Shimano offers sprockets from the 105 FC-R7100 12-speed road bike groupset as spare parts. Available in two tooth counts, 34 and 36 teeth, the small sprocket must be paired with the large sprocket corresponding to the correct gear ratio. The 36-tooth chainring must only be fitted with the 52-tooth large chainring, and the 34-tooth with the 50-tooth.
The shape of the Shimano FC-R7100 small chainring is exclusively designed for the FC-R7100 12-speed crankset and cannot be fitted to any other crankset, even one from Shimano.
