I'll probably catch a bit of grief for even asking this but now 16k miles into what has mostly been a really fantastic voyage with the GT, having to make some decisions. My lower back just keeps giving me fits and I've injured it several times in the last 2 years. Anymore, the bike is still fantastic around town and fun weekend drives; yet, touring or long trips with the bike is running into some problems. I'm either going to have to make adjustments to the GT or consider getting another bike as my lower back will simply not let me ride a bike - for any extended time period - that has any, even remotely forward lean to the grips. Even with the touring handlebars I'm still slightly bent forward. My back wants to be straight up and down. The 250 mile ride back to home this weekend was maddening and dangerous as it saw me for extended time periods even raising up and driving the bike on the slab with only one hand on the throttle, giving my lower back a rest. From that upright, deadly one arm driving position, my back felt fine. Again and again I tried to estimate how much distance I'd have to add to the bars to try and get me to that upright position on the GT. I've already got the touring bars that put you in a more upright position and the touring shield I have on there raises the bars even more; yet, it's still not enough and I dunno if I can even add risers after the touring bars and the shield already? I've also tilted the bars back towards me a bit too. Any suggestions would be helpful. And yes, I'm working on the back thing myself as I've tried anti-inflammatory meds and am still trying some physical rehab stuff to try and strenghthen it.
