I have a variety of knee and elbow pads starting at $29. POC, RaceFace, IXS and others. New and used. Try some on.
GForm ELine. These were $129 plus tax. I have Small, Medium and Large. These are new. Can put these on without removing shoes, a feature that is under rated until you use them.
Small $89
Medium $89
Large $79
My thoughts. INCREDIBLY COMFORTABLE for pads that offer so much impact protection. Like landing on pillows, but deceivingly slim. Mine dont move, straps really work.
I am 175lb on mediums. If you are a pro over 160lb, or normal rider over 185lb, the Large will probably fit. The small are likely to fit under 160lb
