700c Asymmetric Carbon Gravel Rim, 30mm Wide – Technical Details & Use Cases
Lead Answer: Bola’s 700c asymmetric carbon gravel rim delivers a 30mm outer width and is offered in normal (405g), superlight (365g), and ultralight (335g) weight tiers. Designed for riders and brands prioritizing high-performance, lightweight construction, and durability in gravel and mixed terrain builds. EN 14781 compliant and tested to >300kg compressive strength.
Key Specifications

- Available weights: 405±15g (normal), 365±10g (superlight), 335±10g (ultralight)
- Offset: 2.6mm asymmetric
- Tubeless compatible: Yes (hookless bead, verified with standard 6.5mm tubeless valves)

Weight Tier Comparison & Use Cases
| Tier | Weight per Rim | Best For | Rider Weight Limit |
|---|---|---|---|
| Normal | 405±15g | Endurance gravel, bikepacking, heavier loads | ≤ 120kg |
| Superlight | 365±10g | All-day gravel racing, mixed terrain, fast handling | ≤ 100kg |
| Ultralight | 335±10g | Competitive climbing, lightweight builds | ≤ 80kg (best performance) |
Tradeoff: Ultralight saves 70g per rim but has stricter weight and terrain limitations; Normal tier offers maximum stability for high-load scenarios.

Frequently Asked Questions
-
Q: Is a 30mm wide carbon rim better for gravel?
A: A 30mm rim optimizes stability and tire support for 32-54mm gravel tires, enhancing control on mixed terrain compared to narrower rims. -
Q: What is the difference between superlight and ultralight tiers?
A: Ultralight rims prioritize the lowest possible weight for climbing and racing at the expense of max rider weight and terrain toughness. Superlight balances racing agility with broader use-case and durability. -
Q: Why choose an asymmetric carbon rim?
A: Asymmetric offset (2.6mm) improves spoke bracing angle, equalizing tension for a stronger, longer-lasting wheel—especially important for disc-equipped gravel bikes. -
Q: How much does a quality 700c gravel carbon rim weigh?
A: Industry norms range from 335g (ultralight) to 405g (endurance/all-purpose), slotting this offering among the lightest EN-certified options.
