Oooh... it's an inner tube. No one really talks about the lowly innertube, often hidden from view but bearing the brunt of your enjoyment we really cannot inflate how important this unsung hero is.
When some people puncture they just swap out their tube for a brand new one, others will reach for their Tip Top puncture repair kit and keep that tube alive at all costs. Those that swapped out their tube will probably stop 1 minute down the road as they forgot to remove that pesky thorn. Those that patched will face at least another 2 flats before they get home because punctures always come in threes. Whichever type of rider you are it is always a good idea to carry a spare and a set of Pursuader tyre levers.
Never one to be stranded roadside; Prudence states that you should always have a spare at hand even for your faithfull tubeless set up, and who are we to argue with Prudence.
