Usage Tips |

• Choosing Setback: Use 0 mm setback for more upright or time‑trial/TT fitting; 20 mm setback if you need more reach or incline towards a more stretched riding position.
• Sizing Advice: Always match seatpost diameter to your frame’s seat tube size; consider getting the length that allows enough insertion for safety.
• Installation Note: Make sure clamp bolts are accessible and torque them to spec; use grease sparingly on clamp bolts to avoid creaks.
• Maintenance: Wipe off any dirt or grit that builds up around the clamp head and seat tube junction; carbon needs gentle care.
• Ride Feel: Expect improved comfort over rough roads, gravel, or pavement thanks to the carbon flex—small bumps feel more forgiving.
