Salsa's Nickless cage holds bottles securely and the stainless steel construction won't mar your bottles like aluminium cages. Yep, it's a bottle cage. The 1/2" cutouts in the attachment plates make up a significant difference that sets these cages apart from other stainless offerings. Grab a couple of 1/2" width hose clamps from your local hardware store and you're set to strap these onto just about anything. Salsa may not recommend this mounting practice but it definitely works!
