700c Carbon Tubular Rim – 50mm Deep, 25mm Wide, 355g
This carbon tubular road rim combines a 50mm aerodynamic profile with a modern 25mm width and lightweight construction starting at 355g (Superlight). It is engineered for competitive road cycling and criterium racing where low rotational weight and high strength are priorities. Verified to withstand forward compressive strength >300kg and compatible with tire pressures up to 125 psi, it supports riders up to 100kg.

Frequently Asked Questions (FAQ)
Q: What makes a 50mm deep, 25mm wide tubular rim suitable for both flat and hilly races?A: The 50mm profile balances aerodynamic gains for flat courses with manageable weight for efficient climbing, while the 25mm width optimizes tire shape for stable cornering and reduced rolling resistance.
Q: How does a carbon tubular rim compare to a clincher rim for professional cycling?
A: Tubular rims provide lower rotational weight and superior ride feel for race conditions but require more skill for tire installation and repair compared to clincher or tubeless-ready clinchers.
Q: Are 25mm wide carbon tubular rims better than 23mm?
A: 25mm width improves aerodynamic transition with modern 25–28mm tires, offering increased stability and comfort while maintaining low drag compared to narrower rims.
Q: What warranty and certifications does this rim offer?
A: 3-year manufacturer's warranty covering structural defects. Manufactured using industry-standard carbon fiber quality controls; custom hole sizes available for OEM needs.
