Surly Singleator szerszám
The production of our stainless steel chainrings generates a lot of scrap material, so we decided to use some of it to make the Singleator Tool.
This polished and laser-etched tool sports an 18mm open-end wrench on one end...for adjusting the tension on a Singleator, and a bottle opener on the other end.
It’s compact (because you don’t need to put a lot of tension on a Singleator spring), so it easily fits in a tool kit, in a pocket, or on a keychain.
