Ironweed hooks fit perfectly on the 13mm tubing of the lovely Bobbin Birdie
Someone contacted me recently from Holland about using Ironweeds on the rear carrier of their Dutch bicycle. They were concerned the tubing on the carrier would be too large to accommodate the Ironweed top hooks.
I knew our hooks fit on the Pashley Roadster racks because customers have sent me photos. Today I borrowed a beautiful Bobbin Birdie from the Bike Library Director and they fit perfectly. However, the tubing on the Pashley and the Bobbin, while fat, is 13mm. That's 3mm thinner than the really fat Dutch racks that are 16mm. So I dug up a 16mm tube rack to test out the hooks.
I found the hooks did, in fact, go onto the super-fatty tube carrier. The hooks work because the opening is wider than the top of the arch. At the top of the hook arch the inner diameter is about 14mm. So the hooks drop onto the fatter rack just fine but there is a small gap between the carrier and the top of the hook. So I guess the take away here is that, yes, Ironweeds will work on fat tube Dutch racks.

Thanks Audrey for letting me use your Bobbin!
