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

No surprises, that's exactly what I expect from a replacement cassette. These things are durable, shift smoothly, and the 12-30 range is great for all but the most brutal of climbs. The Ultegra series strikes me as the perfect balance of weight and quality. Yes, the Dura-Ace is lighter, but I think the Ulterga lasts longer in the long run and although there are cheaper cassettes, I trust the shift quality of this cassette and have not regretted the purchase.
