Historically, Brooks Saddles were made with small rivets. Racers in the continental tours would have their Brooks Saddles re-finished with larger copper rivets to increase longevity, as they are gentler on the leather top. This practice was adopted by Brooks decades ago. A single badly-aimed hammer blow can irreparably damage the leather, so the utmost care must be taken during manufacture. Each copper rivet on all Special saddle models is carefully hand hammered by skilled craftsmen.
