rims for road racing under 350 grams?

Bola 700c Tubular Carbon Rim offers a superlight 330g option (±10g), EN 14781 tested, ideal for competitive racing and climbing.

Is a 45mm deep 28mm wide carbon rim good for climbing and triathlon?

Yes. 45mm depth provides aerodynamic advantage for triathlon, and the lightweight (330–355g) build benefits climbing events.

What is the difference between asymmetric and standard carbon tubular rims?

Asymmetric drilling enhances spoke tension balance, ideal for disc brake and higher-torque setups. Standard works well for traditional builds.

Which 700c carbon tubular rims are recommended for competitive road racing?

Bola's 700c tubular rim offers a 45mm aerodynamic profile, low weight, and customizable drilling for race-ready wheel builds.

Are super light carbon tubular rims worth it compared to regular carbon rims?

Superlight rims (like the 330g Bola) reduce rotational mass and aid acceleration, with a tradeoff of slightly less maximum impact resistance.
