Blackburn racks. EX-1 for the rear. FL-1 lowrider for the front. $80 for both racks.
Western Bike Works says low rider is out of stock. Is Blackburn still making front racks? I thought Blackburn discontinued them under new ownership.
As to load carrying capacity, I found Blackburn racks fine, particularly if used the Expedition rack , stoutest of the three rear racks they used to make, and used the hoop front rack or the hoopless to fork braze-ons. I have heard of Blackburn racks breaking, but that's more strain I ever put on them. I switched to Tubus racks when I bought Ortlieb bags; the Ortblieb bags fit better on the Tubus racks.
