Size: 30cm * 28cm * 12cm Weight: 918g Color: Black Material: PU leather This is an extra-large saddle. Standard bicycle saddles, even the wider ones, are only about 20cm wide, so you can see how wide this one is. Designed based on ergonomics, the left and right sides are curved and raised to fully envelop the buttocks, and the thick, plush cushion reduces the load on the buttocks, providing a level of comfort unlike anything you've experienced before. Two high-performance dampers on the underside reduce impact during riding, further enhancing the ride comfort. The surface uses high-quality PU leather with excellent water resistance and flexibility, so it's fine even if it gets wet in the rain. *Seat post is not included. *Cannot be used on bicycles where the saddle cannot be removed from the seat post. *Cannot be used on sports bikes, etc., where a clamp is attached to the seat post. *Installation instructions are not included. If you have no experience replacing a saddle, please take it to a bicycle shop or install it under the guidance of someone with experience. *Installation tools are not included. Please prepare your own. Clamp (yoke) inner diameter: 22mm *Can be used with seat posts where the outer diameter of the clamp mounting point is 22mm.
