Is it me, or does it seem like there are more than usual nice eighties/nineties italian steel frames available recently?
I'm familiar with SL/SP, SLX, SPX, Alle, chromor Columbus tubing. But can anyone comment on, or review the ride quality and spec of TSX? Isn't that a more modern, updated version of SLX?

It's not you.

TSX is a similar tubeset in that both SLX and TSX are reinforced with internal helical ridges.

For a representative tubest ( 54 cm) the Columbus literature listed a TSX farme at 1945 gms, while an SLX tubeset was lsited at 1966g.

The difference beteween them is this ; the thickness of the butted sections for top and seat tube in SLX is 0.9 mm and for TSX it is 0.8 mm. Also, the TSX top tube also has the internal ridges while for SLX it does not.

That's it.

< --------------- BTW - Post #5,000.

I spend too much time here.

SLX and SPX has the helical ridges, splines like rifling in a gun barrel, in the butted areas of the 3 main tubes. TSX actually has the splines running the length of the 3 main tubes. The thought at the time was to increase rigidity. This tube set was quickly supplanted by Columbus' own EL and EL/OS tube sets, followed by Genius.

I've owned two TSX frames, one a custom Marinoni and the other was a Pinarello Gavia. I would not recommend this tubeset for those using smaller sizes, probably 54 and down. I ride a 50-51ctc and have found the tube set to be rigid and jarring. For me, it did not produce the lively ride one finds in a steel frame. This applied to both the Marinoni and the Pinarello. I sold the latter despite its rare black chrome finish. Out of the SL/SP, SLX/SPX and TSX line which are all variations on the same diameters and formulation, I like the SL the best for quality of ride.

Boneman,

Thanks for that info. Did not know the ridges ran the length of the tube in TSX. Tha t would make it harsh I would think.
