The saddle protection fits on almost every adult bicycle saddle, I think. By an adjustable elastic band, which is below the saddle, can be prevented evtuelle folds on the seat. The protection has a tight and wrinkle-free (definitely on my saddle), is impermeable to water, does not smell like plastic and is not too bulky despite the qualitativ good acting plastic. Bit expensive for a bit plastic, but I think here you pay just the name: o) Otherwise everything great, strong buy recommendation.
