Handlebar selection comes down to fit, and the Service Course SL-70 gives you a shape that works for riders who prefer a compact bend without an aggressive drop. Zipp designed this bar around an ergonomic top section that sweeps back four degrees, which positions your hands naturally during long efforts on the hoods or tops. The 70mm reach and 128mm drop put you in a moderate position—aggressive enough for spirited riding, comfortable enough for all-day events.

The aluminum construction uses 6061 alloy with double-butted walls, which removes material from low-stress areas while maintaining thickness where loads concentrate. That butting process is how Zipp keeps the claimed weight competitive with bars costing significantly more. The 31.8mm clamp diameter fits standard oversized stems, and the clamping area uses a pointed diamond knurl pattern that grips stem faces without requiring excessive bolt torque.

Internal cable routing keeps housing hidden on builds where aesthetics matter. The entry ports sit on the upper flat section, and the routing maintains smooth curves that won't bind shift or brake cables. If you're running mechanical groupsets, the clean appearance approaches what you'd get from an integrated cockpit at a fraction of the cost and complexity.... Read More
