that one is a pursuit frame. a 10 speed version would be called a time trial frame. they made them like that to cheat wind before they came up with aero tubing. shogun and nishiki made a bunch of them in the 80s. some have 24" front wheels, some have 26" (650c) fronts. i think the shoguns and nishikis all had 24s. familyman has a pinarello TT frame that he converted that has a 650c front, and bianchi rider on the road forums has an old school bianchi that he just got together over the weekend that also uses a 650c front. he set his up with gears though.

i have a pursuit frame with a 650c front. it's dutch. i've posted pics of it before, and it's on the fixed gear gallery (justin's van tuyl). i gotta say, it's a fun bike to ride, but risers are really the best way to go if you're riding on the street, or plan to ride for any extended period of time. it's also a lot easier to un-weight the rear to skid, so i've never put a brake on mine, and i wouldn't reccommend it to anyone unless you were using a rear brake too...i definitely wouldn't try a front brake assisted leg lock. oh no. definitely not.
