In this video we are going to talk about… …the technology that has gone into designing… …that brand new 12-speed cassette. We’re going to look at the range… …and the different materials. If you look at the material that the cassette is manufactured from… …you’ll find that there are three different in there. The bottom four are all made from steel. And then when we get the full cassette body itself… …you’ll see that the next five gears are manufactured from titanium… …and then the top three are made from aluminium. This is just to make sure the cassette is as light as possible.
Let’s get into a little more of the details about the range of the cassette. The biggest one is a 51T, then a 45, 39, 33, 28, 24, 21, 18…..and then we go on to the singles…..that’s a 16, 14, 12 and then finally that tiny 10T. So that was the 10-51T cassette that we went over…..there’s also the option of the 10-45T. But that is everything covered…..and the technology that has gone into designing…..this brand new cassette. .
