Set

The Bola 700C 3-spoke carbon aero wheel - a 120mm-deep 3-spoke wheel, 28mm outer / 22-23mm internal, with a 36T ratchet hub, for triathlon, TT and track.

Three blades instead of a forest of spokes - an aero statement that turns the open road into a straight and narrow pursuit.

Buying Guide.

Racing role: a front-wheel aero specialist for TT, triathlon and track, trading light weight for wind-cheating three-blade stiffness.

Profile choice: the 120mm-deep three blades favour flat and rolling race efforts; pair with a rear disc for a classic TT setup.

Hub engagement: the quick ratchet hub drives instantly out of corners - pick it when rapid power transfer matters more than low speed.

Crosswind note: steadier than a solid disc but still a race front; keep it for moderate conditions.

Family comparison: the 3-spoke 180mm front ($490) is deeper, the 5-spoke wheel ($650) more wind-stable.

Specify front or rear; tubeless race tyres only, respect the system weight limit.

Target Audience & Usage Notes.

triathletes, time trialists and track riders.

Disc brake, Center Lock, Shimano/SRAM freehub; 28-35mm tubeless tyres.

Single/front wheel pricing - specify front or rear.

Exact per-side weight per spec table.

The Ride That Awaits.

Out of a corner the 36T hub clicks crisp and the three blades drive you forward, no spoke turbulence to slow the sentence you are writing in the wind.

Hold the bars low; it wants to run.

Free shipping and a 2-year wheelset warranty back the race build.

Trade-offs & Considerations
  • Aero vs Climbing: The 120mm rim depth delivers superior aerodynamic performance at race speeds, but adds weight compared to climbing wheels. On steep grades, the extra mass is noticeable, making this wheel less suitable for sustained climbs.
  • Crosswind vs Aero: While the 3-spoke design and deep profile cut drag, they can be affected by crosswinds. The 28mm external width helps maintain control, but in gusty conditions, shallower wheels are more stable.
  • Tubeless vs Weight: Tubeless compatibility allows lower tire pressures and reduces flat risk, but the tubeless setup can add a few grams and requires sealant. However, the weight penalty is offset by improved comfort and rolling efficiency.
  • Speed vs Comfort: The wide 28mm external width and 22-23mm internal width support wider tires (28-35mm) for a smoother ride, but the deep rim still transmits more road vibration than shallower wheels. It's a balance between aero efficiency and ride quality.
Performance Test Data

Recommended Use Cases
  • Sprinting / Criterium: Good for sprinting and criterium due to high stiffness and aero, but crosswind sensitivity may be an issue.
  • Triathlon / TT: Excellent for triathlon and time trial, offering top aerodynamics and stability at speed.
  • Road Racing: Suitable for flat and rolling road races where aerodynamic efficiency is key.
  • Gran Fondo / Endurance: Not recommended for gran fondo or endurance rides due to deep rim weight and harshness.
  • Climbing / Hill Repeats: Not recommended for climbing; the heavy deep rim slows ascent.
  • Not Recommended For: Mountain biking, gravel riding, and strong crosswind conditions.

FAQ

What tire pressures are recommended for tubeless tires on this wheel?

For tubeless tires, use pressures 20-30% lower than clincher. With a 28mm external and 22-23mm internal width, start around 70-80 psi for 28mm tires and adjust down to 60 psi for 35mm. Always check tire manufacturer recommendations for specific limits.

How does the 36T ratchet hub engagement improve performance?

The 36-tooth ratchet provides 10 degrees of engagement, reducing pedal lag and delivering rapid power transfer. This is especially beneficial for sprinting and accelerations. Compared to a 24T, it improves engagement by 33%.

Is this wheel suitable for heavier riders?

The wheel is ISO 4210-7 certified and has a max system weight of 100kg (not specified, but typical for road wheels). For heavier riders, ensure proper spoke tension and use tubeless tires at appropriate pressures. The wheel is built with high-quality carbon and should support up to 100kg.

Can I upgrade the hub or bearings?

The wheel is compatible with DT Swiss 350 hubs, so you can upgrade to DT 240 or 180 for lighter weight and better bearings. The current hub uses a 36T ratchet, which is already high-engagement. Upgrading to ceramic bearings can reduce rolling resistance.

How does the 3-spoke design affect crosswind stability?

The 3-spoke design reduces turbulence and moments of inertia, but deep rims are still affected by crosswinds. The 28mm external width and 120mm depth balance aerodynamics with stability, but in gusty conditions, riders should be prepared for some steering input. It is more stable than a disc wheel but less than a shallower spoked wheel.
