Frequently Asked Questions

What tubeless carbon rims are best for road cycling at 40mm and 25mm width?
This rim meets ETRTO standards, verified at 375–430g, and provides performance for racing and long-distance rides.
Should I choose hookless or hooked for my road tubeless setup?
Hookless supports modern tubeless, up to 72 psi with compliant tires. Hooked offers broader tire compatibility with traditional road clinchers.
Is sub-400g rim weight suitable for racing?
375–395g tiers minimize rotational weight for rapid acceleration, preferred by climbers and racers; consider tire fit for your use case.
What’s the advantage of 24mm vs 25mm internal width?
25mm allows wider tires for comfort and stability on rougher roads or ultradistance rides; 24mm prioritizes aero efficiency for road racing tires.
What tire sizes are recommended?
24mm inner: 25–28mm tires; 25mm inner: 25–32mm tires (see ETRTO guidelines).
