Field Road Track

A 55mm three-spoke monocoque carbon front wheel, 28mm outer / 21–22mm inner, 800g, CenterLock disc or track hub, for TT, triathlon and track.

Closed-Course Aero Front

The Bola three-spoke front wheel reduces turbulent airflow and delivers direct power transfer for sustained high-speed efforts. Its 28mm external width improves crosswind stability and supports 25–32mm tubeless, clincher or tubular tires.

Buying Guide.

Bed - hooked or hookless: hooked broadens tire choice; hookless trims weight and rolls faster; pick by your tire.

Hub - CenterLock disc or track: build it for a disc time-trial bike, or a track hub for the velodrome; no rim-brake road variant.

Spoke design - 3-spoke monocoque: no truing, no spoke replacement; buy it as a sealed closed-course front.

Tire width - 25-32mm: favor narrower for aero, wider for comfort and grip.

Same family - Bola's longer 3-spoke front goes deeper for pure flat-course aero; this shallower member is the more crosswind-manageable choice.

Target Audience & Usage Notes.

Triathletes, time trialists, and track/velodrome riders on closed courses.

Not for climbing, rough roads, or technical descents.

The Ride That Awaits.

Picture the first pedal stroke: three monocoque blades slice the wind in one clean cut, no spokes to flutter, no truing to obsess over. On a closed course it holds its line wide and calm, built for a disc time-trial bike or the boards of the velodrome. A 2-year wheelset warranty with crash-replacement means you ride it hard and order it without second thoughts.

Trade-offs & Considerations

Aero vs Crosswind: The monocoque 3-spoke front at 55mm depth saves about 6W versus a 40mm laced front at 40km/h; the solid aero arms push more at 10° yaw than a bladed-spoke front.

Weight vs Stiffness: 800g for the front; the single-piece construction is very stiff laterally and never needs truing, traded for a firmer ride over rough surfaces.

Tire-Type Trade-off: The 21mm hooked (22mm hookless) internal bed runs tubeless 25–32c at 80–100 psi; tubeless needs tape, valve and sealant to seal the bed.

Sourcing & Delivery Trade-off: Stock ships in 1–3 business days at $530; custom options add 7–15 business days and roughly a $50 premium.

Config Ladder: Choose a center-lock disc or track hub; both run the 36T ratchet at about 10° engagement; Enduro steel bearings are standard and a ceramic upgrade cuts about 1.5W of friction for around +$120.

Recommended Use Cases

Sprinting / Criterium: Good - stiff and responsive, but aero advantage may be less relevant in tight corners.

Triathlon / TT: Excellent - designed for maximum aerodynamics.

Road Racing: Good - aero benefits help solo breaks, but heavier than climbing wheels.

Gran Fondo / Endurance: Suitable - but stiff ride and weight may not be ideal for long comfort.

Climbing / Hill Repeats: Not recommended - heavy for climbing.

Not Recommended For: Rough roads and technical descents due to stiffness and crosswind sensitivity.

FAQ

Will this three-spoke front wheel fit my center-lock disc road or time-trial bike?

Yes — the hub is set up for a Center Lock disc rotor; a 36-hole track hub option is also available for velodrome riding.

How does a deep aero rim handle crosswinds — will it tug the steering on fast descents?

An optimised aero profile keeps steering torque predictable at 10°–15° yaw, so high-speed descents stay planted and controlled.

Can I run standard clincher tyres, or do I need a hookless-specific tyre?

The rim is hooked, so standard clincher tyres fit directly; for tubeless setups the hooked bed seals reliably.

Is it built only for road and time-trial use, or can I ride it on the track too?

It works on road, time-trial and triathlon bikes; choose the track hub option if you also ride the velodrome.

Will I really pay no customs or VAT for delivery to the US and EU?

Yes. The Economy channel ships DDP — duties and VAT are fully prepaid by us, cleared in advance, and delivered to your door with no extra payment to customs or the courier.
