The unique nesting and ultralight Daysaver multi-tool gets much more capable with a new Coworking5 add-on, delivering five more key trailside repair functions. Essentially, by tucking both the original L-wrench body AND all of the new tools into a single beefed-up tire lever, the new Daysaver Coworking5 multitool doesn’t even take up much more space in your bag or pocket. And again, it’s modular and surprisingly lightweight…

Developed as an extension for the 9-function original 45g Daysaver multi-tool, the new Coworking5 adds 5 more functions and just 30g, raising it from the realm of minimalist mini-tool to full-featured ride-saving multitool. And it’s really simple.

Now on top of every size hex/torx you need on the bike, the more complete Daysaver Coworking5 multitool adds a chainbreaker, spoke & valve core tools, plus a tire lever and spare chain link storage.
Tech details
The chain tool was the driving force behind the Coworking5 addition. And using the tire lever as a long supportive handle that also includes molded-in supports for the chain’s links, it actually looks like an actually usable chain breaker vs. the tiny solutions in some multi-tools. The 3mm from the Daysaver Multitool drives the pin to remove damaged links from 9-12-speed chains, including SRAM flattop (and in all likelihood Campy & Rotor 13sp too.)
The carefully refined Coworking5 design is based on a glass fiber reinforced plastic tire lever as a body, into which a machined & hardened stainless steel chainbreaker head nests. In the thinner center of the lever, a small magnet and holes on either side secure in place a chain master link. Machined into the chain tool head is a #0 spoke nipple wrench slot (3.23mm), and another hole underneath the chainbreaker to remove a valve core.
