The other week I installed a bottle cage* to my Dahon. I thought it would save me a little bit of time by removing the need to stop and fish around in my rucksack for a drink. Indeed it has been very successful and I can now drink when the fancy takes me without needing to stop. However, when taking a drink after a hard climb or fast sprint (which is pretty much the only time I'd bother) the sensation is not unlike what it must feel like to be water-boarded! I find myself hastily swallowing much-needed fluids in order to gasp desperately for air immediately afterwards. Horrible!
Surely it can't be possible to drink and breathe through tour nose at the same time?
*Incidentally, I bought it from Wiggle online (http://www.wiggle.co.uk/) whose service I cannot fault. It was a very small order but was dispatched promptly and came complete with a couple of free bags of Haribo sweets. Awesome!
