The classic B17 saddle, with the addition of the pressure relieving cutout, patented by Brooks over 100 years ago. The “registered cutting”, as can be read in the 1890 catalogue, is “a sure preventive to all perineal pressure".
Ideal for long distance sports touring, trekking and atb use. It has been on the market for over 100 years, being featured in as early as the 1898 catalogue. A fine example of 'if it ain't broke, don't fix it'.
