In the world of suspension, there are lots of measurement-based articles out there for setting up your bike. But when it comes to handlebars most articles seem to follow an 'adjust to taste' rule. Given the huge range of different handlebar designs, risers, lengths, etc., does anyone know of a more evidence-driven answer for optimizing handlebar setup - e.g. based on arm length, torso length, height, ride style etc? I'm not 100% happy with my 610 handlebars, but its expensive to buy e.g. risers or longer bars only to find they are the wrong answer. Barring an empirical answer, perhaps folks can post their own experiences.
My rule of thumb is to experiment and use whatever is most comfortable in your most common riding position and narrow enough not to catch every tree on the way by... Experimenting usually involves having someone hold the bars from the front, floating them in space to find your best position...
