FillnRide is a cutting edge bike seat cover that slips over your existing road bike type seat. You just add water and slip it over your bike seat. It's that simple! The added water is absorbed and released by the water stabilizer cubes inside. Unlike gel seat covers, FillnRide never hardens! The consistent feel is permanent and you will be riding on a cloud of pain-free pleasure. Why suffer during your rides? It can be used on any narrower road bike type seats found on  racing style bikes, exercise cycles like Peloton and Nordic Track etc. Buy it here! In Stock!
