Thank you for your insight.. and extremly important, and riviting, social comentary on the motivations of people who ask questions here..
Another reason people sometimes go to compact cranks are ..... because they come pre-equipped on bikes that have a great price on them .... and sometimes purchasers have realy old bikes that have completly worn out drive trains and are beyond... salvage, and / or, safe use..
when that person sees they have a cassett that has 10 speed instead of 7 (like they might have had on their old 52-39 machine) ..... they are happy to have sooooo many more.... gears.. to choose from..
and wearing out that new ....drive train is exactly what they endend to do .... as fast as possible!!!!
