It may look like a $450 fillet brazed stem from a custom frame builder, but the Grand Cru Quill Stem is actually made using a custom one-piece steel quill and extension. The clamp is welded onto the extension and the weld is hand-filed smooth on top. This results in a strong yet relatively light stem with a classic shape.
There is a 5mm boss on the drive side for mounting a Temple Bell (sold separately in Brass and Mirror). Not compatible with the Striker Bell.
26.0 mm clamp.
