How tight should the QR clamp be?

The QR lever should close with moderate thumb pressure — firm but not requiring full hand grip. If the lever closes too easily, the post may slip. If it requires excessive force to close, back off the tension nut. Adjust the tension nut (opposite end to lever) to find the right resistance.

Can I use this clamp on a carbon fibre seatpost?

Yes — use with the correct diameter. Apply carbon assembly paste to the seatpost instead of anti-seize to prevent slipping at lower clamp torque (carbon requires lower clamping forces than aluminium or steel).
