Possible cause number 976 for on-bike creaking.
Just like their arm warmers, the Giordana Performance Silverline Knee Warmers have ergonomic paneling to deliver an ergonomic fit impossible to achieve with the tube-like knee warmer design most often seen in the marketplace. One panel starts at the quad and extends to just below the knee. Another is from the crook of the knee up to the hamstring, with a third going around the tibia and calf.
These knee covers use the same Super Roubaix fabric as their Body Clone cousins. Warm, plush, brushed on the inside, smooth on the outside; the classic warmer fabric. Good stretch, as it's a nylon-spandex blend.
The Silverline utilizes soft gripper elastic at the top and the bottom to secure the warmer around your knee. There is a front and rear to these warmers and the easiest way to get them right is to have the reflective Giordana logo on the outside of each lower leg. The panels are held together via flatlock stitching.
