Bola 700c Asymmetric 30mm Carbon Gravel Rim - Designed for gravel, endurance and all-road builds

The 30mm outer width gives strong tire sidewall support for 32–54mm gravel and all-road tires, improving stability and confidence on rough surfaces and fast descents. The asymmetric 2.6mm offset and low-profile V-shaped Toray T700/T800 carbon construction are engineered to deliver better spoke tension balance and a durable rim bed that accommodates tubeless setups and a wide range of tire widths.

Why it fits your routine

• Multiple weight tiers: Select Normal (405±15g), Superlight (365±10g), or Ultralight (335±10g) per rim to tune rotating weight versus load capacity for endurance, racing, or climbing-focused builds.
• Proven strength and reliability: EN 14781 compliant and tested to greater than 300kg forward compressive strength and greater than 280kg spoke tension for demanding use.
• Tubeless-ready versatility: Hookless tubeless-compatible bead verified with standard 6.5mm tubeless valves, supporting tubeless or clincher tires from 32mm to 54mm wide.
• Rim dimensions tailored for gravel: 30mm outer width, available 24mm or 25mm inner width, 30mm depth—designed to support larger-volume gravel tires with stable sidewall support.
• Asymmetric design benefits: 2.6mm offset improves spoke bracing angle and tension balance for stronger, longer-lasting wheels, especially in disc-brake applications.
• Build flexibility: Custom spoke drilling available for straight-pull or J-bend spokes with a 4.5mm nipple seat to suit a wide range of hub and lacing choices.
• Material quality: Constructed from Toray T700/T800 carbon fiber composite for a light, high-strength rim platform appropriate for gravel, endurance, and all-road wheel builds.
• Warranty and support: Three-year warranty against manufacturing defects provides assurance for long-term use.

Recommended use aligns with rider weight and intended discipline: the Normal tier supports higher-load endurance, bikepacking, and riders up to approximately 120kg; the Superlight tier is aimed at all-day gravel racing and mixed-terrain events for riders up to about 100kg; the Ultralight tier suits climbing-focused competitive builds with an approximate 80kg rider guidance. The rim fits 700c / ISO 622 bikes and is compatible with common tubeless setups and a broad range of gravel tires, making it suitable for custom wheel builds where balancing durability and weight is a priority.
