FAQs

  • Q: What are the main advantages of an asymmetric rim design?
    A: Asymmetric rims balance spoke tension for increased wheel durability and reduce lateral flex in disc brake setups, compared to symmetric designs.
  • Q: When should I use hookless vs. hooked bead?
    A: Hookless beads support lower tire pressures and reduced weight; hooked beads allow a wider tire pressure and standard clinchers. Always verify tire compatibility for hookless use above 70psi.
  • Q: Is the Bola 45TR28 suitable for long distance or racing?
    A: Yes. Its low weight and aerodynamic profile make it ideal for endurance, race, and high-performance urban builds.
  • Q: How does it compare for safety at sub-400g weights?
    A: All rim weights meet ISO 622 and dynamic balance testing. Extreme-Light (375g) is best for riders ≤85kg and smooth surfaces.
  • Q: What tire sizes and pressures are supported?
    A: Designed for 25–32mm tubeless tires, up to 125psi (hooked) or 100psi (hookless as per ETRTO guidelines).
