Chamois cream is one of the last things cyclists talk about, but this “area” definitely needs preventative care. Get a good chamois cream and use it, on your chamois and on yourself, every time, because you don’t want to be that person wiggling and shifting on your saddle every 30 seconds on a group ride. (We’re all laughing at you.)
It seems ridiculous to pay $30 for a tiny jar (other brands) of what is essentially diaper cream. But don’t fear—there are cheaper products that are just as good—for example, Enzo’s Buttonhole Chamois Cream. More than just a clever name, Enzo’s works well and comes in massive quantities for cheap (8oz for $20!). They have a 1oz size too, which is great because TSA can’t take them from you!
