So I have become the defacto "wrench" of our anual bike trip across Wisc. I bring a tool box carrying most of my tools. I also throw in some spare parts, but am discovering I don't always have the exact part I need sometimes. I'm making a list (and checking it twice) of typical spare parts experience has shown me to be needed. This trip has few/no high-end racing bikes but is mostly older adult and kid bikes of all types. This is just a parts list. I have lots of tools.

Spare cables and housings and end caps and crimps (some complete kits, some raw materials)
rim tape
Chainring bolts
small assortment of metric bolts and nuts
QR skewer assortment
2 chains (5-8 speed, 9 speed)
canti brake noodles
spare sets of canti and V brakes.
V brake noodles
brake post end bolts
electrical tape for wraps that come loose
bar wrap end caps
hose clamps
cable ties
tubes (20,24,26,700,27)
spoke assortment (just happen to have lots, so I bring them)
goop hand cleaner, rags

anybody notice a glaring omission?

How about some cheap spare tires? A couple handlebars (road and MTB)? A few stems? A couple sets of platform pedals? An old rear derailler? A bar end friction shifter? Brake shoes? Tire boots? Bearing balls? Some spare saddles? Some spare wheels?

Seat post binder bolt or qr

I think the bearing balls (1/4" and 3/16"), tire boots, seatpost binder bolt, and possibly some chain replacement pins would be good additions.

I assume oil, chain lube, grease and a floor pump (with Schrader adapter or dual head) are included with your tools.

How about a few of the metric flat head machine screws used to fasten cleats to cycling shoes? Zip ties?

Yep, 3 missing.

Duct tape! It has saved my butt many times from patching the tire so the tube would not puncture. Just wrap your seat post a couple of times.

A map of local bike shops in case something happens.

And a cell phone to call the wife to come and get you!

Good luck & I am jealous, it sounds like a ton of fun!!

skeeter

what are you going to do with those *spokes* with out a spoke wrench??
liners for those brake noodles.
all that & no tire inflation device & spare tires??

QR skewer assortment - only an extra bolt seems necessary(in case you lose it), I do not see the skewer failing.

2 chains - you only need extra links. only a 9 sp is really usefull as it will work on any bike until you get to a bike shop.

spare sets of canti and V brakes. - why?

The nuts and bolts make sense as they are things that fall off bikes.

No. Duct tape.

I'd also include some wet wipes of some sort, but that's because I don't like the residue that Goop hand cleaner leaves on my hands. Doubly true if I might be on the road and needing to resume riding after using it.

If it is for a group, I would add:

– Tire boots, as they can easily save a tiire for a few days;

– Tubes : tubes are elastic, so you are able to get away with 700x25-38 (also works on 27") and 26x2"; the need for 24", 20" and 16" (BOB and Burley trailers) depend on who you have. Maybe people should be required to carry 1-2 tubes?

– Tires: a couple of foldable ones in 26" and 700c should be sufficient. Children on trailercycles aren't likely to go through tires, but adults on 20"-recumbents are.

– Chain tool and powelinks (or whatever favourite you like to mend chains). I had 3 Shimano chains breaks so far, and if the chain looks good, a quick repair should last beyond the trip.

– Tandem-length cables. I have a single with bar-end shifters and I need a 3-m long shifter cable for the rear derailleur. Typical single-bike rear derailleur cables are 2 or 2.2 m long and the most common "tandem-length" derailleur cables sold around here are 2.65 m long, which is just 15 cm too short for my bike.

– QR. I had two fail on me. Never the nut, BTW. In one case, there was a problem with threading and at one point, the nut screwed in nothing; turned out the threads were unevenly machined and partly stripped. In another case, the tiny C-ring that kept the cam lever in place fell off or broke when I had remove the wheel; that meant nothing but good will kept the cam lever in place.

– Tools, including headset and bottom bracket tools; a lot depends on whether people mostly come with decent bikes or not.

– Gloves. Nitrile gloves are best to work on greasy parts, but for all-around bike repairs, I prefer tightly woven cotton gloves with little anti-slip dots on the indise. They are great for everything except maybe soaking your hands in grease and you get much less sweaty than with nitrile gloves.

I would suggest adding at least one road lever, and one lever each for v-brakes and cantilevers. Older, low-end levers are probably best, because the left and right levers are essentially interchangeable. (I hope that you don't need to use them, because I've never busted one without crashing.)

I once walked home because of a busted freewheel, but I've never heard of anybody else getting stuck by one.

Maybe I missed it, but I couldn't find any mention of tube patches in this thread.

You mentioned that kids will be around, so you might want to set a good example by throwing in a pair of safety glasses (and actually using them).
