Gilco Tubing Information?

Does anyone have any coherent information on the gilco tubing used on some colangos?

All i found is that gilberto colombo, who is designing stuff for ferrari gave the tubing it's name. Is this a high-quality columbus tubing? Or does it's optical extracvagance cover up the fact that it's just mediocre?

Thanks for any information

It's good stuff - one of the early versions of fully "shaped" tubing. Otherwise, why would Colnago have used it on their top-tier frames?

This tubing/frame does several things well:

Fast, all-day group riding where comfort/speed are issues

Sprints are a strong point- If you are riding in a group/team it works well when you stand on it- so when it is your turn to pull, this bike won't be the problem- I rode this in a training ride two days ago, and I let it have the last four miles- nice stuff

Climbing- no problem- a little flex in the bottom bracket, but maybe the rider shouldn't weigh so much!





So, the frame works for me. It is my third Colnago, and I have enjoyed all of them. Not perfect bikes though, but I don't believe it is the tubing on the Master Extra Light. Issues are paint quality related versus the Columbus Gilco tubing.

I have gilco tubing on a colnago frame i'm about to put together, and the painting is unusually simple for a colnago so i thought maybe it's lower end... Glad to see i was wrong.

Thanks for the information

Some of the early Gilco-tubed Colnago Masters had very indifferent, single color paint. I had one in light blue that looked dish-water-dull.

I have a Colnago Master Olympic that I'm about to build also along with a Guerciotti that's made out of Gilco tubing, maybe. I'm not sure if the Guerciotti is made out of Gilco tubing but it's Gilco shaped.

gilco

Interesting stuff, I have some bars that are gilco tubing (aluminum) and a Cinelli stem with Guerciotti panto, black with grooves on top with Italian colours.

While there is a possibility that the Master variants have used different tubesets depending on the era, the early ones would appear to use Columbus SL/SP as their basis. The Masters that I've seen have all used 27.2mm posts and when the Master came out, circa 1985, the only Columbus tubesets using this size of post were SL & SLX. The Colnago literature of the era specifically mentions "special ribbed Columbus SL" (i.e. SLX) for their Arabesque frameset but not on the Master, which also suggests SL. Of course, there is a possibility that it was custom drawn and that the gauges are not an exact match for SL but SL would appear to be the closest of Columbus' standard tubesets. Larger frame sizes would likely have used SP.

Edit: There's no doubt that it is the same alloy as SL, as the literature specifically mentions "chromolly", effectively ruling out the carbon-managanese Aelle tubesets and hi-tensile Zeta.
