***Wolftooth EnCase tool system: 14 function multi tool in right handlebar end; chainbreak and plug kit in left handlebar end, 2 quick links
***Giant Clutch Fork Storage: 25g CO2 with inflator head.
***Der Hangers: Both my in downtubes (2020 Enduro and 2020 Druid)
***Spare Cables: None (AXS with a spare battery in each downtube)
***Tubes: None (CushCore on Enduro....not going to ever do a field tube, run flat out; Zip 3Zero Motos on Druid w/ DD casings, haven't pinched since running these hoops)
***Water: I run XL frames w/ bottle cages that will mount as far south as possible (blackburn and woftooth make versions). This allows me to EASILY run a 1L bottle
***Snacks and phone: Pocket
The above strategy has me comfy up to 20 miles/3hrs in terrain that will eat bike parts. Any more than that and I will grab a fanny or a SWAT bib. I know it's not for everyone, but all of my bikes are fully self sufficient, and every discipline has it's "go" bag with shoes, clothes and accessories staged and ready to go, so that when the moment presents itself, i can seize the moment. That's probably and extra $250 per discipline: mountain, road, and dirt jump.
