The Bola 700C carbon 6-spoke wheelset - a 50mm-deep, 42mm-external / 32mm-internal wide aero wheelset with a 36T ratchet hub, ~655g front / ~770g rear, for TT, tri and aero road.

Six structural blades spanning a remarkably wide bed - a 6-spoke that marries wind-tunnel-proven aero with the wide-tyre comfort modern riding demands.

Buying Guide.

Racing role: a wide, complete aero wheelset for aero road, fast all-road and TT - six structural blades on a broad tyre bed.

Tyre choice: the wide internal bed suits 32-48mm rubber - 32-40mm at moderate pressure for fast mixed surfaces, 40-48mm lower for rough terrain.

Hub engagement: the quick ratchet hub and choice of freehubs suit surging and modern 12-speed drivetrains.

Family comparison: the 5-spoke wheel ($650) is a front-focused narrower option; the four-spoke wheelset ($650) is a different blade count.

Not a narrow-climbing race wheel; respect the system weight limit.

Target Audience & Usage Notes.

aero road, TT/triathlon and fast all-road riders wanting a wide, one-wheelset solution.

Disc brake, Center Lock; choose Shimano HG / XDR / Microspline and axle at checkout. 32-48mm tubeless tyres.

Not a narrow-climbing race wheel.

The Ride That Awaits.

Spin it up and the six blades hum with a stiff, purposeful note; undress the wind and the wide bed swallows rough surfaces, turning them into long, fast glides.

It feels built to keep going, mile after mile, for you.

Free shipping and a 2-year wheelset warranty round it out.

Specifications

Inner Rim Width: 32mm
Outer Rim Width: 42mm
Hub Model: BL 200 36T
Spoke: Carbon
Bearing Type: Enduro Steel
Complete Wheelset Weight: 1400-1425g (tape & valve excluded, ±2% tolerance)
Accessories: N/A
Trade-offs & Considerations
Aero vs Crosswind: 50mm depth saves about 4.5W versus a 40mm wheel at 40km/h; the 42mm outer width keeps the aero gain, but crosswind response at 10° yaw is more sensitive than a shallow 30mm rim.
Weight vs Stiffness: 1400–1425g for the set; bladed Pillar 1420 spokes and the carbon layup deliver high lateral stiffness for sprint power transfer, and the lightest build holds within 5g of 1400g.
Tire-Type Trade-off: The hooked bed runs clincher and tubeless tyres; the 32mm internal width suits 40–50c gravel volumes at 40–50 psi rather than narrow road tyres.
Sourcing & Delivery Trade-off: Stock build ships in 1–3 business days at $650; custom decals or lacing add 7–15 business days and roughly a $100 premium.
Config Ladder: The BL 200 36T ratchet hub is standard; moving steel to ceramic bearings cuts about 1.5W of hub friction for around +$120; a DT 240 hub upgrade adds about +$250.

FAQ
Which tyres fit and what pressure should I run on the 32mm internal bed?
The 32mm internal bed suits wide tubeless tyres; a 32mm tyre commonly runs at 70–80 PSI, then tune to your weight and the roads.
Will this wheelset fit my groupset?
It ships on a Shimano HG freehub; note your groupset at checkout if you need SRAM XDR or Microspline.
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.
