The 25mm internal width of this rim comfortably accommodates gravel tires up to 45mm wide, making it well-suited for gravel endurance and mixed-surface racing. The wider internal channel improves tire casing support and reduces pinch flat risk compared to rims under 21mm internal width.\u003c\/p\u003e\n\u003ch3\u003eHow much weight can I save by choosing the extreme light (385g) grade over standard (460g)?\u003c\/h3\u003e\n\u003cp\u003eSwitching from the 460g standard to the 385g extreme light grade saves 75g per rim, or approximately 150g per wheelset. At typical road build weights, this is a measurable reduction. However, the extreme light layup has a tighter structural margin; it is best suited for riders under 75 kg on road-only surfaces.\u003c\/p\u003e\n\u003ch3\u003eWhat is the difference between 45mm and 50mm depth for climbing vs flat roads?\u003c\/h3\u003e\n\u003cp\u003eThe 45mm depth offers a lower aerodynamic drag penalty in crosswinds and a marginally lower rim weight, making it the preferred choice for climbing and technical courses. The 50mm depth provides greater aerodynamic advantage on flat or rolling terrain above approximately 38 km\/h. For a general-purpose disc brake build, the 45mm depth is the more versatile option.\u003c\/p\u003e\n\u003ch3\u003eWhat should I look for in a wide carbon rim for a tubeless disc brake setup?\u003c\/h3\u003e\n\u003cp\u003eKey parameters include: internal width ≥23mm for road tubeless or ≥25mm for gravel tubeless, a hooked or hookless bead seat profile, flatness tolerance ≤0.2mm for reliable tubeless seating, and a valve hole diameter compatible with your valve stem (6.5mm accommodates most standard road valves).

Yes. The 23mm inner width and U\/UV rim shape are tubeless-ready when used with appropriate rim tape (recommend 25mm width) and tubeless valve stems with a 6.5mm hole diameter. Maximum tire pressure is 125 psi. What is the difference between the superlight and ultralight grades? The superlight grade (400 ±10g) uses a balanced carbon layup suitable for most competitive road and endurance applications. The ultralight grade (380 ±10g) reduces weight by approximately 20g per rim through a refined layup schedule. Both pass the same structural tests; however, the ultralight grade is recommended for riders under 85 kg on smooth road surfaces. Is a 34mm wide rim better than 30mm for road aerodynamics? For tires 28mm and wider, the 34mm outer width reduces the tire-rim shoulder gap, which wind tunnel data from rim manufacturers consistently shows improves aerodynamic efficiency above 35 km\/h. For 25mm tires, the 30mm outer width maintains a better aerodynamic profile ratio. What tire pressure should I use with these rims? The rated range is 100–125 psi. For tubeless setups with 28mm tires, most riders perform well at 70–90 psi, though the structural rating remains 100 psi minimum for clincher use.

Tested up to 120 kg per rim, this model suits most adult riders for triathlon, road and TT builds. For heavier use, please consult Bola about custom layups. How does a 34mm wide rim affect aerodynamics in triathlon compared to 30mm or 25mm? Wider 34mm UV rims improve aerodynamic stability and airflow reattachment at typical yaw angles, helping maintain speed in crosswinds versus narrower rims (25–30mm) used in older models. Is the Bola 80mm rim compatible with both tubeless and clincher tires? Yes, it supports modern 25–28mm tubeless and traditional clincher tires for easy setup and reliable sealing performance. What is the difference between UV (toroidal) and standard U-shape rims for racing? UV (toroidal) profiles further reduce drag by managing airflow across varying wind angles.

The 23mm inner width and U\/UV rim shape are tubeless-ready when used with appropriate rim tape (recommend 25mm width) and tubeless valve stems with a 6.5mm hole diameter. Maximum tire pressure is 125 psi.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eWhat is the difference between the superlight and ultralight grades?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eThe superlight grade (400 ±10g) uses a balanced carbon layup suitable for most competitive road and endurance applications. The ultralight grade (380 ±10g) reduces weight by approximately 20g per rim through a refined layup schedule. Both pass the same structural tests; however, the ultralight grade is recommended for riders under 85 kg on smooth road surfaces.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eIs a 34mm wide rim better than 30mm for road aerodynamics?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eFor tires 28mm and wider, the 34mm outer width reduces the tire-rim shoulder gap, which wind tunnel data from rim manufacturers consistently shows improves aerodynamic efficiency above 35 km\/h. For 25mm tires, the 30mm outer width maintains a better aerodynamic profile ratio.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eWhat tire pressure should I use with these rims?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eThe rated range is 100–125 psi. For tubeless setups with 28mm tires, most riders perform well at 70–90 psi, though the structural rating remains 100 psi minimum for clincher use. Always verify with your tire manufacturer's pressure guidelines.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eCan I order custom spoke hole counts or private-label branding?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eYes. Spoke hole count, hole diameters, nipple angles, and OEM\/private-label branding are all available as custom configurations.

The 23mm inner width and U\/UV rim shape are tubeless-ready when used with appropriate rim tape (recommend 25mm width) and tubeless valve stems with a 6.5mm hole diameter. Maximum tire pressure is 125 psi.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eWhat is the difference between the superlight and ultralight grades?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eThe superlight grade (400 ±10g) uses a balanced carbon layup suitable for most competitive road and endurance applications. The ultralight grade (380 ±10g) reduces weight by approximately 20g per rim through a refined layup schedule. Both pass the same structural tests; however, the ultralight grade is recommended for riders under 85 kg on smooth road surfaces.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eIs a 34mm wide rim better than 30mm for road aerodynamics?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eFor tires 28mm and wider, the 34mm outer width reduces the tire-rim shoulder gap, which wind tunnel data from rim manufacturers consistently shows improves aerodynamic efficiency above 35 km\/h. For 25mm tires, the 30mm outer width maintains a better aerodynamic profile ratio.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eWhat tire pressure should I use with these rims?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eThe rated range is 100–125 psi. For tubeless setups with 28mm tires, most riders perform well at 70–90 psi, though the structural rating remains 100 psi minimum for clincher use. Always verify with your tire manufacturer's pressure guidelines.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eCan I order custom spoke hole counts or private-label branding?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eYes. Spoke hole count, hole diameters, nipple angles, and OEM\/private-label branding are all available as custom configurations.
