Im curious to know how much of a difference the ideal front derailleur angle really makes for a mountain bike wheel. Is it really worth obsessing over, or is it just a minor tweak that only makes a difference to the most elite riders? I mean, lets be real, how many of us are actually pushing the limits of our bikes to the point where a slightly off-kilter derailleur is going to make a noticeable difference? And what even is the ideal angle, anyway? Is it the same for a 2x10 setup as it is for a 1x12? Does it change depending on the type of riding youre doing, or the size of the chainrings? Ive seen some people swear by the rule of thumb that the derailleur should be parallel to the chainrings, while others claim thats a myth with no basis in reality. Can we settle this once and for all? Whats the actual, measurable impact of a misaligned front derailleur on a mountain bike, and how critical is it to get it just right? And lets not even get started on the whole roadies and their precision thing - I mean, come on, guys, its not like a 1mm difference in derailleur angle is going to make or break your ride. Or am I wrong?
