Got this from our local news group.
The following are the email-conversation between a guy and Yeti for the
limitation/design fault:
From Yeti,
As I said you it only hit s the derailleur upon bottom out in the smallest
cog. You can descend in the smallest cog but there a small change if you
bottom out it will hit the front derailleur. At higher speeds that occur
during descending you should be in the middle to large cog to compensate for
those higher speeds. We do not consider this to be a design flaw. You ride
at your won risk.

Dear Mr Grant,
Since I do not receive your further reply, I reserve the right to claim for
any injury and bike damage caused by that design fault. If the smallest cog
cannot be used during descending, I would consider other frames like Santa
Cruz Blur LT.
Regards,
Michael

Hi Craig,
Thanks for your quick reply.
As you said, I can use the middle or largest cog to descend. If the smallest
cog is accidently used, it would be dangerous to me and damage the frame.
That risk should not exist in Mountain Biking, because it is really a
dangerous activity.
Best regards,
Michael

If the front derailleur is positioned properly on the seatube the only time
it can hit the swing arm is under full compression (bottom out) and in the
granny gear. Since the frame is usually only bottom when descending it is
not a problem, because when descending you will be in the middle or largest
cog.

Subject: 575 frame problem
Dear sirs,
I have brought a brand new Yeti 575 last week at your Hong Kong dealer.
However, I found a problem with the front derailleur. It hits the rear swing
arm (at about 4.5 inches travel) when the derailleur is placed at the lowest
position (ring 24 of 44/32/24 crankset). Then, I am forced to rise the front
derailleur to a higher position to allow enough gap for rear wing arm
traveling to 5.75 inches.
Based on the fact above, you should provide a special designed front
derailleur or redesign the rear swing arm to allow enough space for front
derailleur.
