Wolf Tooth Headset Lower

This headset is designed for frames with a 49mm head tube inner diameter. You should verify your frame's specific headset standard—look for 'EC49' in your bike's technical specifications or measure the inner diameter of the lower head tube to ensure a precise fit.

Stainless steel bearings offer superior corrosion resistance compared to standard steel, making them ideal for riders who frequently encounter wet, muddy, or salty conditions. They help prevent the seizing and roughness that often develop in lower headsets due to their proximity to the front wheel's spray.

Yes, this Wolf Tooth lower headset assembly includes the necessary crown race. It is designed to fit a 40mm crown race diameter, which is standard for most tapered steerer tubes.

Yes, the external cup design is compatible with both frame materials, provided your frame utilizes the EC49 standard. However, always ensure your frame's head tube is clean and free of debris before pressing the cup to prevent damage to the frame interface.

While the cartridge bearings are high-quality and durable, they are replaceable. If the bearings eventually wear out, you can source replacement bearings that match the Wolf Tooth specifications without needing to press out and replace the entire external cup.
