Review on 🚲 Enhanced Shimano CS-6700 Ultegra 10-Speed Bicycle Cassette for Optimal Performance by Adam Gardner

I have been riding for two years and average 3500 miles a year. I have a Trek Domane 4.5 from 11-28 105 that came stock with the bike. I live in the Central Valley of California where riding is no different than riding flat. Riding through the hilly and mountainous areas of the Sierra Nevada, Pacific Rim and along the coast, I fight at a high level and wish I had extra gear. The answer was the Shimano CS-6700 Ultegra 12-30T 10-speed cassette. When I needed it 30 were there to help me. Don't get me wrong, I'm missing 11-28 for descents and top speed. Changing the cassette was easy with the right tool. I made a small adjustment to the B button, it works great.
