"Oh Shit" moments...

I had drilled a hole in my Nitto handle bar for a brake cable. I've cycled with it for over a year, but it gave up yesterday when I was climbing the slope from the basement where my bike was stalled. Fortunately, I did not fall.

I'd dissuade anyone from drilling holes in handle bars....

Glad you didnt get hurt M1, Drilled STEMS are common, Ive drilled a couple myself and sometimes sheet ally is drilled to STOP a crack, but we live and learn.
