The Bola 700c asymmetric carbon rim — a 35mm-deep, 24mm-internal hoop (330-400g) built for gravel, cyclocross and all-road.

An asymmetric spoke bed equalizes tension for stiffer, longer-lasting wheels under disc load. At 35mm deep and 24mm inner, this Bola rim balances aero with crosswind calm for mixed surfaces.

Buying Guide.

Weight tier - Extreme Light ~330g: the Ultralight race build - for gravel racers and gran fondo climbers who want the lightest hoop.

Weight tier - Ultralight ~350g: the fast middle - a few grams more for training without losing the climb.

Weight tier - Superlight ~370g: the race-and-training balance.

Weight tier - Standard ~400g: the Light-grade durability build - rougher roads and loaded riders who want margin.

Internal width - 24mm: a balanced gravel/all-road channel that beds 27-42mm tires at moderate pressure - choose it for mixed surfaces rather than deep aero.

Same-family: the 30mm gravel rim ($310) is shallower and comfort-focused; the 40mm gravel rim adds aero on fast sectors.

Rated to a 105kg system weight.

Target Audience & Usage Notes.

Gravel racing, cyclocross, gran fondo and training.

Max system weight 105kg; not deep-aero racing; disc only.

The Ride That Awaits.

Drop the tire pressure and feel the gravel disappear under you - the offset bed holds tension true on chipseal and settles fast in crosswinds. It tracks predictably over rough miles, staying round where lesser hoops go out of true. Choose your weave and layup; a 3-year rim warranty and factory-direct shipping mean you simply ride.

Trade-offs & Considerations
Aero vs Crosswind: The 35mm depth saves about 2.5W versus a 28mm rim at 40km/h; at 10° yaw the asymmetric 30mm outer width keeps the side-wind signature low, making it a balanced road-gravel section rather than a pure aero deep rim.
Weight vs Stiffness: The Extreme Light tier (330g) saves about 70g versus the Standard tier (400g) at the same 35mm depth (±5g); lateral stiffness holds within 3% across tiers, and the asymmetric drilling evens spoke tension left and right.
Tire-Type Trade-off: The hooked bead accepts clincher and tubeless tyres from about 28c to 45c on the 24mm inner width; tubeless runs lower pressure on gravel but needs tape, valve and sealant, while road setups can run down to 25c.
Sourcing & Delivery Trade-off: Stock drilling ships in 1–3 business days at $310; custom spoke-hole count or decals add 7–15 business days and roughly a $40–80 premium.

FAQ
Which tyres fit on the 24mm inner rim, and what pressure suits me?
The 24mm inner width supports 32mm–50mm gravel and cyclocross tyres; on road you can drop to 25mm, and the hooked bed takes clincher and tubeless directly.
How do I work out the right spoke length for this rim?
Contact Bola for the exact ERD before ordering spokes. Once we confirm the figure, plug it into a known calculator (Sapim / DT) and add the recommended correction.
What is the maximum spoke tension I can run on this rim?
Drive-side / disc-side max tension is 130–140 kgf, with the non-drive side adapted to match; spoke holes are locally reinforced inside the carbon layup to prevent pull-out cracking.
Will the rim crack on rock gardens or bottom-outs at low pressure?
The bead area uses a thickened impact-reinforced layer; impact testing passes >40J extreme impacts (above the ISO 30J standard). Inner widths of 24mm accept wider tyres, which deform to absorb shock at low pressure.
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.
