I put on D404s 2k miles ago. No noticeable wear yet.
The differeance between these and the stock B'stones
is amazing, it's a whole new bike. They feel solid.
Real good in the rain. No more WICKED head shake on
the decel. I've got way more confidence with these.
Make sure your rear axle is alinged, and the front
tire is balanced. Watch them balance it if you can.
I'm glad I did,
