The bottle that lives on a bench is not the one that goes in a saddlebag.

The workshop container

Large, stable, refilled from, opened often with dirty hands. 45 HDPE packers and 43 PE cylinder rounds, in the 250 to 1,000 mL range this shelf is good at.

The ride container

Small, light, leakproof under pressure and temperature change, and it lives against a spare tube in a bag that gets sat on.

Which the archetype describes exactly

"Travel decant. Leakproof under pressure change is the whole requirement." That sentence is right and the shelf has 17 containers at 15 mL or under to meet it.

So the gap is at the carrying end

Not the buying end. A rider wanting a 20 mL lube bottle for a jersey pocket is choosing from a very short list here.

Pressure change is real for cyclists

A ride that climbs a thousand metres is a pressure cycle, and a bag left in a hot car is a thermal one. Both find a closure that seals at a bench.

Test it in a sealed bag

Fill, seal, put it inside a clear bag, take it up a mountain and look at the bag. Anything that escaped is visible and attributable.

And bag it anyway

The camping property reaches the same conclusion: no closure is certain under repeated pressure cycling, and a small sealed bag costs a gram.

Climbing is the same problem in a different bag

Chalk in a pack, liquid chalk in a pocket, and a long approach in the sun. Dry powder escaping is less damaging than lube and just as annoying.

The dry half lives in the workshop

Small bike parts never leave the bench. 115 PET single wall jars, one size repeated, clear, labelled in numbers.

Buy for the two environments separately

They share almost nothing. The commonest mistake is buying one bottle type and expecting it to work on a bench and in a jersey pocket.

The archetype behind this shelf is store-liquid-decant: 15 to 120 mL, narrow mouth, flip top or disc top or lotion pump or fine mist, PET and HDPE, cold fill, thin, aqueous, poured, with "travel decant, leakproof under pressure change is the whole requirement" as its stated reason. It describes the two wet leaves at a travel scale, and the shelf is workshop sized: median 237 mL against a 120 mL ceiling.

The Davis Pack Supply catalog, measured 19 October 2026. The cycling and climbing shelf is 972 rows: 383 containers and 589 closures. 5 mL to 2,000 mL with a median of 237; 17 containers at 15 mL or under, 25 at 30 or under, 77 at 60 or under, 132 at 120 or under. 174 HDPE, 147 PET, 42 PP, 20 glass. 188 bottles, 173 jars, 17 tubs and pails, 3 jugs, 2 tubes. 137 white, 72 clear, 69 natural, 37 black, 33 amber. Closures: 381 continuous thread, 39 child resistant, 36 disc top, 26 dome lids, 26 spouted, 19 flip top, 13 spice caps, 11 liners and sealing discs, 9 phenolic.

Written from 16 CFR 1500.121 and 1500.14, and from the catalog as it stood on 19 October 2026. Whether a given lubricant or sealant is a hazardous substance under the Act is the formulator's determination, not ours. No point-size conversions appear here because the regulation specifies fractional inches as the height of a capital letter. Climbing area rules on chalk are set by land managers and vary site by site.
