60mm vs 65mm Depth — Which Should You Choose?
- 60mm: Lower crosswind sensitivity; suited to mixed-terrain road racing, gran fondo, and riders in variable wind conditions.
- 65mm: Greater aerodynamic advantage at speeds above 40 km/h; preferred for triathlon, time trial, and flat-course racing where crosswind risk is managed.
Wave Aero Profile — What It Means
The wave aero (toroidal) rim wall creates a smoother airflow reattachment point compared to a flat-wall U-shape rim. This geometry reduces aerodynamic drag at yaw angles typically encountered during road and triathlon racing (5°–15° yaw). Note: aerodynamic advantage is most measurable above 35–40 km/h; at lower average speeds, weight savings from the Ultralight tier typically provide a greater performance return.
Tubeless Compatibility
The 22mm inner width accepts tires from 25mm to 32mm in tubeless or clincher configuration. The rim bed, valve hole diameter (6.5mm, customizable), and assembly hole (7.5mm, customizable) are designed for standard tubeless valve stems and tape installation.
Customization Options
- Spoke hole diameter: standard 4.5mm or custom
- Valve hole diameter: standard 6.5mm or custom
- Assembly hole diameter: standard 7.5mm or custom
- Nipple angle: Front 7°; Rear 5°, 7°, or custom
- Rim height: 60mm or 65mm
- Weight tier: Normal, Superlight, or Ultralight
Frequently Asked Questions
- What is the actual weight of the ultralight version?
- The Ultralight tier weighs 430 ±10g per rim (420–440g), verified per-unit at the factory before shipping.
- Are these rims tubeless-ready out of the box?
- Yes. The rim bed is tubeless-compatible. You will need tubeless tape, a valve stem, and tubeless sealant, which are not included.
- Is a 60mm or 65mm rim better for triathlon and time trial?
- The 65mm depth offers greater aerodynamic benefit on flat, controlled courses. The 60mm depth is the more versatile choice if your event includes variable wind or slight elevation.
- What tire widths are compatible with the 22mm inner width?
- ETRTO guidelines recommend tires 1.4× to 2.4× the inner rim width. For a 22mm inner width, this translates to approximately 25mm–50mm tires; for road use, 25mm–32mm is the practical range.
- What is the maximum rider weight?
- The rim is rated for riders up to 120 kg combined system weight (rider + bike + gear).
- Can spoke count and hole configuration be customized?
- Yes. Contact Bola directly with your spoke count, lacing pattern, and nipple angle requirements before ordering.
- What warranty does Bola offer?
- Bola provides a three-year manufacturer's warranty covering manufacturing defects in materials and workmanship.
