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

Zipp's 3ZERO MOTO carbon 27.5 and 29 enduro/trail wheelset is inspired by moto to provide riders with the control and durability required for pure trail speed. Already this wheelset and its MOTO Technology are proven with multiple victories in the Enduro World Series with our pioneering partnership with Lapierre Zipp Collective. While other wheel brands limit their focus to traditional box-section rim designs, Zipp engineers-uninhibited by legacy technology-took a different approach. They looked to motorsports as a model. Zipp's Moto Technology's single-wall rim is the optimal approach for an enduro/trail wheelset. The resulting rim provides something we call "ankle compliance." Imagine a runner rounding a sharp turn, the ankle naturally flexing to maintain grip as the runner leans.

Zipp's 303 Firecrest Tubeless wheels are designed for the real world—a world of imperfect conditions, varying road surfaces, and elements where the bottom line is simple: efficiency = speed. They're faster, lighter, and more capable over varied terrain—whether the surface is pavement in all its conditions or no pavement at all. Deeply rooted in Zipp's drive to conquer the Spring Classics, the new 303 Firecrest is remade with a purpose-made approach for the demands of modern road bikes. When it comes to going fast on a bicycle, efficiency means reduced wind resistance, rolling resistance, rider fatigue, and weight. The 303 Firecrest Tubeless Disc-brake was designed using real-world direct measurements (vs. primarily wind tunnel or computer simulation). The results were huge. Its rim is slightly more bulbous in design than its predecessor, with a 32mm outside width, a 25mm internal width, and a 40mm rim depth. The profile provides low drag and an improved transition between rim and tire, boosting aero efficiency on the road. The wide rim stance also features less tire deflection for reduced rolling resistance. The combination of the wider tire, increased tire volume, and lower tire pressure helps to reduce rider fatigue by smoothing out the ride over imperfect pavement and road conditions—the tire and wheel system absorbs the shaking, not the rider. At the center of the 303 Firecrest Tubeless is a versatile and durable new hubset, the German-engineered ZR1 DB. This hubset features 66 points of engagement for quicker response.
