The Bola 700C 35mm U-shape carbon tubeless rim - a 28mm-wide hooked disc-brake aero rim for climbing, all-round road and endurance builds.

Race-ready depth with practical everyday performance: the Bola 35mm U-shape rim balances aero benefit and ride compliance for road training, racing and mixed-surface riding. Thirty-five millimetres of carbon, 28mm wide, sold rim-only.

Buying Guide.

Weight tier - Extreme Light ~330g: the climber's pick - lightest end for training, racing and mixed surfaces.

Weight tier - Ultralight ~350g: the balanced middle - lively on climbs, tough enough to train.

Weight tier - Superlight ~370g: the steady build - impact margin for windy training days.

Weight tier - Standard ~415g: the durable daily choice that shrugs off year-round miles.

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

Same-depth series: the 35mm asymmetric balances disc spoke tension; the 35mm tubular is the glued race option.

Adjacent depth: the 30mm U-shape is shallower; the 40mm U-shape adds aero.

Target Audience & Usage Notes.

Target audience.: Climbers, endurance riders and those in windy terrain.

Rim-only.

Hooked bed supports up to 125 psi; respect 105kg.

Not for off-road/gravel over 32mm.

The Ride That Awaits.

Build it around a disc road hub, seat a 28-32c tubeless, and the 35mm U-profile settles in: fast enough for training, light enough for climbing, as steady in the wind as an old friend. The year-round wheelset that asks nothing of you. Free shipping, a 3-year rim warranty and crash-replacement discount.

Weight Tier: Standard 415g, Super Light 370g, Ultra Light 350g, Extreme Light 330g
Trade-offs & Considerations
Aero vs Crosswind: The 35mm depth sits between a climbing and an aero rim: it saves about 1.5W versus a 30mm rim at 40km/h, and at 10° yaw the 28mm outer width keeps steering calm, trading a little raw aero for easy handling.
Weight vs Stiffness: The Extreme Light tier (330g) saves 85g versus the Standard tier (415g) (±5g); lateral stiffness holds within 3% across tiers on the same 35mm lay-up.
Tire-Type Trade-off: The hooked 21mm inner width runs 25–32mm clincher or tubeless road tyres; the bed is factory-sealed, so tubeless needs only a valve and sealant, cutting rolling resistance and pinch flats.
Sourcing & Delivery Trade-off: Stock drilling ships in 1–3 business days at $310; custom valve, spoke or assembly hole diameters and decals add 7–15 business days and roughly a $40–80 premium.

Recommended Use Cases
Climbing / Hill Repeats: Good. Weight options down to 330g make it competitive on climbs.
Gran Fondo / Endurance: Excellent. 35mm depth and 28mm outer width provide aero efficiency and compliance for long rides.
Road Racing: Excellent. Aero profile and stiffness support aggressive riding.
Sprinting / Criterium: Suitable. 35mm depth is responsive, though deeper rims may offer more aero at high speeds.
Training / Daily Riding: Excellent. Durable Standard weight (415g) withstands daily use.
Not Recommended For: Not recommended for off-road/gravel with tires over 32mm or technical terrain.
Compatibility
Frame Compatibility: Road frames with 700c wheels and disc brake mounts (flat mount or post mount depending on build).
Tire Type: Clincher or tubeless (non-hookless) tires.
Tire Width Range: 25-40mm (optimal 28-32mm)
Brake Standard: Disc (center-lock or 6-bolt)
Drivetrain: Compatible with standard road hubs (Shimano/SRAM/Campagnolo) depending on hub choice.
Rotor Standard: Center-lock or 6-bolt

FAQ
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 is the maximum spoke tension for 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.
What tyres can I mount on this rim, and what pressure should I run?
The 21mm hooked inner width is compatible with standard clincher and tubeless tyres from 25mm to 32mm, with 28–32mm the sweet spot.
Is this sold as a complete wheelset, or as a bare rim I build myself?
This is a bare rim only — no hub, spokes, nipples or tape included. You choose the hub and spokes and build it to your spec, or use it as a direct replacement for a damaged rim.
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.
