The Bola 700C 35mm asymmetric metric carbon tubular rim - a light offset-bed 28mm-wide glued-tyre rim for stiff, true climbing wheels.

The stiff, true, featherweight: the Bola 35mm asymmetric metric tubular offsets the spoke bed for balanced tension and a metric drill option. Thirty-five millimetres of T700/T800 carbon, 28mm wide, sold rim-only.

Buying Guide.

Weight tier - Superlight ~300g: the stiff-featherweight pick - lightest end with the offset metric drill for a true, planted rear wheel.

Weight tier - Normal ~325g: the durable choice - a touch more layup margin for rough mountain roads.

Max rider weight: rated to 105kg - check rider + gear before ordering.

Same-depth series: the 35mm tubular is the symmetric version; the 35mm U-shape tubeless is the tubeless road version.

Adjacent depth: the 40mm tubular asymmetric adds aero; the 30mm asymmetric tubeless is shallower.

Target Audience & Usage Notes.

Target audience.: Climbers who want a stiff, true rear wheel on tubulars.

Rim-only.

Glue your own tyres; use carbon-specific rim-brake pads; respect 110 psi and 105kg.

Not for riders unwilling to glue.

The Ride That Awaits.

Cement a 25-28mm tubular, lace to a climbing hub, and the metric offset builds a stiffer, truer rear wheel: 300g of rim, 35mm of modest aero, the glued tyre lending its voice through every bend. Light, planted, ready to carry you. Free shipping, a 3-year rim warranty and crash-replacement discount.

Specifications

Size: 700c

Material: Genius Toray carbon fiber

Rim Depth: 35mm

Rim Type: Tubular / Glue-on

Glue Bed Width: 28

ERD (Effective Rim Diameter): 569

Weight Tier: Superlight 300g / Normal 325g (+/-15g)

Trade-offs & Considerations

Aero vs Crosswind: 35mm depth saves about 1.5W versus a 28mm rim at 40km/h; at 10° yaw this is the calmest depth of the tubular family, trading outright aero for easy handling on climbs and rolling roads.

Weight vs Stiffness: The Superlight layup (300g) saves about 25g versus the Normal layup (325g) at the same 35mm depth (±5g); the asymmetric spoke bed equalises left/right spoke tension for a stiffer, truer rear wheel, and lateral stiffness holds within 3%.

Tire-Type Trade-off: Glue-on tubulars give about 8% lower rolling resistance than clincher tubeless, but the tyre is glued: service every 3–6 months, no roadside puncture repair and no sealant-based flat prevention.

Sourcing & Delivery Trade-off: Stock drilling ships in 1–3 business days at $310; custom spoke-hole count or valve hole adds 7–15 business days and roughly a $40–80 premium.

Recommended Use Cases

Road Racing Builds: 2026 peloton standard is 28-30mm tubeless on wide rims (TdF 2026 avg ≈30mm); 35mm section suits 40+ km/h racing.

Gran Fondo / Endurance: Modern 2026 frames (Propel, SuperSix, S5) design around 30-32mm clearance; 21mm inner bed pairs 25-32mm tubeless per ETRTO 2026 guidance.

Wheel Building: Custom road builds with disc or rim hubs; UD carbon layup options for weight-conscious or durable builds.

Weight Tier Selection: Offered in weight tiers (105kg); lighter for climbing, heavier for training and impact margin.

Compatibility

Frame: 700C (ISO 622) road frames with rim brakes

Tire Type: Tubular (glued)

Tire Width: 25-32mm tubular

Valve: Presta (tubular valve)

Brake: Rim brake - use carbon-specific pads

FAQ

Do I get a bare rim here, or is it built up with a hub and spokes?

It's a bare carbon rim — no hub, spokes or nipples. Take it to any wheel builder to lace it to your own hub; we can also supply a built wheel on request.

Can I run clincher or tubeless tyres on this, or is it a glue-on tubular rim?

This is a dedicated tubular rim: you glue on tubular tyres. It is not drilled or shaped for clincher or tubeless clincher tyres.

What spoke drillings are available, and which brake type is this rim rated for?

Spoke drillings and brake rating depend on the build option, selectable at checkout. If you plan to lace your own wheel, confirm the drilling and brake type with Bola before ordering so the rim matches your hub and frame.

What spoke tension can I safely build to — will the holes pull out of the carbon?

Drive-side / disc-side maximum tension is 130–140 kgf, with the non-drive side adapted to match; the spoke holes are locally reinforced inside the carbon layup to prevent pull-out cracking.

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, and delivered to your door with no extra payment to customs or the courier.
