No more scars
I feel like I got really lucky, as these are the only knee/shin guards I have ever purchased; and they rock! Heck, I even got the size right the first time. I haven't taken a serious spill with these yet, but they have saved my shins from acquiring new scars from slipping a pedal. I also feel like I ride a bit more aggressively due to the fact that my legs are protected. That might just be all in my head, but whatever.
The strap system is quite impressive. It keeps everything in place; even when riding XC there is only minimal shift. During my last 3-4 hour ride I think I re-adjusted them just a couple times, which seems to be a lot less than some other products.
