Hi, I am a multi-cyclesport rider... I am tall and am increasing my crank length.. problem is I have 6 bikes... I know shimano made 180mm XT cranks at one time or another and there are lots of other out there who made crank lengths longer than 175mm... anyway if anyone here has old MTB cranks longer then 175 I'd like to purchase them from you.. old XTs are great for my touring bike! PM me.
