What are the key considerations when selecting a handlebar thats compatible with a mountain bikes travel and axle type, and how do different handlebar designs impact the bikes overall handling and performance? Should I prioritize a handlebars rise, sweep, and width, or are there other factors such as material, clamp diameter, and ergonomic features that play a more critical role in determining the best handlebar for my specific mountain bike setup? For instance, do wider handlebars with more pronounced sweep angles provide better control and leverage on technical trails, or do narrower handlebars with less sweep offer improved precision and responsiveness on tighter singletrack? How do different axle types, such as quick-release or thru-axle, influence handlebar selection, and are there specific handlebar designs that cater better to certain axle configurations?
