What? A ceramic bearing design for the streets?

Enter the Isotope ceramic hybrid series. A bearing designed for the high impact street/park skater that is looking for the speed and performance of a ceramic bearing with the mechanical durability of an all metal design. It’s a highly versatile bearing offering unparalleled performance on street sessions to backyard ramp jams.

As with the Metallics and Atoms, we start with high purity, high quality carbon steel for the inner/outer rings, doped ZrO2 ceramic roller balls for frictional/thermal/shock/impact resistance, and high tensile strength engineered retainers - these bearings are a great balance of flow and mechanical strength and serve as an excellent choice for street and park skaters alike.

Each bearing is coated using our GraphFlo(TM) process and “burned” in at high speeds. All of our bearings are 100% tested before they are packaged/shipped to ensure consistency and 100% performance right out of the box.

Each Isotope Series Bearing Kit Includes:

  • 8 x isotope hybrid-ceramic series bearings with GraphFlo(TM) ceramic technology

  • 8 x isotope series bearing shields with micro-ring for easy application of lube while bearing is in wheel (installed)

  • 8 x speed washers

  • 3 stickers

Very short and very good
Format: eTextbook
I read this book or one similar to it my senior year in high school 1970. It absolutely caught my attention as a way to explain why the continents had separated from Gondwanaland. I really liked revisiting the theory in light of the advances made since then

I love VSI on Kindle
Format: eTextbook
The thing is they take a long time to read because of the look up feature. It's like reading a book in the Library of Congress.

There are few who are capable of telling the story ...
Format: Paperback
There are few who are capable of telling the story of plate techtonics including critical details. Peter Molnar is one of those chosen few who can deliver such a story succinctly and precisely.

Very nice, but very short, book on the subject.
Format: Paperback
This is a very nice, but very short, book on the subject. I learned quite a bit and enough to delve into structural geology and related subjects.

Excellent 120 pages book on a complex subject.
Format: Paperback
I thought this was an excellent 120 pages book on a complex subject. It discusses a variety of subjects besides the title of plate tectonics and which are related to it: continental drift, oceanic seafloor spreading, fracture zones, subduction of tectonic plate edges, faulting, the creation of mountains and plateaus, earthquakes, volcanism, oceanic magnetic anomalies, and the locations of concentrated metallic ores. The text is accompanied by almost 40 sketches and diagrams elaborating on the discussions provided in the text. The book also introduces the grand concepts of Earth geology such as the mantle, lithosphere, and asthenosphere. It also provides a short history of the development of the concept of plate tectonics. Finally, the book provides specific detailed descriptions of the formation of major mountain ranges and plateaus such as the Himalayas, the Tibetan Plateau, Tien Shan, the Tarim Basin, the movement of Eastern Asia, the Andes, and the western US mountain ranges. It also gives a short description of the movement of India from the eastern edge of the African Plate to the Eurasian Plate over the past 90+ million years.
