Ritchey WCS Drop In Headset

The fully integrated Ritchey WCS Integrated Standard bottom bracket shell, IS47, for frames with a 47 mm bearing seat and forks with a 1 1/4 inch / 33 mm steerer tube diameter at the bottom

The WCS version of the Ritchey headset is fully equipped with high-quality industrial bearings. The well-sealed tapered precision bearing at the bottom and the compact precision bearing at the top are very easy to adjust and run with almost no resistance. Unlike press-fit headsets, the Drop In models do not have additional bearing cups but are inserted directly into the frame.

Ritchey WCS headset bearings:

the full-contact bearings with titanium-coated raceways, combined with high-quality, exceptionally smooth balls and water-repellent Ritchey Special grease, ensure highly durable bearings.

IS headset system:

The IS headsets are inserted into the head tube and require no additional bearing cups. The frame’s head tube also serves as the bearing cup for the headset

IS47/33 Headset Bottom Dimensions:

The bottom dimension is 47 mm and the headset taper on the fork is 33 mm, 1 1/4 inches.
