Does the one-size-fits-all approach to triathlon bike bar width really hold up to scrutiny, or are we doing ourselves a disservice by not considering individual rider needs and preferences, and if we do consider individual needs, what are the key factors that determine the ideal bar width, is it solely based on shoulder width, or do other factors such as hand size, riding style, and even specific disciplines within triathlon play a role, and are there any benefits to deviating from the traditional 38-42cm range, or is this range truly the sweet spot for most riders.
