Bola Elite T800 Carbon Disc Brake Wheelset — Quick Answer
The Bola Elite is a Toray T800 carbon wheelset built for climbers and road racers who need sub-1,500g rolling weight without sacrificing disc brake compatibility. It ships with a 54-tooth engagement ratchet hub and aerodynamic straightpull carbon spokes across five rim depths (35–60mm), making it one of the most configurable performance wheelsets in its price bracket.

Technology Explained
54T Ratchet Hub
A 54-tooth ratchet system delivers a 6.67° engagement angle — meaning power transfers to the drivetrain within roughly one-tenth of a crank rotation. This is measurably faster than standard 36T hubs (10° engagement) and is particularly advantageous in criterium accelerations and technical climbs where instantaneous torque matters.
Straightpull Carbon Spokes
Unlike J-bend spokes, straightpull spokes eliminate the elbow stress point — the most common site of fatigue failure on high-load race wheels. Combined with carbon construction, this reduces aerodynamic drag per spoke while maintaining lateral stiffness. Note: Straightpull spokes require a compatible hub and are less universally serviceable than J-bend at local bike shops.
Toray T800 Carbon
T800 fiber offers a tensile strength of approximately 5,490 MPa and a tensile modulus of 294 GPa — a higher strength-to-weight ratio than the more common T700 fiber. This allows thinner layups at equivalent load ratings, directly contributing to reduced rim weight.
Known Tradeoffs
- Spoke serviceability: Straightpull carbon spokes are not available at most local bike shops. Carry a spare spoke for multi-day events.
- Deeper rims in crosswinds: The 50mm and 55mm profiles offer peak aerodynamic efficiency but require more active steering input in sustained crosswinds above ~35 km/h. Riders under 65kg may prefer the 40mm for mixed-terrain events.
- Disc brake only: These rims are not compatible with rim brake calipers.
Frequently Asked Questions
What rim depth is best for all-around road cycling?
The 40mm depth is the most versatile choice for riders who mix climbing, endurance rides, and moderate flat sections. It offers measurable aerodynamic improvement over a 35mm rim while remaining manageable in variable wind conditions.
Is the 54T ratchet hub worth it for competitive road racing?
For criteriums, punchy climbs, and sprint finishes, yes. A 54T system engages in 6.67° versus 10° on a 36T hub — a real advantage when accelerating from a corner or responding to an attack. For steady-state endurance riding, the benefit is less pronounced but the hub adds no weight penalty.
Are straightpull spokes more durable than J-bend spokes?
In controlled testing environments, straightpull spokes show lower fatigue failure rates at the spoke-to-hub interface because they eliminate the bent elbow stress concentration. However, carbon straightpull spokes require manufacturer-specific replacements, which affects field repairability.
What tire width is compatible with the 21mm and 24mm internal rim widths?
The 21mm internal width optimally pairs with 25–32mm tires. The 24mm internal width is recommended for 28–38mm tires. Both widths conform to the ETRTO 2020 guidelines for tubeless-ready setups.
Does this wheelset come tubeless-ready?
Please confirm with the seller whether tubeless tape and valves are included. The 21mm and 24mm internal widths are geometrically compatible with tubeless tire installation on appropriate rim beds.
