ROLLCii RC29DB 6-BOLT 32HOLE REAR HUBS
One of the best things about custom wheelsets is being able to build something that truly matches your riding style. From rim depth and width to spoke count, riding purpose, and even color matching with your frameset, every detail can be tuned to create a wheelset that feels more personal and better balanced on the road or trail.
The ROLLCii RC29DB ISO 6 Bolt hubs are built around that same idea. Developed from the proven RC25DB platform, the RC29DB combines a finely machined hub body and axle structure with a clean, understated design that keeps weight low while maintaining good stiffness and long-term durability.
Designed around a strong machined 15mm steel axle, the hub is able to use larger bearings for improved durability and longer bearing life. The front hub is also designed with better versatility in mind, compatible with 100x15mm, 100x12mm, and quick release end caps for easier use across different bike setups.
Inside, high-quality sealed bearings help deliver a smooth and dependable ride feel through daily riding, gravel roads, wet weather, and longer adventures. The upgraded double-phase freehub system uses independent 6 pawls with 36 teeth, reducing engagement angle to 5 degrees for quicker pickup and a more direct pedaling feel without excessive noise or drag.
Designed for disc brake road bikes, gravel bikes, and modernized vintage 26” MTB builds, the RC29DB is a reliable option for riders who want a custom wheelset that feels smooth, durable, and easy to ride every day — whether heading out for a fast morning ride, weekend gravel route, or loaded bikepacking trip.
