Shimano 105 CS-5800 11 Speed Cassette 11-28t - OUT OF BOX Shoe Brand_Oofos RHEON Low Density LayerThe advent of the latest Shimano 105 groupset meant re engineering the 105 cassettes to work with the 11 speed configuration. The new CS 5800 cassette not only features one more cog, it was also designed to optimize shifting across the entire range of gears. The CS 5800 features the same gear thickness as the cogs on the 10 speed cassette. The ratios of the three different cassettes were looked at to ensure that the shifting between them is similar.
