The bike I have comming? The seat post is 30.4 dia. What do I do? But a smaller dia. post + shim?
They all go up and down too. I suggest they are called linkage suspension, to which there are coil spring and elastomer versions. https://www.electricbike.com/suspension-seat-posts/Got me. I meant a sest post other than one that goes up and down. I don't know to explain the Suntour kind of suspension. Back and forth?
