Hookless rims are modern bicycle wheel rims (mostly carbon fiber) that do NOT have the small curved “hook” on the edge that traditional (hooked) rims use to hold the tire in place.
Instead of a mechanical hook, they use:
- a straight, smooth sidewall
- a tight, precision fit (following ETRTO standards) between the rim and tire bead
- air pressure (tubeless system) to keep the tire securely seated
They are designed only for tubeless tires and have become the standard for high-end road, gravel, and performance carbon wheels.
Key Benefits (simple bullet points)
- Stronger & more durable: No weak hook point = better resistance to impacts, cracks, and dents.
- Lighter: Less carbon material = lower rotational weight for faster acceleration.
- More aerodynamic: Smooth sidewall improves airflow at speed.
- Easier tubeless setup: Tires mount smoother with less pinching or struggle.
- Perfect for wide tires: Works great with modern 28c–50c road/gravel tubeless tires.
Important Rules (must-know for safety)
- Only use hookless-compatible tubeless tires (marked on the tire).
- Do NOT use standard clincher tires + inner tubes (unsafe, not reliable).
- Always follow the brand’s max pressure limit (usually 60–100 PSI / 4–7 bar).
Who are they for?
- Road cyclists (endurance, racing, aero)
- Gravel riders (best choice for rough terrain)
- Riders who use tubeless tires only
- Anyone wanting lighter, stronger carbon wheels
