Cerchio in carbonio gravel con profilo a onda, larghezze 34/25mm, opzioni di profondità 35/40mm, tubeless-ready e quattro fasce di peso da 370 a 440g.

Cerchio su misura per superfici miste

Il cerchio gravel BOLA da 34mm stabilizza i moderni pneumatici gravel da 29–44mm per una guida sicura su superfici sciolte o variabili. Scegli tra una profondità del profilo di 35mm o 40mm, con quattro gradi di stratificazione da 370g a 440g.

Guida all'acquisto.

Fascia di peso - Extreme Light ~370g: gravel competitiva ottimizzata nel peso.

Fascia di peso - Ultralight ~390g: gravel per le gare.

Fascia di peso - Superlight ~415g: endurance per tutto il giorno.

Fascia di peso - Standard ~440g: il montaggio più versatile per l'allenamento.

Profondità - scegli l'onda meno profonda per la stabilità con vento laterale su terreni aperti, o l'onda più profonda per una maggiore aerodinamica su sterrati veloci.

Montaggio - foratura leggera a basso carico: non adatto a sollecitazioni intense o grandi carichi da bikepacking.

Pubblico di riferimento e note sull'utilizzo.

Ciclisti gravel, bikepacker e ciclisti endurance su superfici miste.

Non adatto per downhill pesante o guida aggressiva a causa del numero di raggi di 24H.

La corsa che ti aspetta.

Mettiti sulla linea di partenza di una gara gravel e senti la sezione a onda mantenere la traiettoria sullo sterrato smosso, con l'ampio canale che supporta pneumatici da 29-44mm offrendo un grip che non molla mai. È abbastanza leggero per inseguire la fuga, abbastanza stabile per completarla. Una garanzia di 3 anni e la spedizione gratuita significano che devi solo metterci le gambe.

  • PSI massimo: 90
Translation missing: it.product.metafields.tradeoffs
  • Peso vs Durability: Lighter layups (Extreme Light 370g) sacrifice some impact resistance compared to Standard (440g) which provides more margin.
  • Aero vs Crosswind: 40mm Altezza offers more aero benefit on flats but is more crosswind-sensitive than 35mm.
  • Tire Volume vs Speed: 25mm internal width supports 28-50mm tires for more volume and traction, but narrower tires roll faster on smooth surfaces.
  • Price vs Grade: Higher-grade layups and custom options increase cost; Standard layup offers best value.

  • Gravel Racing: Excellent. Wide 25mm internal width supports up to 50mm tires for traction, and 35mm Altezza limits crosswind.
  • Bikepacking: Good. Wide tire clearance and sturdy build, but heavier layups may be preferred for durability.
  • Gran Fondo / Endurance: Suitable. 35mm Altezza and wide internal rim add comfort, but not as aero as deeper rims.
  • Road Racing: Not recommended. Designed for gravel, not optimal for road racing where aero and Peso are critical.
  • Training / Daily Riding: Suitable. Durable construction and Tubeless-ready design make it practical for everyday use.
  • Not Recommended For: Not for heavy downhill or aggressive riding due to lower Raggio count (24H).
Translation missing: it.product.metafields.compatibility
  • Frame Compatibility: Compatible with 700c disc Freno frames designed for gravel or road use.
  • Tire Type: Tubeless-ready clincher tires.
  • Tire Width Range: 29-44mm.
  • Freno Standard: Disc Freno only.
  • Drivetrain: Compatible with standard road/gravel drivetrains (not specified).
  • Rotore Standard: N/D (rim does not include Rotore).

What tire sizes are compatible with this rim?

The rim has a 25mm internal width and supports tires from 28mm to 50mm. It is designed for Tubeless setups, allowing lower pressures for better traction. For example, a 40mm gravel tire works well at 30-40 psi.

How does the rim Peso affect performance?

Peso ranges from 370g (Extreme Light) to 440g (Standard). Lighter rims reduce rotating mass, improving acceleration and climbing, but may be less impact-resistant. Choose based on your riding style and Peso.

Can I build this rim with any Mozzo?

Yes, it has 24 Raggio holes and standard 4.5mm Raggio holes. It is designed for disc brakes, so use a disc-specific Mozzo. The rim is compatible with both 6-bolt and centerlock hubs depending on your Raggio choice.

What is the maximum pressure for this rim?

The recommended tire pressure range is 100-125 psi, but for gravel use, much lower pressures (30-60 psi) are typical to increase traction and comfort.

How do I maintain the carbon rim?

Regularly inspect for impact damage, especially after rough rides. Clean with mild soap and water. Check Raggio tension periodically. Avoid Freno heat as it's disc-specific, so no Freno track issues.
