The Buttero Leather Seat this is one of our Leather Seat Series. Handmade of precision and love for the detail. So 9 two-colored rivets hold the leather on the matte black powder coated steel base. Two colossal springs ensure a comfy and ass protected ride – even on long journeys. We located the spring far out of the seat to assure a low assembly on you frame. For the easy installation all you need to install the seat comes already with it. The two rails ensure you to use it with old saddle clamps or modern seatposts. The front screw ensures that the leather even after years can be re-adjusted so it fits perfectly and two saddle hooks at the back can be use for any kind of small luggage you want to take on your ride.
