Bola 700C Asymmetric Tubular Carbon Road Rim Overview
Designed for professional teams, custom builders, and competitive cyclists, the Bola 700C asymmetric tubular carbon road rim offers a blend of aerodynamic efficiency, weight savings, and balanced spoke tension. The 30mm deep U-shape profile and 28mm outer width support improved tire interface and stability, while the asymmetric drilling corrects spoke tension differences common in cassette-side dished wheels. Each rim is crafted from premium unidirectional carbon fiber in a matte black finish, resulting in a verified rim weight of 285 ±10g (standard build: 305 ±15g).

- Fits 23–28C tubular tires. See size guide for compatibility with common tire models.
FAQs
Q: Is a 30mm deep carbon rim versatile for both climbing and flat sections?
A: Yes. A 30mm depth strikes an aerodynamic and weight balance, making it suitable for varied race profiles—climbs and fast flats.
Q: Why choose asymmetric over symmetric carbon rims?
A: Asymmetric designs help equalize left-right spoke tension, minimizing stress and extending wheel life—especially in rear wheels with cassette offset.
Q: What is the typical weight for a superlight tubular carbon road rim?
A: Industry norms range 280–350g for high-end tubular road rims. Bola’s verified 285g is among the lightest documented for 700C/30mm depth options.
Q: Tubular vs. clincher carbon rims—which for road racing?
A: Tubular carbon rims remain preferred for elite racing due to lower weight and better ride feel, though clinchers provide convenience. Bola’s tubular is aimed at performance-focused use.
