thats a dmr locjaw which is 26.8mm and if im right so is your 24seven frame so that should fit, if not you could go on crc and get a shim size 25.4-26.8
the wheels are temp off my stinky while i am waiting to get a 24", i did it just to see if it was possible but the wheel is so close to the end of the drop out so i'm not bothering. last thing i am putting on is the new wheel because it works out like 7pounds more to buy a whole wheel rather than just hub and spokes and i cba with building a wheel
i only need a rear because the hub in my old wrecked so i sold just the rim off that which means it will cost me the same to buy a whole wheel and it saves me building. and i am getting a halo tornado but black on an ns coaster pro mk2 ss
