Trade-offs & Considerations
- Aero vs Climbing: 40mm depth balances aero gains with light weight (375-430g) – good for climbs and flats.
- Weight vs Durability: Ultralight 375g option reduces rotational mass but may be less durable than 430g standard version.
- Tire Volume vs Speed: 24mm inner width for narrower tyres (25-28mm) prioritises speed; 25mm inner width allows 25-32mm tyres for comfort.
- Crosswind vs Aero: 40mm depth offers moderate aero benefit with manageable crosswind behaviour compared to deeper rims.

FAQ
What tubeless setup is recommended for this rim?
Use tubeless valves and sealant (20-30ml per tire). Ensure compatible tires with 24mm/25mm inner width. Maximum pressure is typically 110-120 psi for 700c road setup.
What tire widths can be used?
With 24mm inner width, use 25-28mm tires; with 25mm inner width, use 25-32mm tires. Always check tire manufacturer's minimum/maximum width range for the rim inner width.
How much weight can be saved compared to aluminum rims?
This carbon rim weighs 375-430g depending on weight tier, which is 200-300g lighter than a typical aluminum rim (around 600-700g). This reduces rotational mass and improves acceleration.
Can this rim be used for custom wheel builds?
Yes, it is designed for custom builds. Spoke hole tension exceeds 300kg, and the rim is compatible with standard spokes (e.g., DT Swiss, Pillar). Wheel builders can lace it to hubs of their choice.
How should I maintain and inspect the rim?
Regularly check for cracks, impact damage, and brake surface wear (if rim brake). For tubeless, inspect sealant level every few months. Carbon rims can be susceptible to heat damage from long descents with rim brakes; monitor brake pad temperature.
