KS EXAFORM DROPPER POST 30.9 100mm SPEED UP HYDRO BLACK

This dropper unit is solid and worth every penny. It was an economical upgrade for an older trail bike but keep in mind you won't be using this in advanced mtb courses. This offers a very practical solution to adjust your saddle height on the go without spending a lot of cash. As expected you can tilt the saddle to suit your frame geometry. I got the 30.9x100mm unit. Highly recommended product.

Works great , will buy again

Great for mtb noob
