The Bola 700C 31mm 5-spoke carbon triathlon wheel - a 45mm-deep, 31mm-wide 5-spoke wheel with 25mm internal width and a 36T ratchet hub, for triathlon and TT.

Five blades wrapped around a wide, fast bed - a triathlon weapon that pairs aero five-spoke looks with the modern tyre volume long-course riders demand.

Buying Guide.

Racing role: a long-course triathlon front that blends five-blade aero with a wide, comfortable tyre bed.

Tyre choice: the wide internal bed suits 28-38mm rubber - run wider, lower-pressure tyres for Ironman comfort, narrower for pure speed.

Hub engagement: the quick ratchet hub transfers power instantly out of transitions and corners.

Family comparison: the 28mm 5-spoke wheel ($650) uses a narrower bed for classic race rubber; the 6-spoke wheelset ($650) is a complete wide aero pair.

Front wheel; tubeless tyres, respect the system weight limit.

Target Audience & Usage Notes.

long-course triathletes and TT riders wanting a wide, comfortable aero front.

Front wheel, 12x100, Center Lock disc (rim-brake option). 29-44mm tubeless tyres. 120kg system weight.

Trade-offs & Considerations
Aero vs Crosswind: The molded five-spoke aero profile saves about 3.5W versus a 35mm laced wheel at 40km/h; at 10° yaw the solid spoke disc keeps steering linear in gusts, while the 45mm depth still carries a higher crosswind signature than a 35mm rim.
Weight vs Stiffness: The one-piece five-spoke structure is about 20% laterally stiffer than a 24-spoke laced build at the same 45mm depth (±5g in claimed weight); the fixed spoke layout removes spoke-by-spoke tension tuning in exchange for that stiffness.
Tire-Type Trade-off: The hooked bed mounts clincher and tubeless tyres from about 28c to 38c on the 25mm inner width; tubeless runs lower pressure and cuts rolling resistance but needs tape, valve and sealant, while clinchers use a removable inner tube.
Sourcing & Delivery Trade-off: Stock build ships in 1–3 business days at $650; custom decals or a front-only build add 7–15 business days and roughly a $50–100 premium over the standard listing.
Config Ladder: The molded five-spoke carbon structure is fixed, with no steel-to-carbon spoke upgrade ladder; the HG freehub is standard with XDR and XD selectable at checkout, and mixing a five-spoke front with a laced rear is the only position-level build option.

FAQ
Which tyres fit and what pressure should I run on the 25mm internal bed?
The 25mm internal bed suits 25–38mm tubeless tyres — 80–100 PSI for 25–28mm and 60–80 PSI for 30–38mm.
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.
Can I swap the freehub to fit my cassette?
The hub is built on a DT Swiss 350 standard, so the freehub can be swapped to match Shimano or SRAM; note your groupset at checkout and we set it up.
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.
