Great test and appreciate the work everyone at FWB puts into it. I prefer a stiff stem but I'm not sure that I can tell if any of my stems flex. I don't feel any flex, even with my 56.5 gram stem which is 105 mm. long

the test shows that the Vibe is clearly a super stiff stem. It just suffers in the S:W ratio because of the extra mass it has.

Kittel's stem is a modified Pro Vibe stem (maybe the PLT Stem with modified steerer clamp diameter) made specifically for Giant the 1-1/4" steerer with a more standard 4 bolt face plate, as opposed to the puzzle system on the standard vibe.

@madcow,

Would like to suggest a test on Ritchey C260 "Superlogic" full carbon stem.

@LouisN, thanks. No way I am going to toss it because of the test. :) But it was interesting to learn something about it. There is also nice sum up about Pro Vibe on before the test results.

I'm surprised the Deda 0-100 and Trentacinque 35 were not tested.

The Kalloy Uno 7 would also be an interesting candidate, it is so popular here that it has its own thread. I wouldn't be surprised if it tested very similar to the New Ultimate (since it looks a lot like it), it would just smash it in a stiffness/weight/price ranking :-)

Interesting note about the syntace f119 not being offered in 110mm as I have three of them as well as a few 105mm 's. ;)

This sounds like the perfect opportunity to prove - with (ostensibly) scientific objectivity - whether or not all the scare-mongering about so-called "low quality" Chinese replica carbon stems has any scientifically-proven basis.

Is there any reason why your tests don't include a single "knock-off" Chinese carbon stem? Of course, there is no inherent anti-bias against them on the tester's part! And there's certainly no conflict of interest in regard to any undisclosed relationship between an authorized dealer and the makers of some of the name-brand stems on test! Perish the thought! Right?

In my opinion, any test claiming to be 100% unbiased would be remiss if they didn't include any "placebos" in their test.

I vote for including in the next round some replica Chinese carbon stems for side-by-side comparisons to their "high-quality" name-brand counterparts.

I'll even volunteer my services to help you source some of the reverse-engineered stems:

Food for thought, the time and energy spent on this is greatly appreciated.

Lighter aluminum stems are more flexible than heavier ones. Nothing new there.

They deflect up to 5mm in your test. How is that data useful to us? Is 5mm of flex something we should care about? Does this show durability to be a concern with the lighter stems?

Makes me feel better about the ENVE stem I just purchased.

Simple really. Reverse Engineered is not what they are. Fake or knock-off, take your pick. Testing them would undermine their position as a legitimate dealer. Can you imagine the effect of an authorised dealer including fake versions of their supplier's product?

I pick "placebo". Because - like their pharmaceutical counterparts - they defy scientific explanation, but there's no denying they work just as effectively as anything you care to compare them to.
