The B17 is Brooks's flagship model, with over a 100 year heritage. Great for the daily commute, it's also ideal for long distance sports touring, trekking and even mtb use. The model is available in two lengths: the B17 and B17 S (shorter, sometimes preferred by women). The Standard models feature steel rails, whilst at additional cost the B17 Special features copper plated steel metalwork, and stunning hand hammered copper rivets.Many find a Brooks comfortable from the get go, however as with a horseriding saddle, it will 'break in' as it conforms to your personal shape. As the weeks tick by, it's feel will improve accordingly.
