The B66 S is among BROOKS’s most loved products, having been on the market since 1927. Classically sprung with double rails for supreme comfort, B66 S is the ideal all-rounders for daily city or touring use in a rather upright posture. They are most appropriate for cyclists who set their handlebars higher than their saddles. In general, the more upright your riding posture, the wider, and more heavily sprung, the saddle you should choose. The B66 S is shorter than 20mm compared to B66, therefore suitable for a female users.
