Zipp SL-70 Aero Handlebar

Zipp SL-70 Ergo Handlebar
$275.00 - $329.99
Light weight, comfort, and strength: The SL-70 Ergo is the ultimate handlebar for long days in the saddle. The SL-70 Ergo improves upon the flat bar top shape of its carbon predecessor, the Contour SL bar, but also with numerous modern features sought after by riders and pro bike fitters. The SL-70 Ergo sports a 70mm reach and 128 drop. The short 70mm reach allows bike fitters flexibility in achieving a comfortable position without sacrificing steering control. The drop utilizes a variable radius, allowing for multiple hand positions and deeper movement into the drop. As a result, reach to the brake lever is shorter. A 3° backsweep on the flat tops keeps the wrist in a comfortable position, essential for long days on pavement or gravel, while the 10° ramp angle provides a smooth transition to modern shifter hoods. Brake and shifter housing is elegantly hidden along the underside of the bar. The SL-70 Ergo weighs only 205g but is strong and durable enough for the demands of aggressive cyclocross and gravel racing. - Unidirectional Carbon built for stiffness, comfort and light weight - Ergonomic top for all-day comfort - Variable radius drop for multiple hand positions and deeper movement into the drop. - 70mm reach - 128mm drop - Variable radius drop - Cable grooves
