I carry the basics listed above, also a 15/16" combination wrench to loosen the rear wheel nut to adjust the chain. I don't know what 15/16" converts to in mm, but it fits. A little 6-8 mm ratcheting wrench to adjust the chain tensioner bolts and a tire air gauge. I also carry an extra qt of 20-50 oil, but have never had to use it.
