What about proper bar width?! So important for your entire upper body, not just your wrists.
I was running bars that were too wide and putting excess strain on my shoulders + gave me arm pump. I cut the bars down to a width similar to what I would use for rowing, elbows behind my wrists so I could better engage my lats to stabilize my body.
My next bike upgrade is definitely SQLab backsweep 12 and their 711 grips that are hand size specific.
