Check this shank designation when selecting the 0AL.

Independent shopping perspective
The gold 0AL is a large-shank Heritage Series trombone mouthpiece aimed at strong, advanced players. Its 27.42mm cup, 6.09mm rim, 7.45mm bore, and barrel backbore distinguish the model, which is described as delivering clean, precise attacks in the low register. The Heritage layout adds mass around the throat and backbore while thinning the upper walls, intended to preserve sensitivity at softer levels and provide power through the dynamic range.
