Sorry, I don't know the answer to this.  But I have another question.  I use
low-riders, Blackburns, and have the model for braze-ons that go all the way
through the front fork tines.  In this model, there is no hoop connecting the
left and right rack;  instead, each rack has two top horizontal struts (instead
of one) that go back and straddle the tine.  There's a bolt that goes through
one strut, through the fork and out through the other side, then through the 
other strut.

I've had severe vibration problems in fast descents, despite balancing my
panniers carefully.  I wonder if it's because each pannier/rack can 
independently "lever" or twist a fork tine.  In the older style low rider
racks, the racks and fork together have their rigidity enforced by the 
connecting hoop between the left and right racks.  Thus, for example, with
this older style the two fork tines couldn't simultaneously twist outward.

I wonder if anyone knows whether this might be correct;  particularly if anyone
has tried both types of rack and found this problem with the independently
mounted halves for full braze-ons.
