Ishiwata 024 was seamless chrome-moly tubing, slightly heavier gauge than the more common 022 tubing:

Harking back eight years, I would agree with unworthy1. Ross used 024 tubing on their top (or...nearly top if you can find the super unicorns above it) 294S Signature model, of which I have. Hand-built in PA, all that. Ride is sublime, and the bike came in at 23 lbs ready to ride (25" / 64cm frame, no less).

I found this post from T-Mar on bike-air from 2007... he says 27.0. The math doesn't make sense to me. 28.6 minus 2x.7 = 27.2, righ? https://www.bike-air.com/Help-ID-ing-..._10395024.html

How should I read this for seat post diameters? I have an 024 bike now with no post.

While the main tubes are Isiwata 024, the presence of stamped dropouts indicate that the stays and forks are almost certainly hi-tensile steel which compromises the weight, ride quality and level of the bicycle. The remaining components appear to be mostly upper entry level, with a swaged crankset, steel headset, non-micro-adjust post, etc. I'd say this bicycle was just above the cusp of entry level and mid-range during it's era.

I had a similar Ross Paragon, but it was probably a higher quality build as it had forged dropouts and the seat stay caps were nicer. https://www.bikeforums.net/classic-vi...s-paragon.html
