TA 94mm BCD 5 Arm Compact Outer Chainring - Silver - 42T

Shimano compact drive. Made from 7075 T6 heat treated aluminium sheet, cut in the traditional manner on a lathe which produces a much better and more accurate tooth form than the pressing method which is used by most other chainring manufacturers. The teeth are higher and the deeper groove eliminates chain suck. The ring thickness has been increased from 3.5 to 4.0mm. This strengthens the area which is ramped to best effect.

Suitable for 9 speed.
