A hooked-wave disc-brake carbon rim with 34/31mm outer, 25mm inner width, 45/50mm depth options, and four weight tiers 385–460g.
Do-It-All Disc-Road Rim
The BOLA 34mm wide carbon rim balances low weight, predictable handling and tubeless compatibility. Choose 45mm depth for crosswind stability or 50mm for improved aero, with four weight grades to tune rotational mass.
Buying Guide.
Weight tier - Extreme Light ~385g: lightest, for smooth roads.
Weight tier - Ultralight ~405g: race builds.
Weight tier - Superlight ~425g: balanced all-round.
Weight tier - Standard ~460g: larger riders and rough roads.
Depth - choose the shallower wave for crosswind stability, the deeper wave for flat-course aero.
Internal width - 25mm: covers 29-44mm tires; a do-it-all bed between road and light gravel.
Target Audience & Usage Notes.
Road, gravel and endurance disc-brake riders.
Not for heavy downhill or extreme off-road; riders over 120kg should avoid lighter grades.
The Ride That Awaits.
Point it at a mixed-surface century and feel the hooked-wave bed balance aero and comfort in the same breath - 29-44mm tires at low pressure, the offset wheel true and calm under every effort. It is the do-it-all that never complains. Free shipping and a 3-year warranty mean you can plan the ride and trust the wheel.
Specifications
Size: 700c
Material: Genius Toray carbon fiber
Rim Depth: 45mm/50mm
Bead Type: Hooked
Inner Width: 25mm

ERD (Effective Rim Diameter): TBD
Weight Tier: Standard 460g, Superlight 425g, Ultralight 405g, Extreme Light 385g
Trade-offs & Considerations
Aero vs Crosswind: The 50mm wave profile saves about 4.5W versus a 35mm rim at 40km/h; at 10° yaw the 34mm outer width keeps steering predictable on exposed descents, at the cost of a higher crosswind signature than a 40mm rim. The 45mm drill option trades about 1W of aero for calmer side-wind handling.
Weight vs Stiffness: The Extreme Light tier (385g) saves about 75g versus the Standard tier (460g) at the same 50mm depth (±5g); lateral stiffness holds within 3% across tiers, so the lightest build keeps the same rim structure.
Tire-Type Trade-off: The hooked bead accepts clincher and tubeless tyres from about 28c to 50c and supports higher pressure than hookless designs; 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.

Recommended Use Cases
Gravel Racing: Excellent. Designed for mixed-surface racing with wide tire support and tubeless compatibility.
Bikepacking: Good. The wide internal width and durable construction handle loaded touring, though lighter weight grades offer less structural margin for heavy loads.
Gran Fondo / Endurance: Excellent. 25mm internal width and compliant ride make it ideal for long distances.
Road Racing: Good. 45-50mm depth provides aero benefits while still being manageable in crosswinds.
Training / Daily Riding: Excellent. Tubeless setup reduces flats, and multiple weight grades allow tuning for durability.
Not Recommended For: Heavy downhill or extreme off-road use; riders over 120kg should avoid lighter grades.
Compatibility
Frame Compatibility: Disc brake road/gravel frames with 700c wheels (ISO 622)
Tire Type: Tubeless and clincher
Tire Width Range: 29-44mm
Brake Standard: Disc brake only
Drivetrain: All drivetrains (Shimano, SRAM, Campagnolo) - hub dependent
Rotor Standard: Hub-dependent (Center Lock or 6-bolt)

FAQ
What tyre widths fit this rim?
With a 25mm internal width, run 28c to 50c clincher or tubeless tyres; the sweet spot is 28–32c on road and 35–45c on gravel.
How do I set it up tubeless?
Use the hooked bead seat with a tubeless valve and sealant; inflate with a compressor to seat the bead, then check with soapy water. Disc-brake builds need no brake heat considerations.
Which weight tiers are available?
Standard (460g), Superlight (425g), Ultralight (405g) and Extreme Light (385g) are selectable; the Extreme Light build suits riders under about 75kg on smooth roads.
Which brake type is compatible?
Disc brake builds only — this rim has no rim-brake braking surface.
Can I customize the drilling?
Yes: spoke-hole count, valve hole and nipple angles are adjustable for OEM or team orders; lead times add 7–15 business days.
