Fork/steerer, wheel and frame flex may be your problem.

Pro riders are a bad reference since they use whatever their mechanic puts on their bike. Their bikes are trade tools, not passions.

I like my Deda Newton setup. I definitely feel steerer flex more than bar/stem flex. I'm also now using a Ritchey Pro 4axis and a 3T rotundo Pro on another bike. Feels rock solid. If you went with the WCS 4axis the total weight would be pretty respectable for aluminium and will definitely leave your frame, fork and wheels as weak points in the stiffness game (assuming you've gone for 42cm bars, otherwise get narrower bars for sprinting. Also assuming you're using <120mm stem).

I just went through this whole process for an ongoing build. I am 90kg, not as young as I used to be but still a decent sprinter, crit rider.

I had it down to 3 options,
The Deda 35 set with Alu bars. I have big hands and like the drop and bend on these.
The Ritchey C260 superlogic which is probably my favorite stem in theory (despite what someone said earlier is full carbon) and matching superlogic bars which aren't out yet.
In the end I went with the Zipp SC SL beyond black stem and Vukasprints because I am building a foil and wanted to complete the aero theme while still building a stiff front end.

I ride the 3T Arx Team stem and ergonovas and find them to be fairly stiff though I do feel the bars flex a little on the ends (which is good), I find they aren't bad when I move my hands up into the drops for the sprint. Super comfy bars overall though.

Someone put an excellent post earlier about the width of bars and depth of drop making more difference for stiffness, but I will add that I find the leverage difference when I go from 42 to 44 to be significant. Similar when I go to a longer stem the leverage seems to help. It may flex more but I feel like it lets me transfer more power to from the upper body to the wheels with the increased leverage. I am not sure how much the fact that I am 6'3" has to do with that. May be part of why the pros often run such long stems (other than there ability to maintain positions I can only dream of)

leverage and bar width are complete red herrings. If it mattered you wouldn't see track sprinters on 36cm bars. Sure, that helps with aerodynamics, but if they lost power/leverage they probably wouldn't do it. If you're riding hard enough to need to really enlist your upper body on a climb or in another situation you're likely to pop soon anyways IMO.

I was really talking about in the sprint and what my subjective experience was when going up in size in bars. I am likely to pop on the climb anyways.
There are other reasons wide bars aren't good on the track and flex certainly is more of an issue in a track sprinter which is a completely different breed of cyclist compared to just about every other one. I certainly am not going to flex a bar like Bauge.

Speaking of 'the latest', I hereby present the new 3T arx:



although I am not quite sure if this is mentioned before in this thread as I am new here..

Is the only difference a single bolt instead of two?

http://www.3tcycling.com/news/crisp-sub ... lassic-arx

There you go.

Looks like a Ritchey. I have an Extralite, I like the hidden bolts and the clean aesthetics.

But a Torx head bolt? I am sure well can all deal with that with our light compact multitools (sarcasm intended).

UGH!!! When is that new 3T stem coming out. I will need to stock up on the existing ones.

Thankfully, I believe they are continuing production of the old line as well.

My stems (both 26 mm, both Al):

Performance Forte with Ti bolts from Toronto Cycles: very light, rock solid
ExtraLite: bolt adjustment difficult, but extremely light and looks good

I'm running the former right now because it's 7 deg instead of 8 deg and that gives me a bit more comfort.

No stem will ever make a difference to any aspect of performance (so long as it fits).

So my 3T ARX LTD is already outdated after 2 weeks... Grrrrr
