Question for Colnago experts:(5 posts)

Question for Colnago experts:elviento
Jun 16, 2002 9:48 PM
The Colnago ergo stem has a tilting sleeve which allows either a 0 degree or a -15 degree rise. I want to know if there are sleeves on the market which will allow it to maintain the natural rise (82 deg?) and work on a 1 1/8 steerer or 1" steerer. I tried the sleeve from my ITM Millennium stem and it won't work.

Any information?

The stem that comes with Colnagos (at least the one on the C-40) is an ITM Millennium stem as far as I can tell. They just paint it black, stick Colnago decals on and charge $50 more for it. So ITM stem you have doesn't do the trick, I doubt the Colnago one will (and it only fits a 1'' steerer).

The sleeve has uneven wall thickness and allows different stem rises when installed. I just want to find one that has even wall thickness and allow the stem's natural rise.

I have owned two Colnago stems. The early model that I purchased in 2000 came with TWO bushings, a straight one and one bored at a 5 degree angle (not 15). The stem's angle is 80 degrees with the straight bushing or 75/85 degrees with the angled bushing.

The new model only has one bushing, so all you get is the 75 or 85 degree angles. I got one of the new models recently and sent it back, because I wanted the 80 degree angle. I asumed that it came with the same two bushing as the old one.

Of course the stem can also be flipped for higher rises.

If you want a straight bushing, you'll have to find someone with one of the older models to sell, or have it custom made (the pricey option).

As you found out, the sleeve is not 1-1/8" diameter like the one that comes with the Millennium. It's more like 1.180 inch as I remember. If you try to use it with a 1-1/8" steering tube, it would require a very thin sleeve (more like .025/.030 inch shim stock).
