![]() Rather than use a long stem and a handlebar with a relatively short reach and shallow drop (as is common even in the pro ranks), the ABB instead uses a stubby 70 mm-long stem with the rest of the length incorporated into the radically-shaped bar. ![]() While the ABB doesn’t look especially radical at some angles, a head-on shot (with the rest of the bike providing some spatial context) reveals just how unusual it is. Going along with that, it’s also been understood for some time now that you’re most aerodynamic position on a road bike with your arms outstretched, your forearms level to the ground, your back long and low, and your palms out on the lever hoods - not down in the drops.ĭutch aero specialist Speeco has taken that idea to the next level with its new ABB (Aero Breakway Bar) integrated one-piece carbon fiber handlebar and stem, working together with former Roompot-Charles pro rider Jan-Willem van Schip (now with UCI Continental team BEAT Cycling Club), who previously used to run 32 cm-wide Japanese track handlebars that bested Hansen’s setup by another 4 cm. It’s long been known that a narrower handlebar can pay big dividends in terms of aerodynamic efficiency, especially in situations where you’ve got a single rider doing most of the work cutting through the wind. ![]() Heading out the door?
