I use the Race Face Rally FR, http://www.singletracks.com/mtbreviews/ … /2509.html. They are very comfortable, but more importantly, they don’t move. Once strapped in, they stay put. I have a friend who uses some Fox Titans and he’s constantly bitching about how they fall to his shoes. They only downside I see with the RF Rally pads is that they’re hot in the summer. Because of that, I’ve taken a break wearing them until it cools off. Honestly, besides the heat, after a few rides with them on, you don’t even know they’re there. I can’t disagree more with fat_billy. For me, knee pads don’t play a mental role. I wear them because I fall now and then. When I fall, I’d rather not get hurt. I can’t afford to be away from work because of a knee injury. In my opinion, it’s not about getting better or learning skills, the best riders in the world fall off their bikes, it’s about simple protection!
