Deda's updated Zero 100 RHM aluminum bar is a truly compact design, and features their RHM (rapid hand movement) concept. With a 75mm reach and 130mm drop, the Zero 100 has ideal dimensions and shapes for moving quickly from one hand position to another. More importantly from a user and bike fit perspective, the bar sets up perfectly with current shifter body designs to allow for better positioning and fit, while ensuring proper weight distribution over the front wheel for most cyclists. The triple-butted 7075-T6 alloy construction ensures great strength and stiffness, especially at the clamping zones, but also keeps the weight low with significant fatigue resilience. The bar shapes are generally rounded, and when wrapped the bar feels very natural in the hands. The drop itself is actually a fairly round shape at first glance, but as you look more closely, you see the increasing radius towards the top, which provides better shift/brake lever access for any size hands. There is no anatomic shaping, but the curve drop offers aggressive hand positions that are still comfortable. The ends of the drop have a slightly larger diameter, so you feel where the bar ends, and is also easier to grip when you power down in a sprint. Looks like new except that the cleaner I used to remove the residual tape goo also took off the “Zero 100” lettering. Also note that Deda measures width at the bar ends, so it will be a bit narrower at the tops.
