Here is my bike pack gear. I prefer to keep the weight off the frame to improve bike handling.
Total pack weight without food and water 7 lbs solo or 5lbs 9oz with partner sharing.
Gear:
Pack - zpacks zero backpack small with webbing belt and side compression straps
Tent - zpacks prototype tent 27 oz use bikes instead of poles (new hexamid duplex tent 25 oz w/2 poles)
Bag - zpacks 40 degree bag
Pad - NeoAir Xlite regular
Rain gear - zpacks cuben fiber jacket, pants, mitts
Insulation - Icebreaker long underwear, beanie, gloves
Socks - Heat holders thermal
Jacket - Patagonia nano puff pullover (inc. in weight but not in pic)
Gigapower stove, fuel, titanium cup, spork, backup matches
Bear bag and line
Toiletries bag - TP, tbrush, tpaste, sunscreen, bug juice, liquid soap
First aid bag - neosporin, bandaids, 4x4s, benadryl, dermabond, steristrips, and coban.
Pump - lezyne HP drive (with flexible hose)
Repair bag - derailleur hanger, chain link, cleat bolt, zip ties, duct tape, Lezyne carbon multitool.
Water purification - MSR aquatabs 30 min. 1 bottle on bike.
You could cut down on weight and forget hot food and leave the rain gear if the weather looks good. My son did ask why we were not bringing a frying pan and bacon.
The zpacks guys are great to work with and the gear has lots of options.
The pics are from a loop in the white clouds of Idaho (big and little boulder trails) with my teenage soon. A great time!
