Saw this tucked away on eBay

Unfortunately, too far from mine and I don't have any 36h hubs.
But might suit someone looking to build a bombproof 29+ wheel set.
Some people advise 'wide-flanges'
Those are intended for unicycles, but I guess there's no reason you couldn't use them on a bike. Likely to be heavy.
Aye, I googled them and they're well respected rims for large riders if you know what you're doing, wheel-building wise.
Weight isn't too far off the surly rabbit holes.
I'd have snapped them up, were it not for the 500 mile round-trip!
I have a rear wheel laced to one of these rims - its been indestructible over 4 years of abuse - when i bought it it was the only alternative to a rabbit hole ( a lot cheaper to ) buy wth confidence
