The Bola 700C V-section carbon gravel/cyclocross rim — a 35mm-deep, 30mm-wide disc hoop (330-400g) built for gravel and CX.

Stable across the rough: a 35mm V-section delivers a steady shape on exposed gravel sectors and crosswinds, while a 30mm outer width supports modern wide tires.

Buying Guide.

Weight tier - Ultralight ~330g: the gravel-race and CX build for lighter riders who want spin-up speed.

Weight tier - Superlight ~360g: the race-and-training balance.

Weight tier - Standard ~400g: the Light-grade durability build for rough gravel and loaded miles.

Internal width - 24mm hooked: a broader 27-42c platform - choose it for tube compatibility and a slightly faster feel.

Internal width - 25mm hookless: a wider 29-44c low-pressure platform - choose it for plush gravel and cyclocross.

Same-family: the dedicated gravel/CX 35mm - the 40mm gravel rim ($310) adds aero, the 30mm rim adds comfort.

Rated to a 105kg system weight.

Target Audience & Usage Notes.

Gravel racing, cyclocross, bikepacking and gran fondo.

Max system weight 105kg; not downhill or heavy trail.

Disc only (Center Lock or 6-bolt).

The Ride That Awaits.

Pin it into a cyclocross turn and feel the V-section shrug off the crosswind - steadier than a deep rim, wider than a race hoop, built for exposed gravel. The tubeless clincher beds wide tires cleanly and holds its line through long races. Pick your inner width and layup; a 3-year rim warranty has you covered.

Specifications
Size: 700c

Weight Tier: 330g-400g
Trade-offs & Considerations
Aero vs Crosswind: 35mm depth saves about 2.5W versus a 28mm rim at 40km/h; at 10° yaw the 30mm outer width stays composed — a calm middle ground between the 30mm and 45mm builds.
Weight vs Stiffness: The lightest 330g build saves about 70g versus the 400g top of the tier at the same 35mm depth (±5g); lateral stiffness holds within 3% across the range.
Tire-Type Trade-off: The hooked bead accepts clincher and tubeless tyres from about 33c to 50c (24mm internal for 33–42c, 25mm internal for 40–50c); tubeless cuts rolling resistance but needs tape, valve and sealant to seal the bed.
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 24–25mm inner rim, and what pressure suits me?
The 24mm inner width suits 33c–42c cyclocross tyres and the 25mm width suits 40c–50c gravel tyres; run them around 30–50 PSI by tyre width and your weight, on a hooked bed.
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 24–25mm 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.
