Is there a reason not to have some of this stuff in jersey pockets? I have spare tube, leavers, patches, tyre boot and multi tool in my posterior man satchel. Everything else* is kept in jersey pockets - alot of it in a Lezyne caddy sack.
*Cable ties, quick link, CO2, presta valve extender, another tube, phone, food, keys, torque key, iburpofen. Food in right hand pocket, tube and phone in a freezer bag in left hand pocket with the rest in the caddy sack in the centre pocket. This gives me enough room to fit a rain jacket in the left hand pocket should I wish. Pump is on the bike.
