700C Carbon Clincher Road Rim, 50mm Depth, 25mm Outer Width, 18mm Inner, U-Shape — Bola

Reach higher speeds on long straights and feel composed in crosswinds with a rim built for aerodynamic efficiency and predictable handling. This 700C full carbon clincher rim balances a deep 50mm profile with a 25mm outer width to suit modern road tire setups while keeping weight options for performance-focused builds.

700C Carbon Clincher Road Rim — Designed for aerodynamic road riding

The U-shaped 50mm profile was engineered to reduce drag while offering stable steering feedback when conditions get windy. With an 18mm internal width matched to 25–32mm tires, the rim supports modern race and fast-club-ride setups where low rolling resistance and precise tire support matter.

Why it fits your routine

• Aerodynamic advantage: 50mm rim depth and U-shape profile optimize airflow for improved speed on flats and time-trial efforts.
• Modern tire compatibility: 25mm outer width and 18mm inner width accommodate 25–32mm clincher road tires to improve tire support versus older narrow rims.
• Lightweight options: Multiple weight variants (standard, super, ultra, extremelight) let builders prioritize stiffness or minimum rotating mass for racing or team wheelsets.
• Durable tolerances: Manufactured to tight dimensional tolerances (flatness <0.15mm, roundness <0.3mm) for consistent wheel builds and predictable truing behavior.
• Performance-tested: ISO lab-tested metrics include forward compressive strength >300 kg, lateral torsion >50 kg, and spoke hole tension >280 kg for reliable spoke retention under load.
• Ride limit and pressure: Rated for riders up to 100 kg and compatible with maximum tire pressures up to 125 psi, matching common road racing requirements.
• Wheelbuilding-ready: 6.5mm Presta valve hole and 558mm ERD provide straightforward lacing calculations and compatibility with typical road hubs.
• Consistent dynamic balance: Dynamic equilibrium <3g supports smoother high-speed performance and reduces vibration-related rim wear.
• Tradeoffs explained: Clincher-only construction simplifies tire installation and suits racing tire choices, while tubeless setups are not supported by this rim.

Key specifications include 700C rim diameter, U-shaped 50mm profile, 25mm outer width, 18mm inner width, ERD 558mm, Presta valve hole 6.5mm, and weight variants with typical values shown in product literature. The rim fits 700C road frames and is optimized for competitive road cycling and team wheel builds. Warranty coverage extends three years for manufacturing defects and excludes crash damage or overload beyond the stated rider weight limit.
