To be fair I’ve got the Troy Lee KG5400s and they are just the knee pads, not the added shins that the 5450 have. They’re light weight , barely noticeable when riding and can be worn all day easily. IMO they are a trail knee pad only due to the lightness off them. If you were looking at doing and DH riding then you’d be better looking at a more DH/Park focused pad.
Should clarify – I caught my left knee on some hard part of the frame – coverage from the Troy Lees is good on the front of the kneecap itself, but where I got hit was on the side of the left kneecap, almost underneath it – the protection doesn’t quite warp around the knee enough, so it really only protects if you fall right on the knee.
Similarly, impact to the right knee was just above the kneecap, and again seemed to slip past the protection.
Yes, I particularly unlucky to get past the protection on both knees in the same crash. I have a gift.
