Logic Threadless Headset

An External Cup headset features bearing cups mounted outside the frame's head tube, making it easier to replace bearings when needed. This design provides a more stable connection between the fork and the frame, enhancing your bike's overall handling and performance. If you value ease of maintenance and stability, an External Cup headset is a great choice.

The EC34 designation indicates specific measurements: 34mm for the head tube diameter and either 28.6mm or 30mm for the bearing size. To ensure compatibility, measure your bike's head tube and check the specifications of your current headset. If they match, the EC34 will fit perfectly.

The Crown Race is a crucial component that sits at the top of the fork's steerer tube. It holds the bearings in place and allows the fork to rotate smoothly. A properly installed Crown Race ensures that your bike steers accurately and responsively, which is essential for a safe and enjoyable ride.

The Star Nut is a small, star-shaped piece that secures the top cap and adjusts the tension on the headset bearings. It keeps everything in place, ensuring that your headset functions correctly. A well-installed Star Nut contributes to smoother steering and better overall bike performance.

Bearing Cups are the components that hold the bearings in place within the headset. They provide a surface for the bearings to roll against, allowing for smooth steering. The design and material of the Bearing Cups can significantly impact the headset's performance and durability, so choosing high-quality cups can enhance your riding experience.

Yes, you can upgrade to an External Cup headset, but you'll need to ensure that your bike's frame is compatible with this design. Check the head tube diameter and the specifications of your current headset. If you're unsure, consult with a bike mechanic or specialist to help you choose the right upgrade for your bike.
