Just curious.
1. Fork: Many (non-mountain) forks are rated for 160mm.

2. Rear triangle: I recently learned the hard way that there just wasn't enough room for my post-mount caliper, adapter, and 160mm discs.

So I coughed up for some new Ultegra calipers.

Now I have two flat to post 160mm adapters if anyone wants them.
