Did you just ShartQ?

Probably the wrong thread, maybe the following is going to have a question:

I rode a metric century yesterday on my Grand Bois- 31mm tires, 40cm 25.4 tires, standard tubing… and I felt so beat up! Narrow bars, non-aero levers…
Is it my newbaum’s tape? Is it my narrow tires? Is it my narrow bars? I spent the last few weeks prior riding more upright, on some wide bars on my Gryphon with 2.35" tires, so maybe I just got too comfortable?
