The seatpost offers good comfort with precise adjustment. Good description is. One should still know that the rest about every 500 km will be built by just explained, so that they cleanse the inside and re-greasy. For this purpose a special grease is required. The specified from Suntour is not going to get through Amazon.com. Property me a comparable elsewhere worried. The seatpost is recommended if you bring some technical skill. Otherwise, I would buy them in stores, for future service.
