Make Your Ride More Enjoyable SP12 NCX Suspension Seatpost with Protective Cover

The cycle path I use in Melbourne is far from smooth and I was getting lower back pain. The shim I ordered to fit the 27.2 post to the 30.0 mm tube was the wrong size, but I was not required to pay for it and I re-ordered. So I had to wait a while to fit it. An amazingly smooth ride now. Even big bumps and dips, I don't feel. The bike does, but I don't. Never written a review before, but I felt compelled to give credit where it's due. This product does what it claims to do and is easy to fit (when you get the correct shim ,if you need one).

It is super good on Aventon Aventure 2. After I inflated from 10 to 20 PSI to increase range , the bike was too hard , kicking like a horse. I had a bad back fo a week before I installed this one in 2 minutes. It's like my 4 inch fat tire has 5 PSI pressure. So soft on humps and bumps. Expensive though !

Corresponde totalmente às inúmeras avaliações positivas (nacionais ou do site da Amazon US). Instalei-o em minha Specialized Turbo Vado 3.0 IGH e o resultado foi muito bom, mesmo porque essa bike não tem atualmente qualquer amortecimento no canote (embora imagens do manual mostrem que já teve no passado). Complementei com um selim acolchoado e o resultado final foi bastante benéfico para minha coluna e o conforto em geral, ao pedalar em piso irregular (paralelepípedo, p.ex.). O canote (original) da Suntour é um produto de excelente aparência e bem projetado, com um suave funcionamento de seu mecanismo. Acredito seja durável, seguindo-se as recomendações de manutenção do fabricante. É um produto caro, mas a transformação da bike é notável. Infelizmente, vejo que o preço atual na Amazon BR (12/02/26) excede em mais de 100% o que paguei em 31/12/25. Difícil entender por que, se se fizer a compra no site Amazon US, o custo final para entrega no Brasil ficará em torno da metade daquele anunciado no site brasileiro. Aos eventuais interessados, sugiro aguardar uma oferta razoável no Brasil, ou optar pela compra na Amazon US.

First I put one of these on my e-bike, and it made a big difference in the ride. The bike has front shocks, but I was getting hammered through my butt and my old back didn't like it at all. After some research on seat post shocks, This one seemed like a good compromise between performance and cost. It exceeded my expectations for performance, and within a week, I decided to replace the old seat shocks on both my wife's and my hybrid bikes. In both cases, the improvement was dramatic. I highly recommend these seat shocks.
