Getting narrower at the hoods without giving up control in the drops is the trick modern aero bars are trying to pull off, and the Ritchey Superlogic Streem handles it with a shape that flares outward as it drops. The aerodynamic top section subtly sweeps 5 degrees to meet the narrower hood width before meeting a 10° drop flare that extends the bar's total width in the drops by 2cm on each side and provides critical stability for cornering and diving into curves. That means you can run a 38cm hood width for a tucked, aero position on the flats and still have a 42cm platform to brace against when you're sprinting or descending.

The wing-shaped top section measures 43.5 x 16mm and complies with UCI regulations , so this bar is race-legal for riders working within sanctioned events. The aero profile is wide and flat enough to give your hands a comfortable resting surface on long tempo efforts, but Ritchey kept the section sized to accept standard bar tape without the wrap splitting or peeling loose over time. If you'd rather leave the tops bare to preserve every last watt of aero benefit, that's an option too.

Cable routing is where the Streem earns its keep on modern builds. The bar offers full internal cable routing from the levers to the headtube, or partial internal cable routing from the levers to the center section of the handlebar. That flexibility means it'll work on a fully integrated cockpit setup or on an older frame that still runs external housing along the down tube. It's also compatible with the Shimano EW-RS910 bar-end Di2 junction box , though wider cable housing may interfere with the internal routing paths.... Read More
