The Shimano 105 R7000 is a mid-range option that offers a great balance of performance and affordability, making it ideal for recreational and intermediate cyclists. In contrast, the Ultegra R8000 is a higher-end series designed for serious cyclists who seek improved performance, lighter weight, and advanced technology. If you're looking for a more competitive edge and are willing to invest a bit more, Ultegra is the way to go.
Works perfectly with the 11-34 cassette and much lighter than my previous derailleur. Shifts very nicely.
