Hi there,
I'm overhauling the front hub on my bike and I've noticed a small hole in one of the cones (see the picture linked to below). Should I replace it (I think yes)? If so, should I replace the other one too?

I can't post URLs or pictures, but you can paste the beginning of the address posted at the bottom of this message into your web browser to see the cone (please hover over the picture and click the right button on your mouse or, if you're using a mobile device, tap the picture and hold it till a menu pops up, select see the picture and zoom in as much as possible to see the hole). Hope this works.
