Is this a trick question?

The "old" SLX is Cyclex chromoly with internal helical reinforcement.

The "new" SLX is a complete monocoque carbon fiber frame available in small (500mm), medium (530mm), large (560mm), and extra large (590mm) frame sizes from the Columbus Carbon Lab.

Check out this post on cyclingforums.com. One of the responses to this guy's query says SLX NEW is essentially old SLX that's Nivachrom (air-hardening) instead of Cyclex like the "old" SLX. If true, that makes it more suitable to TIG welding, but it can also be used for brazed lug or fillet brazed construction.

I don't know how authoritative his response is.

It is a Coppi steel frameset that is fully lugged. Years ago I had the old SLX and just curious if there was a "real" difference.

Stan, since the decal specifically says 'Cyclex' and CrMo, I doubt that is the case. Maybe someone in the builders forum on that other site might know.

Oh well, back to the drawing board.

Although searches yield a number of queries about SLX NEW, there doesn't seem to be any credible description of exactly what it is.

I went down this road a year ago.

I talked to the nice folks at Tommasini.

They told me at the time that it was similar to SLX, yet "newly" available.

I gave up and decided to just ride the bike. :)

Similar ride characteristics to a few SLX framed bikes I own, with a slightly different personality perhaps owing to frame geo. Predictable on descents, and a reasonable climber as well. Better at speeds than many of my bikes.

Built now with 10 speed Chorus.

I remember it as being the sticker that was applied after a frame had been re-sprayed, nothing more than that.

It's perfectly possible that my memory is failing, so I wouldn't put my mortgage on it!

now I remember why I hate you! :p

go, your collection of steel steeds really makes me drool. How do you like the Tommasini compared to your De Rosas, Casati Golds, Colnagos, etc? I still want a Ne Primato and Tommasini Tecno but right now, I've been scouring the CL and eBay for a late 80s or 90s Celeste Bianchi Reparto Corse lugged frame. I want one with higher end tubing and 130mm spacing. You don't have a Bianchi do you?

Thanks.

Love the Tommasini. She's a keeper. Great all around bike, especially since I (the kids and I) did a rebuild with 10 speed Campy Chorus. It was fine before, but the Chorus kicked the whole shebang up a notch.

I've been selling down my collection all summer. I still have several bikes that are going away. I sold a very nice Bianchi Axis this spring. I think I've owned four or five Bianchis over the last 20 years. A local owner of a race shop has way too much influence over yours truly.

Got a nice Colnago or two though to sell, but no Bianchis at the moment.

Can anyone tell me the difference between "SLX" and "New SLX" tubing? Thanks.

Nothing wrong with it, as long as you aren't too fat, and don't mind a 5 to 5 1/2 pound frame. (not frame and fork)

This is what I thought.

Theory doesn't work on my Tommasini Sintesi.

The factory has already confirmed the original finish when I visited them last summer.

Is this the "Riverniciato" decal you are thinking of perhaps?
