Grip thickness and bar sweep change wrist angle, and a mismatched combination can cause discomfort on longer rides. That makes grip choice more than a matter of which one looks appealing. Thick versus thin is not a one-size-fits-all decision; hand size and riding position are part of what I would weigh. The bar and grip seem like a pair to me, not two separate choices.
I’d rather compare options in person than guess from a catalogue photo; even a brief try would tell me more than the diameter label alone. How do you compare thicker and thinner grips against the sweep of your bars before settling on one?
