My brooks is starting to sag. Should I turn the nose bolt or punch holes in it and lace it? It probably wasn't the best fit (for the bike it's currently on) in the first place, but it's getting noticeably less and less comfortable. I don't use a computer, but I'm sure it has a couple thousand miles. The edges are chafing my thighs as I ride and there's too much pressure on my soft tissue. I've been riding through the winter, so it's not a matter of adjusting to being back on the bike.
