Customisation Options Hole diameters (valve, spoke, assembly) available in custom sizes Nipple direction configurable per axle position Compatible with tubeless, clincher, and tubular setups OEM branding and colourway available for team and brand orders Frequently Asked Questions What rim depth is best for an Ironman bike build? For flat to moderately rolling Ironman courses, an 80mm deep rim offers a strong aerodynamic return. Most athletes and coaches target 60–90mm depth for time-trial and triathlon disciplines where sustained speed outweighs handling variability. Riders in consistently windy conditions may prefer 60–65mm for a better crosswind margin. Is the 34mm wide carbon rim better than 30mm for triathlon aerodynamics? The 34mm outer width pairs best with 25–28mm tyres, aligning the rim-to-tyre transition for reduced aerodynamic drag. The 30mm option suits 23–25mm tyres and saves approximately 30 g per rim. For most modern triathlon setups running 25mm+ tyres, the 34mm profile is the recommended choice. How heavy should a 700c carbon rim be for a triathlon wheelset? Competitive 80mm carbon rims typically weigh between 560 g and 650 g. At 580–610 g, this rim sits within the performance bracket, balancing aerodynamic depth with rotational mass suitable for Ironman and Olympic-distance racing. What does UV shape mean compared to a standard box-section rim? UV shape describes a toroidal (rounded) outer rim profile. Unlike a squared box-section, the curved surface improves airflow re-attachment at varied yaw angles, reducing aerodynamic drag in crosswind conditions common on open triathlon courses. Are these rims compatible with tubeless tyres? Yes. The 23mm inner width and 6.5mm valve hole are compatible with tubeless and tubeless-ready tyre systems. Confirm hook or hookless compatibility with your specific tyre brand before assembly.\",\n  \"brand\": {\n    \"@type\": \"Brand\",\n    \"name\": \"Carbon Fiber Sporting Goods\"\n  },\n
