Currently using 11 speed setup and upgrading to the GX Eagle this week, will my 11 speed trigger shifter work with the eagle setup ?

Your trigger has 11 clicks and Eagle has 12 gears so no. GX eagle shifters are a sensible price though

Cheers Mike.. I’ve got the budget 12 speed grip shifter on its way for the time being

Having run the GX grip for 4000km on the 11sp I’d have no issues getting the GX grip on the 12sp – only hassle I’ve had is not finding replacement grip parts when that gets worn
