It’s only recently (last 2yrs) I’ve looked in my camelback and thought ‘why do I carry this much crap?’
Gerber multi-tool with pliers
Standard multi tool
2xtubes
Puncture repair kit (although I run tubeless)
Shock pump
Regular pump
Jacket (in all seasons)
Zip ties
Gels and energy bar
old gel wrapper (for ripped Tyre)
Cash (notes and change)
Phone
Spare bolt assortment
2x quick links
And a spear come links of chain
+2.5 ltrs of water (again all seasons)
Now I’ve a fully rigid fat bike, I’m starting to pair down my kit, food and spares to what I can easily carry on the bike only:
1xtube – carried on a backcountry research super 8 (fat bike tubes are to big to fit in a regular way)
Zip ties in the crank axel
Tool pack with multi tool, cash and a spare energy bar etc under the seat (dropper compatable)
Chain link taped to a cable
And upto 1.5 ltrs of liquid in bottles on the bike.
Pump on a mount on the frame.
Phone and food in pockets.
If I need to I stick a frame bag on for larger rides or when the weather is changeable for clothing.
This has revolutionised the way I ride to some degree – no bouncy pack and sweaty back!
