Shimano-105 5800 STI 11 Speed Upgrade Kit

With Shimano 11-speed technology, shifting is made smoother and more progressive. There are fewer big jumps in cog size on the cassette allowing you to have one cassette that can "do it all!"

With an 11-speed 11x28 cassette, you still keep your 11x25 gearing, but with a 27t cog tacked on the top that makes it perfect for climbing in addition to casual riding. 11-speed cassettes also offer a bigger range of gearing options that make it easier to find that comfortable cadence in any variety of conditions!
