CONSPIT EX300 APEX Rim
Give your 310 APEX a compact endurance-style grip. The EX300 replacement rim uses a 300 mm format, flat-bottom shape and raised grip zones to change the feel of the steering interface around your existing APEX controls. Its three-point mounting structure is designed for the compatible 310 APEX assembly.
