18 mm is standard-narrow bridge territory. Woolet signature bridges are 25 mm (009) and 26 mm (007 keyhole), built for wider noses. If 18 mm is genuinely your fit, mainstream retail is the honest answer.
We don't build at 18 mm. Signature runs 26 mm keyhole (007) and 25 mm (009); bespoke starts at 20 mm.
18 mm bridges are the mainstream default — designed for average-width noses on 140–148 mm frames. Woolet is built for wider faces (155 mm+), which usually come with a wider nose. We don't build 18 mm because a narrow bridge on a wide front pinches and slides.
Signature bridges: 26 mm keyhole (007) · 25 mm (009). Bespoke 20–26 mm.
