In a bend element for a
flume-type waterslide, the bend element defining a bend with a bent sliding path for a rider between a bend-entry portion and a bend-exit portion of the bend element, wherein the bend element, in an apex region of the bend, has an asymmetric geometry in cross section, in which the
radius (r2) in cross section is increased on its outer side, which increased
radius (r2) is greater than the
radius (r1) in cross section of the bend element on its inner side, the bend-entry portion and the bend-exit portion have axes of entry into the bend and of exit from the bend that cross each other at an inner bend-angle of at least 90°.
