I bought a bike at a yard sale a month ago which has a nearly new brooks narrow racing saddle on it. I have never had one of these, and after three weeks of 20-miles a day, I rather like it.
What do I do with it? I presume that there is some leather goop that needs to be periodically applied. It also has a bolt in the front, running paralell with the top tube of the bike, which would seem to adjust something like the length of the seat or the surface tension or something. What does this do?
