C-hub has large openings for quick & easy CVD and ECS assembly/disassembly. The entire CVD and ECS assembly can be easily inserted/removed through the C-hub without disassembly. The large openings prevent collision of CVD and ECS with C-hub in serious crashes, and are designed for use with optional ECS drive shafts.
The C-hubs are available in all standard caster angles (0, 2, 4 and 6) and are also available in 2 different hardnesses (Medium, Graphite) for different racing conditions.
