Made with scraps from the cutout inside Surly's stainless steel chainrings, this tool is an 18mm wrench to adjust Surly Singleator spring tension and a bottle opener.

• Polished, 2mm thick stainless steel with a laser etched Surly logo
• 18mm open-end shape is offset, with a lower profile to fit inside odd shaped dropouts
• Another really important function: It opens bottles
• 70mm long and fits into pockets and saddle bags
