Finally riding a big boys bike
That’s the clamp I was referencing. The fork diameter is too small for this clamp, I’ve welded on clamps before, but that won’t work with chrome plating. The stainless hose clamp doesn't look bad and it would be easier to back off for a flat repair than a seat post clamp, which is also too big. The other good thing about the hose clamp is that there would be no clamp parts to drop and loose when doing a flat fix in the field. It’s really a pretty good solution. If the band snapped then you would still have a back brake. I like this idea.
