True. They are like no other components I can think of, from that point of view. It also amazes me that the most vociferous objections to them, seem to come from those with demonstrably the least experience of them, actually riding with them. It’s very odd, but I attribute it to the fact that the more shouty people are, on the internet at least, about a subject / item, the less likely they are to be able to demonstrate how it is they form that opinion, and shouty internet people tend to be the type that don’t take being made to look daft, by opposite opinions, given by people with indisputable evidence / experience of the subject / item, well at all. That’s the internet in general to a large degree, but cycling type forums seem to attract more of them, from my point of view.
