I just purchased a Knolly Cache gravel bike with limited edition silver Shimano GRX groupset installed.

I would like to run a dropper post on this frame.

Shimano has made GRX left brake levers with dropper actuator built in, such as mentioned here: https://bike.shimano.com/products/components/pdp.P-ST-RX810-LA.html

But i am not sure if my silver GRX has that function.

Are all GRX 810 left brake levers equipped with the dropper function?

  1. There were 3 versions of the lever: 1x, where the lever blade was fixed; 2x, where the main lever blade pivots and there’s a second lever for shifting; and the dropper post one, where the main lever blade pivots but there’s no second lever for shifting. Hopefully from that you can tell which one you have.
