The Bola 700C 90/95mm wave carbon rim - a deep 90/95mm wavy TT/triathlon rim, 28mm outer / 21mm internal, ~615g, hooked tubeless, for rear-wheel aero builds.
When the wind is the only opponent and the course runs straight, the wavy 90/95mm rim answers with calm defiance of drag.
Buying Guide.
Use case: a rear-wheel specialist for flat TT and triathlon, where deep-section aero matters more than light weight.
Course judgement: the wavy shape tames crosswinds better than a flat 90mm rim, but it is still a flat-course tool, not a climbing or road-race rim.
Tyre choice: run 25-32mm race rubber on the narrow internal bed for high-pressure, low-drag rolling.
Same-depth series: the 180mm aero rim ($450) goes deeper for maximum flat speed; the 120mm aero rim ($420) is shallower and calmer.
Adjacent depth: the 88mm hooked tubeless rim ($350) is the classic deep spoked option at a similar price.
Use as a rear wheel; respect the system weight limit.
Target Audience & Usage Notes.
TT/triathlon rear-wheel builds and wheel builders.
Rear-only on flat courses; disc-brake frames (verify). 25-32mm tubeless/clincher tyres, 100-125 PSI. 125kg rider limit.
Not for climbs, road races or crosswind-heavy courses.
The Ride That Awaits.
Built as a rear wheel, it holds an effortless, momentum-longing line; the wavy rim cuts a calm, purposeful shape through the fastest road you can find.
You sit low and stay gone.
Free shipping and a 3-year rim warranty support your aero build.

Translation missing: en.product.metafields.tradeoffs
- Aero vs Crosswind: Deep 90/95mm profile offers excellent aerodynamic efficiency but can be challenging in strong crosswinds; wave design mitigates but not fully. The 28mm external width helps stability, but crosswinds above 30km/h require attention.
- Weight vs Durability: At 615g±15g, it is light for its depth, but the high-modulus carbon is less forgiving on impacts than alloy. Prioritizes stiffness and aero over impact toughness, so avoiding potholes is advised.
- Tire Volume vs Speed: 21mm internal width supports 25-32mm tires; wider tires (28-32mm) improve comfort and grip but may have higher rolling resistance than 25mm. Optimal 28mm balances speed and comfort on varied surfaces.
- Price vs Performance: Premium high-modulus carbon and tubeless-ready construction command a higher price, but the aero gains and weight savings justify it for competitive TT and triathlon use.

Translation missing: en.product.metafields.usecases
- Sprinting / Criterium: Good. The deep rim provides aero benefits on fast, flat circuits, but the 615g weight and crosswind sensitivity make it less nimble in tight corners.
- Triathlon / TT: Excellent. Designed for time trials and triathlons, the 90/95mm depth and tubeless compatibility offer maximum aero efficiency and speed.
- Road Racing: Good. Suitable for flat to rolling races where aero gains outweigh weight penalty; not ideal for hilly routes.
- Gran Fondo / Endurance: Suitable. The 28mm external width and ability to run 28mm tires provide comfort, but crosswind handling may be tiring on long rides.
- Climbing / Hill Repeats: Not recommended. The 615g rim and deep profile are heavy and less efficient on steep grades.
- Not Recommended For: Technical descents, heavy crosswinds, and steep climbs.
Translation missing: en.product.metafields.compatibility
- Frame Compatibility: 700C (ISO 622) - fits most road, TT, and triathlon frames with appropriate clearance
- Tire Type: Tubeless ready (hooked bead) and clincher
- Tire Width Range: 25-32mm (optimal 28mm)
- Brake Standard: Disc brake (centerlock or 6-bolt)
- Drivetrain: Compatible with Shimano, SRAM, and Campagnolo via correct freehub body
- Rotor Standard: Disc brake rotor (centerlock or 6-bolt)

Is this rim tubeless-ready?
Yes, it features a hooked tubeless bead (ETRTO standard) and is designed for tubeless tires. It supports pressures between 100-125 psi, ensuring a secure and airtight seal. The hooked bead reduces the risk of tire burping during high-pressure efforts.
What tire widths can I use with this rim?
The 21mm internal width accommodates tires from 25mm to 32mm. The optimal width is 28mm, which balances rolling resistance, grip, and comfort. It is also compatible with clincher tires, offering versatility.
How much weight can I save compared to a standard alloy rim?
This carbon rim weighs approximately 615g±15g, which is significantly lighter than a typical alloy aero rim of similar depth (often 800g+). This weight saving contributes to lower rotational mass and faster acceleration.
Can I build a custom wheelset with this rim?
Absolutely. This rim is designed for custom builds. You can pair it with your choice of hubs and spokes. It supports spoke tensions above 300kg, so it is compatible with high-quality hubs and spokes for a durable and stiff wheelset.
How do I maintain and inspect this rim?
Regularly inspect the rim for cracks, delamination, or impact damage, especially after hard rides. Check spoke tension and true the wheel as needed. Avoid excessive brake heat if using rim brakes (this is a disc-brake rim). Store in a cool, dry place and use carbon-safe cleaning products.
