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

 

[Scooper]

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.

Scooper, there is also a steel tubing labeled 'SLX New' (picture from Italian Cycling Journal):

I have never heard a definitive answer as to what it is.

Ahh. Thanks for that. I like to think I keep my ear to the ground, but I'd never heard of a new SLX tube set. I've got some homework to do now.

Here's the SLX carbon frame:

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.

 

[Scooper]

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.

If I remember correctly, the SLX New was originally called PRX.

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.

 

[Unica]

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!

 

[Ride-Fly]

now I remember why I hate you!

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.

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)

I think you are about a pound high there.

....and right you are sir!

Mr. G though has me a little worried about the weight. Time to drop a fast 10 pounds before they tie a string around my foot and use me as a float at the Macy's Day parade.

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?
