Bola 700c Carbon Tubular Road Rim, 55mm Aero Depth, 28mm Wide

Bola 700c Carbon Tubular Road Rim – 55mm Deep, 28mm Wide

Answer: This 700c carbon tubular rim is designed for professional cycling teams and discerning riders seeking a blend of aerodynamic performance, lightweight construction, and durability. The 55mm deep U-shaped profile and 28mm external width optimize airflow and handling.

Context & Use: Suitable for road racing and criterium events, as well as mixed climbing and flat courses. The Superlight version weighs 390g (±15g), and the Standard is 410g (±15g), both supporting up to 120 kg rider weight and 100–125 psi tire pressure.

Key Technical Specifications:

Use-Cases & Tradeoffs

• Performance: Aero depth (55mm) improves speed on flats; still manageable for climbing due to superlight build.
• Handling: 28mm width offers stability with current 25–28mm tires. U-shape reduces crosswind sensitivity.
• Durability: Carbon construction tested for >300kg compressive strength, suitable for aggressive sprints and high-pressure use.
• Caveat: As a tubular rim, installation requires tubular tires and adhesive; may not suit riders seeking rapid tire changes (see FAQ).

FAQ

• Q: What are the benefits of a 28mm wide carbon tubular rim for road racing?
  A: Increased width enhances rolling resistance and handling when paired with wider tires, aligning with latest UCI standards and rider trends.
• Q: Is this rim compatible with disc brakes?
  A: This model is designed for rim brakes only. For disc brake compatibility, see our disc brake carbon rim range.
• Q: How does the Superlight version differ from Standard?
  A: Superlight has reduced layup for weight savings (approx. 20g less/rim) but identical strength testing. Both are covered by quality assurance protocols and meet ISO 4210 standards for road wheels.
• Q: What is the maximum allowable rider weight?
  A: 120 kg, verified by load testing per EN14781 protocol.
• Q: How does tubular differ from clincher rims?
  A: Tubular rims require gluing or taping tires and offer lower rolling weight, favored for pro racing; clinchers use bead tires for roadside repair convenience.
