The Chube 

A good problem with a delicate mantel. I am not sure you need to tape up like the guys in the photo did though.

this is a great boulder problem, but i have always disagreed with the v2 rating. i am certain this problem is more on par with j-tree 5.10 not mid 11.

A nice problem where the holds become smaller and smaller as you go. Felt the mantel wasn't too bad - just mentally commiting.

On the FA, the crux was a grain battle on the summit. A fall in to the yucca/nolina/pointy thing at the base would have been a problem. Before the V grades, we thought this was about 5.10. Walling and Moffat on the FA, early 80's. Named after the "Tube" also known as the London Underground Railway. Moffat and that funny accent always pronounced it "chube" instead of the American version, "toob".

No need to jump off for the descent. You can downclimb low angle friction (5.7 ish) almost directly opposite the problem on a blunt arete type feature that leads down to an adjacent small boulder about 6' off the ground. The downclimb is worn and pretty obvious.

Russ, Thanks for the historical tidbit!

AKA "The Tube" in the early Fry bouldering guidebook.

V2 does seem generous now that no one will ever grain battle on this thing again.
