asked by: a guest Will this work on a shimano grx crankset 46/30?
A.
anwered by: canteau The microSHIFT R9 Front Derailleur will not work with Shimano GRX, currently the only front derailleurs that work with the Shimano GRX group are Shimano's GRX due to the wider gear range.

Replaced the original broken part, worked perfectly. Shipping was fast, product was as described and the price was great! What more could you ask. Will do business with Tree Fort again. 5 stars
