I love my Camelbak, I have a large capacity one (100 oz), which allows me to fill up water/ice twice to last me a whole day. It's so much better than having to carry around several bike-bottles.
Unfortunately, I have a neck spondolysis, and it is difficult (except with a lot of pain) to carry the water as a backpack the whole day. I have done it several times, but had a lot of neck pain and stiff neck for days later.
I was wondering and would like to solicit ideas bike tourers here have found or implemented during their tours to carry the water on the bike rather than on your shoulder/back.
I heard of a water pack called Hydrathon, which seems like an interesting way to carry water on the bike -- it's like a pannier but instead on the bike rack, you hang it on the frame of the bike. Also, it carries also a bit less water than what my camelbak is able to carry (2L vs my camelback which is about 3L), but still better than carrying it on the shoulder.
Any pictures/ideas people can share?
