Pile on the comfort on all your rides by upgrading to Sunlite's awesome Backrest Saddle. It fits on standard seatposts for compatibility with most bikes. And, with its height-adjustable backrest (up to 9 inches) and 11-inch wide by 9-inch long seat, you can sit back and enjoy great support and comfort. The vinyl cushions are nicely padded so you'll float over the bumps.
