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 Crosswind: The 120mm 3-spoke monoblade profile is built for flat-out aero: it saves about 12.0W versus a 50mm spoked rim at 40km/h, but at 10° yaw the deep section and fixed blade make steering noticeably twitchier in crosswinds on open roads.
Weight vs Stiffness: The carbon monoblade structure is laterally very stiff under sprint and track watts, and there is no spoke tension to true; the trade-off is a higher weight than a conventional bladed-spoke wheel at this depth, traded for total power transfer.
Tire-Type Trade-off: The hooked bed accepts clincher and tubeless tires from about 25c to 32c; tubeless cuts rolling resistance and lets you run lower pressure, but needs tape, valve and sealant to seal the bed.
Sourcing & Delivery Trade-off: The stock build ships in 1–3 business days; a custom decal or hub option adds 7–15 business days and roughly a $60–100 premium.
Config Ladder: The sealed steel bearings already run smooth; moving to ceramic bearings cuts about 1.5W of hub friction for around +$100, and running a 28c tire instead of a 32c tire trades a little comfort for a touch more aero.

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
Which tyres fit and what pressure should I run on the 22–23mm internal bed?
The 22–23mm internal bed suits 28c–35c tubeless tyres; start near 70–80 PSI for a 28c and step down toward 60 PSI for a 35c, then tune to your weight.
Will this wheel work with my road cassette?
The 36T ratchet hub takes a standard road freehub; just tell us your groupset at checkout and we build on the matching 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.
Do these rims accept standard clincher tyres, and is there a pressure cap?
Hooked rims fit standard clincher tyres directly, no hookless pressure cap applies.
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.
