Ergo-Light Stem angle options(1 post)

Ergo-Light Stem angle optionsB2
May 30, 2003 6:23 AM
I've got a Colnago Ergo-Light Stem with only one eccentric sleeve. My understanding is that this provides me with two stem angle options and that a second eccentric sleeve is furnished in some instances that provides a third stem angle option.

Well I'm trying to figure out what stem angle options I have. My head tube angle is 71.8 and when I rotate the eccentric sleeve so the stem is at the lowest angle, it's not quite level to the ground (76 degree stem maybe?). When I rotate the sleeve so that the stem angle is the greatest, the stem is just shy of being 90 degrees to the head tube (85 degree stem?).

Does any one know what the stem angles are with the two options I have? Trialtir indicates you get 80, 90 and 100 degrees, but I believe that's with a different sleeve setup (I think?). I'm definitely not getting 90 degrees with either of my options.
