We have a few mantras, and one of them on the trail is: take only what you need. Now this may sound like it has profoundly deep meaning, and it can, but when it comes to bike tools, it's pretty simple. We'd rather not ride with 50lb packs filled with tools for the what-ifs, and Wolftooth's Pack Wrench Steel Hex Inserts let you size down without skipping necessities. High quality, weight conscious, ready to wrench.
