32.76 mm inner rim diameter
Same rim as the SH-II and 69C4, so moving between those pieces doesn't change what your lip sits on.

Independent shopping perspective
Gold-plated Helleberg-style tuba mouthpiece cut specifically for F tuba: shallower bowl cup, tighter throat, quick-opening backbore. For players who already know Helleberg dimensions suit them.

What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 01
Same rim as the SH-II and 69C4, so moving between those pieces doesn't change what your lip sits on.
Detail 02
Less cup volume than a full Helleberg, which keeps a small F tuba focused instead of spreading and going dull.
Detail 03
Tighter throat concentrates the air and adds core on a horn with less bore to fill.
Detail 04
Opens up quickly below the throat, so the tighter throat gives resistance to lean on without feeling stuffy.
Detail 05
Warmer and slightly grippier on the lip than silver, and the usual choice for players who react to silver or nickel.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Same rim. The SH-IIF has a shallower bowl cup, a smaller throat and a slightly larger, quicker-opening backbore, all scaled for the smaller F tuba.
You can, but it's cut for F. On a large horn the shallower cup and tighter throat leave you short on body. The SH-II fits that horn better.
Yes — it's built along the same lines as the 66, 67 and standard Helleberg, with Schilke's own rim contour and backbore work.
It's a feel and skin-tolerance choice, not a sound upgrade. Gold sits warmer and grippier on the lip; silver feels firmer and slicker.
