Bit the bullet today and succumbed to my (perhaps irrational) desire for internally routed dropper-post stealthiness, seeing as my Mojo HD isn't set up for such things, I had to do a bit of 'modding'... this involved drilling out the lower bottle cage mount and then punching a hole ( ) through an internal thin sheet of carbon (I'm assuming/hoping 'leftover' from the layup, i.e. not structural!! It can't have been as it was very thin... ). End result is pretty neat I think, just need to work out a way of guarding the cable as it's exposed to rocks etc (and we have plenty of them on our trails here!)
Anyone else taken the drill/tools to their bikes to instal an internally routed dropper?
