700C Carbon Road Rim 25mm wide 40/45mm wave | Bola

• Material: Toray carbon
• Rim depth: 40mm&45mm
• External width: 34mm(body)/31mm(edge)
• Internal width: 25mm
• Size: 700c
• Profile: Wave UV Profile
• Weight Tier: Standard (≈450g), Superlight (≈420g), Ultralight (≈395g), Extreme Light (≈375g)
• Max Tire Pressure: 90psi

• Aero vs Crosswind: 45mm depth maximizes aerodynamics for flat/time-trial efforts, while 40mm reduces crosswind sensitivity for mixed-terrain and endurance.
• Weight vs Durability: Extreme Light at ~375g saves up to 75g/rim vs Standard at ~450g, but impacts durability; Standard is recommended for riders over 100kg.
• Tire Volume vs Speed: 25mm inner width supports 28–32mm tires, improving comfort and rolling efficiency, but slightly less aero than narrower rims; ideal for endurance.
• Price vs Performance: Higher weight grades cost more, but provide reduced rotating mass for race day; choose based on budget and intended use.

• Fatigue Test: 750,000 cycles @640N (ISO 4210-7 Annex A, informative only)
• Impact Resistance: >40J (ISO 4210-7 reference)
• Flatness: <0.25mm (internal QC)
• Roundness: <0.3mm (internal QC)
• Max Spoke Tension: >300kg (internal QC)
• Ultimate Strength: >100kg (internal QC)
• Dynamic Equilibrium: <3g (internal QC)
• Radial Stiffness: 90–110 N/mm (internal lab)
• Lateral Stiffness: ≥8N/mm
• Max System Weight: 105kgs

• Climbing / Hill Repeats: Good (lighter weight options enhance climbing)
• Gran Fondo / Endurance: Excellent (designed for endurance with 40mm depth and wide tire compatibility)
• Road Racing: Excellent (aero profile and disc brake compatibility)
• Sprinting / Criterium: Good (stiff enough for sprints, but not the stiffest rim)
• Training / Daily Riding: Suitable (durable construction, but may be overkill for daily training)
• Not Recommended For: Off-road or gravel riding (road-specific geometry and brake type)

• Frame Compatibility: Disc brake road frames with 700c and clearance for 29-44mm tires
• Tire Type: Clincher or tubeless
• Tire Width Range: 28–32mm
• Brake Standard: Disc brake only
• Drivetrain: N/A (rim only)
• Rotor Standard: N/A (rim only)

What tire sizes are compatible with this rim?

This rim has a 25mm inner width, optimized for 28–32mm road tires. This wider profile increases air volume, reducing rolling resistance and improving comfort. It is not recommended for narrower tires below 28mm as the profile may not seat optimally. Always check manufacturer recommendations for tire/rim compatibility.

Can this rim be set up tubeless?

While not explicitly stated in the description, the 25mm inner width and modern design suggest tubeless compatibility. To run tubeless, you'll need rim tape, tubeless valves, and sealant. Ensure the tire and rim combination is rated for tubeless. If in doubt, consult the manufacturer or a professional mechanic.

What are the weight options and how do they affect performance?

The rim is available in four weight grades: Standard (~450g), Superlight (~420g), Ultralight (~395g), and Extreme Light (~375g). Lighter rims reduce rotating mass, improving acceleration and climbing. However, lighter rims may be less durable and are not recommended for heavier riders or rough roads. Choose based on your weight and intended use.

Can I customize the build of this rim?

Yes, the rim is custom-build ready. Valve and spoke hole diameters, nipple angles, and spoke patterns are customizable for OEM or team-specified builds. The rim is drilled for 24 spokes, but other configurations may be possible with custom drilling. Consult the manufacturer for detailed customization options.

How should I maintain and inspect this carbon rim?

Regularly inspect the rim for cracks, delamination, or impact damage after hard rides. Check spoke tension and true the wheel periodically. Clean with mild soap and water, avoid harsh chemicals. For carbon rims, avoid excessive heat from braking; since this is disc brake specific, that is less of a concern. Follow manufacturer guidelines for pressure and torque.
