• Materiale: Carbon
• Altezza: 50mm
• Larghezza esterna: 30-34mm
• Larghezza interna: 23mm
• Misura: 700c
• Profile: Aero
• Peso Tier: Standard, Superlight, Ultralight
• PSI massimo: 90

• Aero vs Climbing: The 50mm Altezza provides significant aerodynamic benefit at speed, but adds Peso and crosswind sensitivity compared to shallower rims. Lightweight grades (Superlight, Ultralight) mitigate some Peso penalty, making it a versatile choice for rolling terrain.
• Stiffness vs Compliance: The 23mm inner width and deep profile increase lateral stiffness for precise handling, but the 50mm Altezza and Senza uncino design may transmit more road vibration. Using wider tires at lower pressures (e.g., 28mm at 60-70psi) can enhance comfort without sacrificing much aero.
• Tire Volume vs Speed: The 23mm inner width supports tires up to 32mm, improving grip and comfort, but wider tires increase drag. The rim is optimized for 25-28mm tires to balance speed and volume; 28mm is a sweet spot.
• Peso vs Durability: Standard grade offers robustness with slightly higher Peso; Superlight and Ultralight reduce Peso by using higher modulus fibers, but may be more prone to impact damage. The rim's structural tests (flatness <0.15mm, roundness <0.3mm) indicate quality, but lighter builds should be ridden carefully.

• 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 Raggio 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 Peso: 120kgs

• Sprinting / Criterium: Excellent. The 50mm Altezza provides aerodynamic efficiency for high-speed sprints and short bursts.
• Triathlon / TT: Excellent. Aero profile reduces drag at sustained speeds.
• Road Racing: Good. Versatile enough for most road races, especially with the lighter Peso grade.
• Gran Fondo / Endurance: Suitable. Deep section may feel heavy on long climbs, but Tubeless wider tires add comfort.
• Climbing / Hill Repeats: Not recommended. 50mm Altezza adds Peso and crosswind sensitivity; consider a shallower rim for pure climbing.
• Not Recommended For: Technical descents in strong crosswinds may be challenging; also not ideal for rough gravel.

• Frame Compatibility: Compatible with road frames designed for disc brakes. Ensure Mozzo axle spacing matches frame (typically 12x100 front, 12x142 rear).
• Tire Type: Tubeless-compatible, clincher (Senza uncino)
• Tire Width Range: 27-40mm
• Freno Standard: Disc Freno only (no rim Freno surface)
• Drivetrain: Compatible with standard road groupsets (Shimano, SRAM, Campagnolo) via Corpo mozzo choice
• Rotore Standard: Compatible with disc Freno rotors (mount type per Mozzo, e.g., center lock or 6-bolt)

What tubeless setup is required for this rim?

For tubeless setup, use tubeless-compatible rim tape and 6.5mm valves (the rim has a 6.5mm valve hole). The rim is hookless-compatible, so you'll need tires specifically rated for hookless rims. Recommended pressure for tubeless is typically lower than clincher; follow tire manufacturer guidelines. The rim is rated up to 125 psi for clincher, but tubeless setups often run 60-80 psi depending on tire width and rider weight.

What tire widths are compatible with this rim?

The rim has a 23mm inner width, supporting tire widths from 25mm to 32mm. Wider tires (28-32mm) provide more comfort and grip, while 25-28mm are more aerodynamic. Ensure the tire is compatible with hookless rims and verify that the tire's recommended pressure range aligns with the rim's max of 125 psi. The ERD is 538mm, which is standard for 700c rims.

How does rim weight vary across the different grades?

Bola offers three weight grades: Standard, Superlight, and Ultralight. Standard rims are heavier and more durable, typically around 520g. Superlight rims use higher modulus fibers to save about 30g per rim, dropping to ~490g. Ultralight rims further reduce weight to ~460g but may sacrifice some impact resistance. Exact weights can be requested from Bola for specific configurations.

Can I customize spoke hole count and drilling for my build?

Yes, the rim is OEM-ready and highly customizable. You can specify spoke hole count, hole diameters, and nipple angles (front 7°, rear 5° or 7°). This allows you to match your hubs and spokes precisely. The rim also supports private labeling and custom branding for teams and bicycle brands.

What maintenance should I perform to ensure rim longevity?

Regularly inspect the rim for cracks, delamination, or impact damage, especially after rides. Use a torque wrench to maintain even spoke tension, as uneven tension can lead to rim failure. Clean with mild soap and water, avoiding harsh chemicals. The rim has a 3-year warranty, but proper maintenance ensures it lasts. Also, stay within the recommended tire pressure and rider weight limit (120 kg) to avoid overloading.
