Thats great, sorry to say I just ordered mine two weeks ago and surely paid more than $125.00 to get it directly from TrickStuff.
My question is in order to adjust the chain tension is that done with the two allen screws on the face of the BB? If so that would require you to remove the cranks in order to secure the two screws down correct?
I will have to post installation and adjustment details on the blog.
The two allen screws on the face of the EBB are only there to secure the notched plate to the disc that hold the bearings.
This is how the EBB works. Imagine a standard outboard bearing bottom bracket. It is composed of two threaded cups that thread into each side of the bottom bracket shell. Inside of each threaded cup a bearing is pressed in to support the spindle. This product is essentially the same, with one major difference. In this product, each threaded cup contains a disc. The discs are not pressed in, and are free to rotate during adjustment. Each disc has a hole bored into it, offset from the center, containing a bearing. When these discs are rotated in their cups, they throw the crank spindle backward of forward. This positioning sets the chain tension. Once in position, the discs are fixed into position by tightening six set screws located around the perimeter of the threaded cups. Not shown in the photos are the spacer rings that fit between the bearings and the inside faces of the crank arms. They fit into the large holes beneath the two screws on the face of the EBB.
Once the crank arms are on, it would be very difficult to adjust the discs, especially on the drive side with the chainring and chainring spider in the way. So, the design incorporates a large thin disc permanently screwed onto the face of each disc. This disc is wide enough to allow a person's hands to manipulate the disc position by hand, even on the drive side with the cranks attached. You simply place your thumbs and fingers into the notches on the perimeters of the discs, and turn by hand to adjust their positions. Once the chain is tensioned correctly, you tighten the set screws on the threaded cups, and the EBB is ready for use.
It does not slip. The set screws hold the discs in place very securely. The ordinary M5 set screws are easily replaced if they are ever lost or damaged.
