Deda Newton Stem Failures(10 posts)

Deda Newton Stem FailuresJim Harper
Feb 8, 2002 5:51 AM
Has Deda solved the problems of the past with their Newton stems? I am thinking about buying a Newton stem and bar combo, but I have read of so many problems they had with their stems about a year or two ago I'm concerned. Is it still a legitimate concern of have they solved the faceplate problem. Also, is there still a problem with their Ti bolts stripping, my buddy said when you torque on the Ti bolts you need to do it extremely carefully or you will strip them out?

I have been running the Newton 26.0 and 215 bar combo for about 6 months now. No problems. I like it alot and would recommend it. I actually replaced a Cinelli Solido stem/ bar combo with the Deda setup and like it better. I was somewhat careful on the install but nothing extraordinary was done to prevent a disaster. The new faceplates are thicker and a bit more rounded on the corners to reduce stress risers. Bolts are the highest grade Ti with rolled threads. If anything will strip, it will be the Aluminum from the stem. This problem is just as likely to occur on any lightweight aluminum stem with Ti or steel bolts. Those bolts don't need to be as tight as most people seem to think.

Go for it.
May I ask what you like better about the Deda setup...Cima Coppi

Mainly it is aesthetics with some technical issues. I do think the quality of the stem is a bit better on the Deda. This is most noticible in the steerer clamp area. I like that the bolts(non head side) are hidden. It is also beafier (more material) at this clamp too. The Cinelli actually touches together around the steerer. I always thought this area was cheap looking and feeling on the Cinelli. I have the Deda 2002 version which has improved graphics (red and silver print) This is a minor point, but does allow you to flip for positive rise.

The extra flex comes from the 215 bar. Bend is not noticably different than the Cinelli. I do think the added flex is more comfortable but still gives confidence in climbing and sprinting. I'm a light guy at 150lbs. so I can get away with the added flex. A team mate of mine uses the 31.8 setup and likes the added stiffness. His specialty is field sprinting.

Do you put any locktite on the Ti bolts before you screw them down, I have heard of guys doing this.? Thanks
no, here is what I dotcr01

tons of grease on the bolts. You can opt for Ti anti seize, but good grease will be fine. Get grease on both sides of the washers.

My team mate who uses the 31.8 Newton setup travels for races a ton( on airplanes) and does disassembly each time and has never had one problem with the bolts or stem. This has been for 1 1/2 years. He just keeps them greased and is careful not to over tighten.
Quite the opposite, actually...Cima Coppi

I put Anti-Sieze on the Ti bolts of my Solido stem, and I have yet to have a problem with the bolts loosening.

anti seize is great if you have some around. That stuff can get messy. I just wanted to say that grease will work too. I have not had a loosening problem on the Deda or when I had the Solido. If you know anyone who wants a slightly used Solido 26.0/ 120mm for 40 bucks, let me know.
Funny you mention it...Cima Coppi

I have been waiting to buy my next solido stem for my CX bike, and the 120mm is the one I need.

E-mail me off-line at jzook@attbi.com, and let's talk. I'll get my e-mail tonight when I get home, so if I do not respond right away, this is why.

Thanks
