A 60mm deep four-spoke monocoque carbon wheelset in tubeless or tubular options, 1550–1920g depending on config, for road, track and triathlon.

Four-Spoke Race Platform

The Bola four-spoke wheelset concentrates material for high torsional stiffness and a steady crosswind feel. Available in tubeless or tubular rim options across road, track and time-trial configurations, it balances aero stability with weight efficiency.

Buying Guide.

Configuration - tubeless or tubular: tubular saves weight but needs gluing; tubeless is the practical, repairable daily.

Configuration - road or track: road for time trial and crit, track for the velodrome; pick the build that matches your event.

Hub - 36T ratchet at ten degrees: quick pickup for sprints and attacks.

Tire width - narrow bed: 25-32mm tires; it is a classic aero-width rim, not a wide gravel platform.

Same family - the 6-spoke Bola wheelset goes further on aero and certification; four spokes favor crosswind composure.

Target Audience & Usage Notes.

Road racers, time trialists, triathletes, and velodrome riders.

Not for general training on rough roads.

The Ride That Awaits.

Settle into the bars and let those four wide blades shoulder the crosswind aside - the 36T ratchet picking up power on the very first degree of rotation, ceramic bearings humming as the road unspools. It is poise in a storm, speed on a flat. A 2-year warranty and free shipping let you commit to road, track or tri.

Trade-offs & Considerations
Aero vs Crosswind: The 60mm depth saves about 6.5W versus a 40mm wheelset at 40km/h; at 10° yaw the solid four-spoke disc profile demands calmer steering input in gusts than a 38–40mm laced set, which is the trade-off of its time trial speed.
Weight vs Stiffness: The T1000 layup keeps the 60mm rim laterally stiff within 3%; the tubular build starts at about 1550g, roughly 200g lighter than the tubeless-clincher version of the same rim (±5g).
Tire-Type Trade-off: Glue-on tubulars give about 8% lower rolling resistance than clincher tubeless, but the tyre is glued: service the bond every 3–6 months, no roadside puncture repair and no sealant-based flat prevention.
Sourcing & Delivery Trade-off: Build to order only: 7–15 business days with no stock option; the $650 entry price is low versus mass-produced aero sets, and the custom build time is the cost of the hand-built tubular bond.
Config Ladder: The BL 240 36T ratchet hub with Enduro steel bearings is standard; moving to ceramic bearings cuts about 1.5W of hub friction for around +$120; Sapim CX-Ray spokes stay fixed at 24/24 2-cross, and the HG freehub has XDR as a selectable option.

FAQ
Do I need special glue and what comes with these tubular wheels?
These are tubular wheels, so the tyres glue on with tubular cement; the box includes the valves and spare spokes, and the hooked bed is optimized for tubular setups.
Will this wheelset fit my groupset?
It is built on a Shimano HG freehub out of the box; note your groupset at checkout if you need a different driver.
How does this deep rim handle crosswinds on descents?
An optimised profile keeps steering torque predictable at 10°–15° yaw, so high-speed descents stay planted.
If my wheel is badly damaged in extreme riding, am I covered?
Yes — beyond the 2-year factory warranty, you get lifetime 30% Crash Replacement: a discounted replacement wheel without paying full price.
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, delivered to your door with no extra payment to customs or the courier.
