This 31.8mm black rear carrier/seatpost clamp comes with 5mm additional nodes, making it super easy to attach a rear carrier.

Using this seatpost clamp is simple. First, find the right position on your seatpost. Make sure it's a good fit for the 31.8mm size. Then, attach the rear carrier to the additional 5mm nodes. Tighten the clamp securely, but don't over - tighten as it might damage the seatpost. When it comes to maintenance, check the clamp regularly for any signs of wear and tear. If it gets dirty, you can use a mild soap and water to clean it. Keep it dry to prevent rusting. Also, if you notice any looseness, retighten the clamp promptly.
