Spyderman,
I certainly dont want to discourage you from one of our newest sponsers, but buy something else from them and dont waste your time with the 1 inch riser block. It is really hard to install, and there are better risers out there that are easier to install on give you more adjustability.
ESI has these in 3 or 4 inches and you can vary the angle:

And KewlMetal came out with a real nice set just as easy to install and even more adjustable 2-5 inches, you can vary the angle and you dont have to disassemble the reverse cable:

Either way, you gonna love a more upright postion.

I have the 4 inch ESI risers now, but would love to try the KewlMetal ones. It looks like acc's made to clamp on handlebars may also clamp on the risers. ie cupholders, GPS mounts, etc.
