The TA Specialite Zehpyr Road middle chainring, 110 mm bolt circle, 38 teeth, black
Unlike the MTB Zephyr chainrings, these TA Specialite chainrings for compact road bike cranksets are manufactured without shifting aids. With 2-speed cranksets, no shifting aids are required on the small chainring.
Compatible with 8-, 9- and 10-speed road bike cranksets:
The compact chainrings are designed for 9-speed chains, but can also be used without any problems with 8- and 10-speed chains and cranksets. On the cranksets, the distance between the chainrings is determined by the crank arms. Therefore, it does not matter whether you use 8-speed, 9-speed or 10-speed chainrings.
