Very good to know Muirenn, they do seem to have different models for Tri and other bikes. Didn't get to ride tonight, we just had a major thunderstorm and things are now a mess. Hopefully tomorrow after work I can conduct my experiment.
Rode today with no hydration pack, just a water bottle & stopped when I needed to drink. While my neck/trap was less troublesome than when I use the pack, it was still a problem but NO neurological symptoms however. So, for now, it appears that one hour is about my riding limit. Well, I will take it! Riding for one hour is far better than NO riding. I just need to change my purpose for riding in the first place. So, for now, it will simply need to be for joy and stress relief and keep the more serious exercise to my other activities that I can do without pain. This doesn't mean that this won't resolve as I deal with my shoulder however, this doesn't have to be permanent!
