The tubing is probably a bit higher grade than the bike. Ishiwata 024 was a bit heavier than the 019 and 022 that went into many very nice bikes, including such as: San Rensho, Trek, Bianchi and some Ross bikes that sold for more than this one. I figure 024 as being akin to Columbus SP or a Touring set of 531, it's gonna be plenty strong but a little...heavy...probably not something you'd notice in the ride. This looks like a mid-grade Ross, likely made in Japan rather than Allentown, PA...it's got stamped rear DOs, that weird ""safety-C" fork end, and probably .833 size stem...fix it up and ride it!

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).

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

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

Your math is good but you now want to subtract .2 from 27.2 so the seatpost will have just a little extra room to allow it to slide in and out.

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

Sorry @T-Mar and @nikkorod to be confusing. This is a zombie thread but I replied to it because JohnDThompson posted the tubing specs. The Paragon that I picked up also has forged drops. I don't know if the one in this thread's OP is a Paragon.

Thank you for the explanation.

My 1982 Ross Super Gran Tour XV has the heavy duty touring spec I****awa 024 tubing. It was their top quality (and price) calalog model with the exception of the hand built "Signatures." It is a fabulous 15-speed ride. Just my opinion.
