The brake lever hack It is literally 2 holes drilled with a cordless drill. I didn’t even take the levers apart. The part to worry about is where to drill and what size holes to make. You need to remove a circlip to remove the barrel shaped cable stop. There are 2 bushings, one for each side, that determine the required hole sizes. The larger hole has to be positioned so that the bushing and circlip can be reinstalled in the new location, and there isn’t much room. It is a little fiddly to then install the cables, but it’s doable. If there is enough interest I could try to create an illustrated guide.
