On today's road bikes, silver stands out amid the sea of stealthy black color schemes. This time-honored seatpost color is available on the Zipp Service Course Seatpost. Since the introduction of our line of Service Course and Service Course SL components, we've had amazing success with our pro-level athletes in all disciplines. While the successes have reinforced our design decisions, we have also drawn from their feedback. We not only learned how and why athletes make their equipment choices, but how our manufacturing methods and materials affect product performance. With new knowledge as well as new engineering, we are proud to offer redesigned Service Course seatposts. - Material: 6061 aluminum - 2-bolt adjustability - Minimum insertion length: 90mm

The Spyre is a mechanical disc brake that offers superior performance with incredibly easy setup. This is a dual-piston-actuated mechanical disc brake caliper that provides precise clamping force. This translates into even pad and rotor wear, because the rotor does not need to flex to one side during braking. We added a simple cable barrel adjuster to make fine-tuning easy. All of this in an incredibly thin 40mm, 146g package that works with any drop bar levers on the market. Rotors and adapters are sold separately. For tandem bikes, we recommend the Spyre caliper paired with our 2.3mm thick rotors. This will give optimum stopping performance for you and your partner.
