Introduced in 1935, the B73 at first glance looks like the B66, with the difference that the B73 is designed with an additional spiral spring in the front, thus allowing more lateral motion while cycling. This saddle is the end result of the development that John Boultbee Brooks initiated in the 1890's, when the first saddles with extra springs were first designed and crafted. The development resulted in this sturdy saddle, that has proven that sturdiness can very well go together with comfort and eye-catching beauty
