Purchased: 2 latex inner tubes at an eye watering price
Spent: A long time prepping the rims to perfection as I’ve read so much about how easy it is to pop latex tubes
Ridden: About 5 miles from Innerleithen to Peebles. I had been planning to do the Tour o the Borders top loop to see if the tubes were any faster. However the very loud pop from my rear wheel in Peebles scuppered that. I had one spare tube which was fine, but after that I didn’t fancy my chances of making it another 50 miles on the other latex tube, so I retreated back to Innerleithen. Had been looking forward to a great ride too, dammit.
So my conclusion was latex: sod it. Chuck a butyl tube in there and forget about it.
