Wald basket attached to Nitto rack
The strongest "alternative" Wald rack attachment system I've seen. I dislike the attachment hardware that Wald provides, which forces the rack to sit high up, just below the handlebars. Rivendell suggests mounting Wald baskets directly to a solid rack using nylon zip ties. This places the rack lower, which results in a lower center of gravity and more stable ride. But in my experience, zip ties fatigue and snap after a while. This is stainless steel multi-strand wire rated to 50lb tensile strength. With 100+ loops holding the rack at 14 points, there's greater chance of the rack itself disintegrating before the attachment method fails.
