Light weight, comfort, and strength: the new SL-70 Ergo is the ultimate handlebar for long days in the saddle. The SL-70 Ergo combines the flat bar top shape of the beloved Contour SL bar with numerous modern features sought after by riders and pro bike fitters. The SL-70 Ergo sports a 70mm reach and 128mm drop. The short 70mm reach has been a popular choice in recent years, as it 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. - Updated distinctive Zipp cosmetics - Unidirectional carbon built for stiffness, comfort, and light weight - Flattened top shape with 3° backsweep for comfort - Variable radius drop for multiple hand positions and deeper movement into the drop. - Lifetime warranty

Wolf Tooth was first to market with cyclocross 1x specific chainrings because we saw cyclocross as the perfect use for our patent pending Drop-Stop® technology. These beautifully machined 110 BCD asymmetric 4-bolt chainrings are optimized for your 1x Shimano CX / road / gravel drivetrain whether you run Dura Ace 9000, Ultegra 6800, 105 5800, or Tiagra 4700. They are also offset for the ideal 1x chainline. - Fits 110 BCD Asymmetric 4-bolt Shimano cranks - Drop-Stop technology. On Wolf Tooth's patented wide/narrow chainring, the wide side of the tooth has maximum contact on the drive side which spreads the load and improves chainring life. The narrow side allows clearance for mud and debris which reduces friction. - Alternating wide/narrow tooth pattern prevents chain derailment Compatibility: - Fits 110 BCD asymmetric 4-bolt cranks - All sizes compatible with Dura Ace 9000, Ultegra 6800, 105 5800, RS510, Tiagra 4700 or 4703, Sora R3000 or R3030, and Claris R2000 or R2030 cranks. - 38-50t are compatible with 105 R7000, Ultegra R8000, and Dura-Ace R9100.
