Could it be aggravated by the riding position on your bikes?
I'm pretty sure it's unrelated as thankfully the shoulder doesn't hurt at all in my riding position. I've done over 100 miles this week after almost a months break due to crap weather and if anything it's improved the shoulder. The only thing I can think that might be related is about three months ago I hit a pot hole I'd not spotted until too late real hard on the MTB and very nearly fell off, that hurt both shoulders and my neck for a day or two, but everything got better, i.e. it was before the proper frozen shoulder arrived. I was amazed I didn't ding the wheel-rim to be honest, Mavic XC717s are really rather good!
