I run 520 on my road bike. I mainly ride a 35 mile paved national recreation trail way out in the desert and I like to get off my bike to scramble to the top of hills for better views. The 520 are a fine precision product. While you are at REI, take a look at these companion shoes. The clips do not tough the marble floors at my job, they are well ventilated and have ample traction in the tread. Great shoe.

After I get in some hiking today I'll ride the motorcycle over to REI and pick up a couple stealth blinkies I ordered last week. My guess is that's not all I'll walk out with.
Tomorrow I ride that River Mountain Trail. GREAT weather for the 3 day weekend.
BTW, I ride Wellpro BMX pedals on my commuter.
