Cool, although these look like they need the double U-clamps, like the BMXs have? The ones I remember would have fitted standard modern-type mountain bike clamps - at least I think....https://pitbikeparts.co.uk/product/heavy-duty-black-steel-pit-bike-handlebars-740mm-wide-5-rise/I just a set of these pit bike steel bars. 5" rise. Really nice size and shape.
Shame they're in USA, postage is nearly the price of the bars...Ahh... like these Schwinn bars on ebay or the Surly Sunrise bars.
