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

This cassette is perfect for my needs. The 12-30T allows me to downshift once in both high and low gear. My bike originally came with an 11-28T cassette. This makes my compact twin (50-34) more manageable. I spent about the same amount of time on the higher and lower gear front sprocket. The low gear definitely helps me scale the Bay Area hills. I didn't need an extremely low gear (like a mountain bike) and I prefer minor rear gearing changes to the big, extremely low gear changes. Also, using the new cassette didn't require me to modify the chain.
