The folks at 3T claim the Ergosum Pro handlebar is "shallower than traditional drop bars, with a little more reach". That statement rings true and is exactly the way we would describe the bar. It is also the reason the bar is so popular. When you think it through, being in the drops isn't always the most comfortable place, so by effectively having a shallow drop it makes this position easier to access and generally more comfortable, by being easier on your back and neck. Further, if you are going to be in the drops, why not be a bit more forward for improved position and aerodynamics - hence the "little more reach" statement.
Since this is a Pro level product it is a perfect balance of value and performance. The bars are composed of triple butted 7050 aluminum that has been shot peened and anodized black Simple but effective white-sash graphics on black bars look great and signifies the bars as a 3T Pro level product.
It's important to note that the bars are measured center to center at the ends of the bar. Each end flares out by slightly less than one centimeter each. This effectively means that the bars are slightly narrower at the hoods. The Ergosum is available in 40cm-44cm widths and offered in 31.8mm bar clamp diameter only.
These bars are flexy however I am not sure it is a bad thing. When in the drops you can see the bar move about 1/4 inch up and down. It actually seems to absorb road shock and road buzz. Vertically compliant but laterally stiff might be the way to think about these bars.
Pros: Good shape
Noticeable flex in the drops? LOL. More internet BS being ladeled out. Cancellara uses the exact version of this bar without flex issues. Enough said. Great bar.
Pros: Great bar.
Cons: Internet BS artists who claim they are flexing it.
This is the best bar I have used. If you like a compact style bar, these are hard to beat. Tops are flat, integration with STI makes Shimano levers much more comfortable than on other bars, oversized diameter feels nice in hands, levers are easy to reach, graphics make alignment easy.....
Ive searched for a long time for comfortable handlebars and these are the ones I decided on. I am perfectly happy with them. They are stiff and light and riding in the drops is very comfortable. These are way better than any of the "ergo" handlebars I tried where the ergo part was to small and my hands would get crushed into the tight bends. The long radius bend on the drops is great. I own two pairs, one on my training/racing rig and one on my long ride/climbing bike (Cdale Super Six).
I like the short reach & shallow drop, as well as the style. They are very comfortable. There is, however, noticable flex when in the drops. If you dont ride in the drops much, then I recommend them. I would buy them again.
