Couldn't load pickup availability
A 50mm V/U-shaped hookless-compatible carbon road rim with 36/30mm widths, tubeless-ready, and four weight tiers 395–490g.
Focused Aero, Modern Tire Width
The BOLA 50mm road rim pairs a deep aerodynamic profile with a 36mm external and 30mm internal width for modern 35c–48c road tires. The V/U-shaped hookless-compatible profile supports tubeless setups with proper tape and valves.
Buying Guide.
Weight tier - Extreme Light ~395g: lightest build for smooth-road racers.
Weight tier - Ultralight ~410g: climbing with aero aspirations.
Weight tier - Superlight ~450g: balanced all-round.
Weight tier - Normal ~490g: the durable, higher-load choice.
Depth - deep aero: a flat-course weapon; in wind or on climbs it demands more respect than the shallower Bola rims.
Build - disc frames only: plan extended valves for the deep section.
Target Audience & Usage Notes.
Road racers, triathletes on flat/rolling courses, and criterium riders.
Not for steep climbs where minimal weight is critical.
The Ride That Awaits.
Drop onto the drops and hold the line - that deep V-section carries speed like a secret, the wide bed swallowing 35-48c tires so the rough road stops mattering and only the forward push remains. It is purposeful, composed, fast. Backed by a 3-year warranty with crash cover and free shipping, it is ready when you are.

Translation missing: en.product.metafields.tradeoffs
- Aero vs Weight: The 50mm depth provides a measurable aero advantage at higher speeds, but the Extreme Light tier at 395g sacrifices minimal rotating mass, while the Normal tier at 490g offers more material for durability.
- Crosswind vs Aero: Deep 50mm rims can be lively in crosswinds, but the wide 36mm external width and V-shaped profile help mitigate this, balancing aero gains with stability.
- Tire Volume vs Speed: Wider 30mm internal width supports 25-32c tires, improving rolling efficiency and comfort, but may slightly increase aerodynamic drag compared to narrower rims.
- Weight vs Durability: The Extreme Light tier at 395g reduces rotating mass for climbing, but the Normal tier at 490g provides more material for durability; lighter options may have tighter tolerances and could be more susceptible to impact damage.

Is this rim tubeless-ready and how do I set it up?
Yes, it is tubeless-ready. Use tubeless rim tape, tubeless valves, and sealant. The rim has a hookless-compatible profile, so ensure your tires are hookless-compatible. Recommended pressure is 100-125 psi, and you may need extended valve stems due to the 50mm depth.
What tire widths are compatible?
The 30mm internal width is optimized for modern road tires, recommended range is 25c-32c. This provides improved casing profile for rolling efficiency and puncture resilience.
What are the weight options and how much can I save?
The rim is available in four weight tiers: Normal (490±15g), Superlight (450±10g), Ultralight (410±10g), and Extreme Light (395±10g). Depending on your choice, you can save up to 95g per rim compared to the heaviest option.
Can I customize the build with my own spokes and hubs?
Yes, the rim supports standard spoke counts typically 24h or 28h, and you can customize assembly hole diameters, valve hole, and spoke hole sizes. ERD is 538mm, and nipple bed angles are 7° front and 5°/7° rear (customizable).
What maintenance and inspection is needed?
Regularly inspect for impacts or cracks, especially after hard rides. Check spoke tension and trueness. The rim has dynamic equilibrium below 3g to assist trueness. Since it's a disc brake rim, brake heat is not a concern, but always ensure proper torque on rotor bolts.
