This one has been tapped to 24tpi right over the 26tpi threads. I've installed a Shimano UN55 in it with no issues. Unfortunately, I can't say anything about longevity, as I'm still hemming and hawing about getting "just the right" crankset onto this thing.



I'm really tempted just to use Raleigh's current square-taper Heron crankset, but I can't find anyone selling 'em.
