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
How It Compares
FAQ
What is the tubeless setup?
The bed is factory-sealed: fit a tubeless valve, mount a compatible tyre and add sealant, then inflate with a high-volume pump to seat the bead.
Which tyres fit the hooked 21mm inner width?
Standard clincher and tubeless tyres from 25mm to 32mm, with the sweet spot at 28–32mm; avoid hookless-only tyres.
How much do the lighter tiers save?
Extreme Light (330g) saves about 85g per rim versus Standard (415g), improving climbing at a small durability cost.
Can I customise it for my hub?
Yes: valve hole (6.5mm), spoke hole (4.5mm), assembly holes (7.5mm) and nipple angles are configurable on request.
Which brake type is this rim for?
Disc brake builds only: keep the rim bed clean and rotors properly aligned.
