Let's stoke it up a bit! Recently installed a B17 on a new Cannondale Quick. I've only got aroung 200 total miles on the bike. Proofide has been applied twice. I was looking at the saddle today and noticed that sit bone impressions are alredy visible. For me, the saddle was comfortable out of the box. Only adjustments made have been to raise the tip of the saddle to cure some minor chafing.
Lucky me!
