qtaroqhoji: Frame Design and Construction The most noticeable feature of the Stache’s aluminum frame is the elevated driveside chainstay, a design element that experienced a brief era of popularity in the 1990s before being superseded by the now-ubiquitous double diamond configuration. The elevated stay on the Stache combined with the heavily manipulated seat tube are what allow for such a short rear end, due to the fact that potential issues with chainring and/or tire clearance are eliminated. To help maintain the frame’s stiffness, the PressFit 92 bottom bracket shell and a section of the non-driveside chainstay are forged from one single piece of aluminum. To provide even more tire clearance, the rear portion of the bottom bracket shell is squared off, creating a few extra millimeters of space.
