About 15 years ago, I bought a Shimano 105 brand new crankset from Jenson for about $30 -- one of those periodic parts purges getting rid of older model year stuff, I suspect -- it was the original Octalink and likely had already been superceded by Octalink 2.0. A couple years later, I found the matching 105 Octalink BB. Installed it in a new Soma Stanyon frame and when I opened up the box, I found paper as you describe. Some words about professional installation but no instructiions. Tried to find my 3# copper hammer -- heavy but soft, sort of like out president, and the same color, too, but couldn't find it. Probably loaned it to may neughbor for cracking pecans. Had to resort to a funny llittle wrenchy socket sort of thing. I hope it lasts after this non-standard installation.
