DEDA Zero100 Handlebars


Maybe you've heard that carbon fiber is stronger than aluminum. But if you feel more confident with aluminum, we won't argue; we'll just show you this bar, the Deda Elementi Zero100. The Zero100 is the aluminum entry in the new Deda Rapid Hand Movement (RHM) design initiative. Deda noticed that more pro riders have been raising their saddle in relation to their bars. As a result, it seemed that riders were spending less time on their drops. So, rather than raise the bars, something a rider might be loath to do because she likes the position of the tops for climbing, they shortened both the drop and the reach of the bars. Shorter than a traditional shallow drop handlebar. The position is designed to allow for a super quick change of hand position from the tops to the drops.This bar is an iteration of RHM that appeals to traditionalists. The drop is a fairly round curve, though the radius of the curve is tighter at the top and increases as it goes down. It isn't quite a traditional even radius that you'd find on Deda's deep or shallow traditional-style drop bars, but it is still fairly round. Like all Deda road bars, the Zero100 can have aero bars mounted on the center section. Deda only recommends use of their own aero bars, but others can fit. Deda would prefer people use Deda stems with their bars, but the warranty isn't contingent on the bars and stem being from Deda. They also say that even though Deda measures clamp area of the center section of their bars as 31.7mm, it is essentially identical to other manufacturers' 31.8mm (save manufacturing tolerances). Both are 1.25", just Deda takes the metric fraction 31.75mm and rounds down, while everyone else takes the same fraction and rounds up.The Zero100 has 128mm of drop and 75mm of reach. Both are measured outside-to-outside. The bar comes in 40, 42, 44, and 46cm widths, measured outside-to-outside. The actual weight of the Deda Zero100 Alloy Handlebar: 40mm is 246g. 42mm is 254g. 44mm is 261g. 46mm is 268g.

Good overall shape.
Flats on tops of bars are at correct angle and comfortable
Continuous flat profile with SRAM shifter hoods.


High price for aluminum, though you might find them closer to $100.
A bit heavier than carbon bars.

My bike came with FSA K-Force Compact Carbon bars (209gm actual). They're 42cm center-to-center but only 40cm wide where the shifters mount, and because of a gradual bend behind the shifters, the straight part of the tops is only about 30 cm wide. This doesn't leave much room on the tops for my hands. Another issue is the flattened sections on the tops are tilted back relative to how my hands rest. The narrow tops and rearward tilt of the flats wasn't working for me.

I decided to replace them with aluminum Deda Zero100 bars (267 gm actual). These bars also measure 42cm c/c but maintain 42cm where the shifters mount and have a somewhat tighter bend behind the shifters. Together these make the straight part of the tops about 35cm wide. Also, the flats on the tops are closer to horizontal. The additional width of the tops and the angle of the flats works much better for me.

Another feature of the bars is how nicely they mate to the SRAM shifter hoods. The tops and hoods form a continuous flat profile.

You might expect aluminum bars to ride harsher than carbon, but these feel less harsh than the FSA carbon bars. Overall, I find these to be quite and improvement and am very happy I made the change.
