Thanks!
One of the redeeming qualities of social media and forums like this is the ability to tap into the experiences of others for advice that have experienced similar physical problems and injuries; folks that you might not have come across any other way.
I used to be pretty picky on fit and adjustments, everything had to be setup perfectly based on many years of riding, reading, and various fit clinics. Now, everything is pretty much thrown out the window ... whatever works is my new motto. After several hours of riding, I find that it begins to be tough to hold my head up - something like they called 'Shermer Neck' from my RAAM racing days where your neck starts to give way. I describe it as feeling a bit like a bowling ball on your neck/shoulders but there is no strength to support it. I've tried all the usual ideas to try and strengthen my neck (physical therapy, the gym, etc.), as well as various heat creams, 'cold' creams, tens units, massage units, heat/cold packs, etc. before and after rides. But nothing has proven particularly great in solving the chronic, low-grade 7-24 pain. At this point, I'm just trying to minimize the discomfort while still being somewhat efficient on the bike. It would be nice to do group rides again (even if I have to sit on the back), something I haven't been able to do for years - and I really miss that social aspect of riding. But I need to build up something in the low (or sub) 20 lb range to be able to hang with any casual group. I'm not ready to give up yet and forgo my passion for cycling!
