What our customers are saying about Bonin Seatpost

An excellent, simple, and good quality seatpost offering great value. This hard-to-find 25mm seatpost is a perfect solution for raising a children´s bike seat. Its versatile design, with a subtle matte chrome finish, also makes it ideal for adapting new saddles to retro scooters like the Ciao or Bravo Piaggio that use 22mm or 25mm sleeves. A surprisingly effective product at a low price
