Just dropped 76g from previous tool (96g bell: 3,4,5,6,philips) to my new setup (20g rusty 4,5 allens I found on the road)
My bike doesn't have 6mm bolts, the only 3mm is the brake centering bolt, philips only on the ders...
I was looking into getting a nice multi-tool, and almost bought one on friday, but realized that I don't need much else. Tires come off by hand, chain tool and spoke wrench for "just in case" I'll do without.
