Angle on the sea looks like the nose is tipped down. Put a level on it and then ride for a while.

Good shorts a must, but likely the cause of your chafing is your butt needs to get broken in to saddle time. A good lubricant is Glide, a persistent anti-chafing ointment used by triathletes.

Very nice bike, as BTW. Somebody gave you good advice. I lust after the SL7 with Di2.
