I other fun stuff, I'm slowly building a tool kit for when I am commuting to take care of most problems on the road.

• Road Runner goodie bag jersey pouch
• Victorinox Bike tool with various bits. I can probably save some weight here by removing the tyre levers.
• Knipex Mini Pliers Wrench
• Wolf Tooth Components pack pliers for chains and holding master links.
• Schwalbe tyre levers. These are awesome for putting tyres back on as they can be clipped onto the hooks of the rim and prevent the tyre from slipping off again.
• Schwalbe airmax pro digital pressure meter
• Park Tool SW40 4-sided spoke wrench
• Contec security skewer remover
• 4 nitril gloves
• Zip ties
• Replacement brake pads
• Small bag with spoke nipples and pump adapter
• Backup shifter cable
• Duct tape
• Glueless patches

Total weight: 450 gram (15.9 oz)

All I need now is a brake cable and a chain tool but that will probably be the Park Tool CT5 mini chain tool.
For touring I might add a crank puller as the Specialites TA has 23mm threading instead of the common 22mm but I am not spending €50-60 on a Stein Crank Extractor right now when I have the VAR version.
