you can kind of see it in this one:

looks above the first 3 in the 303

When the revised the 2 rail bike in 07, iir, they made the top tube too thin. I noticed it on the pro's bikes at a national and couldnt figure out what happneed. after 2 races on my bike (semi-pro) i had what looked like a large dent on my top tube. At first i thought i hit it on something but there was ZERO scratches where something would have impacted it. At the next national i was at i asked one of the yeti pros what was going on and they called it the "bird bath" ... apparently it was happening on all of the frames. the force from the upper rail was compressing the top tube and it was denting upon itself. i called yeti and they did NOTHING about it. the only reason i didnt pursue it was out of respect of my LBS and their relationship with yeti.

It was a coment for Si Pardon who write the write up, He knows that I ment. I is a Sealed Drive that Shimano should make.

Yes

Fox has an oil that is specifically designed for the Kashima forks. That would be best, but If you can't get that any high end 10wt. is fine. I like Motul and Torco.
