The B17 Narrow Imperial is another variation of our time-honoured B17 design, featuring a distinctive cut-out section in the top of the leather, first conceived and registered by Brooks over a century ago. In the catalogue of J.B. Brooks & Co. dated 1890 a model called the B86 Imperial, with its unique "registered cutting", is described as "a sure preventative to all perenial pressure". Another distinctive feature of the B17 Narrow Imperial are the perforations along the lower edge of the leather sides, which are threaded together one side to the other by a lace. This can be adjusted to help maintain the saddle’s shape and provide comfort in the long term. Tying the leather lace tightly pulls the sides of the saddle closer together, conversely loosening the lace enables the saddle sides to splay slightly further apart. This sideways fine-tuning of the B17 Narrow Imperial is of course in addition to the usual fore-and-aft tensioning mechanism common to all Brooks Saddles.

MADE IN ENGLAND

Brooks England is a bicycle saddle manufacturer in Smethwick, Birmingham, England. It has been making leather bicycle saddles since 1866, when it was founded in Hockley, Birmingham. In 2000, Brooks' parent company, Sturmey Archer collapsed, but Selle Royal of Italy bought Brooks in 2002.

Popular Brooks saddles include the B17 (fairly wide), Team Professional (narrower), Swift and Swallow (narrowest). All are available with steel or titanium rails. More niche products include sprung saddles and four-rail designs (which require an adaptor for modern seatposts).

The fundamental design of a Brooks saddle is a leather top stretched between a metal "cantle plate" at the rear and a nose piece, to which it is attached with steel or copper rivets. Using a threaded bolt, the nose piece can be moved forward independently of the rails, tensioning the leather. It is important not to over-tension the leather or it may tear, especially at the rivets. Normally the nose bolt should not be adjusted unless the saddle becomes noticeably sagged, in which case it should only be adjusted in fractions of a turn until the top is comfortable again.

After a certain period of use, which can be from 100 miles to 1,000 miles depending on the leather used to make the top, the saddle visibly moulds itself to the rider and "dimples" appear where the "sit bones" normally rest. This is caused by fibres in the leather breaking down under the weight of the rider. The saddle is normally more comfortable by this stage, although some riders find that no break-in period is necessary for comfort and other riders never find a Brooks saddle comfortable, even after many thousands of miles.

Leather saddles are not waterproof (although this does mean they are able to absorb and dissipate sweat by "breathing"). Brooks produce a wax dressing, Proofide, which should be applied occasionally. Various amusing urban legends exist about the composition of Proofide (such as it being made from the fat of hanged men) but the main component is tallow. The current blend also includes some citronella oil, identifiable by its sharp odour.
