No matter your riding level, you can experience the high-level road shifting performance with Shimano chains and the updated 12-Speed 105 R7100-series components all reflect an overarching reassessment to one of the most reliable groupsets ever offered. The smooth, consistent gear steps remain a Shimano hallmark thanks to the addition of the 12th cog. Keeping things simple, the R7100-series rear derailleur is offered with a single cage length. One note on the rear derailleur and cassette options. Shimano is offering a 12-Speed Shimano HG-710 11-36T cassette for 105 R7100 as well. Quality is essentially the same, and it works with the same 11 and 12-speed freehub bodies, but it is only compatible with the R7150 Rear Derailleur, NOT with the Dura-Ace R9250 and Ultegra R8150 models.

With standard HG tooth profiling (the Dura-Ace and Ultegra 12-Speed cassettes feature HG+) and 105 Di2 shifting you can trust the system to shift with speed and precision pedaling during maximal efforts up a climb or nearing the finish line, local spring marker or approaching a solitary ride personal best. The R7100 105 12-Speed Cassette is compatible with Shimano 11-speed HG freehub bodies as well as the new Shimano 12-speed HG12 L2 road freehub body. All cogs are steel, nickel-plated for longevity, corrosion resistance and Shimano keeps the overall weight down with a single anodized aluminum spider to go along with some individual cogs and spacers. This is a high mileage, cost effective cassette that many Dura-Ace and Ultegra high mileage riders choose for training year round, in large part to enjoy the value on top of the steady shifting performance.
