Back in the 1890s John Boultbee Brooks developed the first saddles featuring 3 springs, 2 at the rear and 1 at the front. The B73, introduced in the 1935 catalogue, is the only model still featuring this construction.
The B73 is about one thing: comfort. The wide base, double rails, and classical springs ensure that your ride is smooth, easy, and elegant. This particular model is ideal for more upright cycling posture, such as 'sit up and beg' bikes where the handlebars are higher than the saddle.
