Deda Kronos Due Aerobar

The Deda Kronos Due Aerobar is built for riders who need a committed, low front-end position — the kind of setup that wins time trials, not just completes them. Where the standard Kronos sits flat, the Due drops the carbon wing extensions 70mm at a 25-degree forward angle, putting you into a genuinely aggressive tuck.

The basebar is a hollow carbon wing at 42cm outside-to-outside, with internal routing channels for brake cables and electronic shift wires built in. The J-bend carbon extensions can be dialed out to 370mm of reach, with measuring lines screened directly onto the bars so you can set — and repeat — your position with precision. Extensions come plugged at both ends, but the plugs pull out if you're running mechanical or electronic bar-end shifters. Armrests lock into the bar via cylindrical housings on either side of the 31.7mm clamping section, and 25mm stack spacers are available separately if you need to bring the pads up.
