Shimano Tiagra 4650 inner chainring is designed for the compact version of the
Tiagra crankset. Shimano 10-speed chainrings use their SG-X chainring tooth profile for quicker shifting.
The
4650 and 4600 double chainrings are not interchangeable because the 4650 uses a compact 110mm BCD 5-bolt vs the 130mm BCD 5-bolt of the full gear Tiagra 4600. The
Tiagra 4650 inner chainring is made to be paired to the
Tiagra 4650 50t outer chainring.
