We buy all our pulleys, pulley stock, and belts from SDP-SI. I agree the pulley stock is really expensive. At $60 for a 200mm bar I questioned if it was worth the cost to make our own hubs. Although the price drops a lot per bar the more you buy, which helps justify spending that kind of money.

I haven't put to much thought into mounting bumpers on this frame since it's just an offseason prototype, but I think what we'll do is something similar to 148's 2011 bumper system; put 1" hex standoffs in the corners and then use a uni-body bumper frame and bolt it to those hex standoffs. I'll CAD this and post a picture of it.

Here is a front view of the bumper frame and hex mount:
