General Information
This is one of the first modern compact crankset featuring a five-arm 110BCD spider where both inner and outer ring are removable. And unlike later alloy crankset prove to be quite stylish - vaguely reminding the shapes of Stronglight 93 or 105 cranksets. The drive side is not made of one single piece of forged alloy ; instead it consists of a spider crimped onto the right crank. This could prove less sturdy or reliable than a one-piece drive arm/spider but actually I have not heard of any incident and this crankset was extensively used on a mountain bike.
