My pack for a 'big ride day' usually goes something like this -
One spare valve inner (tubeless)
Valve core tool
3x Tyre levers
Length off Gaffa
Handul of zipties
Allen keys/multitool (with chaintool)
Spare inner cable
Spare hanger (Depends on the bike)
Small wipes (KFC)
Bit of string
Couple of M4, M5 bolts.
Spare set of cleats
Sounds a lot. But its not really, everyhting bar the pumps fits into an old goggle bag. Rest of pack is made up of food/water/clothing that obviously is dependent on weather and length of ride.
Amazing how many people are not carrying a spare inner cable - they weigh next to jack all...
Oh, and as above, I have been known to take a very small stove and mugh with me on occasions. And keep it secret, until that moment when your huddling behind a wall while someone fixes a flat in the freezing cold in the arse end of nowwhere. always goes down well -
"Hang on, what the hell have you got there Snotrag"
" This? Oh, im just mashing up, its a bit chilly "
