Brooks England: B66, Brown

The B66 and B66 S are among BROOKS’s most loved products, having been on the market since 1927. Classically sprung with double rails for supreme comfort, B66 and B66 S are 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.

Brooks England: Cambium C15 Carved, Slate

The Cambium C15 Carved shares the same narrower shape as the existing Cambium C15, but with an ergonomic cut-out to provide relief from discomfort in the perineal area, experienced by some cyclists.
This “registered cutting, a sure preventive to all perenial pressure” is also to be found in the saddles of the Brooks Imperial line.
Made from vulcanised natural rubber and organic cotton top, combined with a die-cast aluminium structure and tubular steel rails. For performance, a distinct dampening effect is delivered by the classic Brooks “hammock” construction keeping the rider in unparalleled comfort mile after mile.
