ITM "the stem" question(7 posts)

ITM "the stem" questionesbike
Jan 2, 2002 6:00 PM
Bicycling magazine reviewed this stem:

They state that even a scratch in the paint means the stem has to be replaced due to the problem of magnesium oxidizing. Is this true? Anyone out there actually using this stem?

I haven't used this stem, but see where even 'ol Bicycling recognizes the Ritchey WCS. I have three of these (130mm), and they are install and forget about it. I weighed one on calibrated digital scales, my mfg plant is ISO 9002, and it came in at 142 grams with all the hardware. Performance recently had this stem for ~$69. Just my opinion.

Yes, this is true. I know of one person who ruined his stem because of this. He tried to remove the decals. ITM felt sympathetic and they replaced it, but he is a pushy sort and I don't think they would do this for most people. I'm told that the stem is quite stiff, and obviously very light. I would trust it, however I would be worried if I saw a scratch.

guy I rode with had one. Said you had to be super anal with the torque wrench--and when torqued to spec, if you jumped on it, the bars would slip. Seems like a worthless piece of cr@p to me. Get the Ritchey if you are a weight weenie, otherwise get the Thomson.

The ITM Millenium is around 140 grams, actually lighter than the same size Ritchey I weighed. I have three of them, and they have worked flawlessly.

What I was told about this stem is that ITM took their CNC program that they use for aluminum and used it on magnesium. Which results in a great weight savings, but certainly isn't going to do anything for the strength. 130-140 grams seems to be about where everyone else is at with weight, so that is about what I trust. And to answer your question, magnesium does oxidize and will ruin the stem. Not sure exactly how long that would take, but it would happen. I do know someone who has been on this stem for about 6 months. He weighs 145 lbs and does long, slow rides, no sprinting. His seems fine so far.

I own one, and it did come with all kinds of nasty warnings about not scratching it. It is plenty stiff, and there is no comparison between it and even the beloved WCS in terms of weight. If you are a true weight weenie, 40g is a big deal, and that's the difference between the two.
