Strengths: strong, lightWeaknesses: expensiveBottom Line: I've read a lot of reviews about these stems and I wish I could find the mounting instructions. Unless the instructions SPECIFICALLY tell you to lube the threads this should NEVER BE DONE! Lubing will throw off the torque, especially in the case of a delicate part like this. If I recall correctly, and I may not, since I've used ITM's and Cinelli's as well, they call for the use of spacers, although I know the torque spec. is used here.
Having said that, I always put these on following manufactures's spec's (in this case, printed on the stem itself) and have never had a problem with any stem, ever! I've had fatigue fractures after a couple of years use, and these need to be discarded, but that's to be expected after all the flexing and torsion these go through.
These are one of my favorites so far. Even though they're somewhat expensive, they're light and strong and have outlasted almost everything else, except a Cinelli, which are even more expensive. I also use the Newton bars and I like keeping the two in tandem.

Strengths: lightWeaknesses: easily crackedBottom Line: Very light alloy stem, but recently developed a crack in the steering tube
clamp. Deda said it's from overtightening
but I use a small hex and am very carefull
so as not to crack the carbon steering tube.
Not covered by warrenty. I think these super
light alloy stems are too delecate. I am
a light rider too, so little stress.

Strengths: ? I wouldn't know. The product failed.Weaknesses: I honestly beleive this to be a case of the torque specs being too high. If I had used my better judgement I would have simply used the same torque specs as most other stems I have used. But what I just followed the manufacturers reccomendation.Bottom Line: I went about installing the stem. I greased the bolt threads and tightened bolts using a torque wrench in an X pattern. Never got a chance to ride with the stem though as the bolts cored out the threads of the stem.
Favorite Ride: around Crystal Lake in Frankfort, MI

Bike Setup: Riding a storck absolutist 0.9. Well now I'm using an old specialized stem from a tarmac I have. Think I'll get a 3T stem. Good product, and not overpriced like so much crap that's being marketed as high tech. A stem is a stem. It just needs to be relatively stiff and strong.

Strengths: 4 degree angle is less steep then usual 6 or 8 degree so you need fewer spacers flipped down and if flipped up it looks better in +4 position compared to +6 or +8 stems.Weaknesses: price is very high for a small aluminium part. alloy is not rocket science! hence average 3/5 value rating.Bottom Line: this is review for Newton 31-86 stem, i.e. 4 degrees not the Newton 8 degree. i have 3 of these: 100mm, 110mm and 120mm for different bikes. great stem, excellent angles, compatible with non-Deda 31.8mm O/S bars. i dont know why others dont make +-4 degree stems, they are perfect for less flexible riders who may find 6 and 8 degree stems too steep.

Strengths: Light. Been reliable for me.Weaknesses: None that I have found.Bottom Line: I have used the Newton Stems since they have come out and never bothered to read the reviews until today and was surprised. I am 6'1" and 200+ sprinter/TT sorta racer. I have never experienced the problems mentioned and have four of the stems in various lengths and ages that get swapped around a bit.
I do grease the threads when first out of the box and am careful with getting the bolt tension even, although I use feeler gauges to set even spacing as my torque wrenchs are for bigger stuff.
Favorite Ride: All and except cold rain
Price Paid:
$1.00
Purchased At: Two Wheel Transit
Similar Products Used: Think of a high quality stem over the last 35 years and I have used it.
Bike Setup: Very nice.
