^ oh, got it. the geometry and tube diameters looked similar, but looking closer at the wishboned seat stays, the difference is clear.

those old 1" head tubes are a problem. when i was toying with the idea of turning my old raleigh back into a proper off-road hard tail, i did find that white brothers still makes a good suspension fork with 1" steerers for old-fashioned 1" threadless headsets, but the problem is that they retail for ~800 bucks, and i wasn't about to throw an $800 fork on a 15 year old mid level MTB. so my raleigh lives on as my winter/back-up commuter.
