The first Brooks I had, ( after I wore out my expensive saddle , which I'd saved up what was a fortune to me in the 70's to buy, on a summer long trip across Europe) was already about 20 years old when my great uncle gave it to me. I still have it, and the only reason I'm not using it, is because on a modern seat post, it won't sit level. I also have an engraved leather, lovely women's sprung saddle which belonged to my great aunt and must be at least 60 years old, probably more. it is now fitted on an old French Terrot women's bicycle that I rescued from a skip. However, that has not seen the use that my great uncle's has. It must have done many thousands of miles. He had done that thing of threading holes on each side so it could be laced if it sagged, although I've never done this. Over the last 15 years I have acquired 3 others, 2 second hand, for each of my other bikes. I don't expect to have to buy any more saddles ever, now. I'll feel cheated if any of them fail.
