I am already future proofed regarding bicycle stuff. I am in my 70th year and have 8 bikes and a lot of spare parts. I could ride the rest of my life and probably not have to purchase anything other than tires, tubes, cables and other consumables. I would need very few of those, even if I reach 90 and am still cycle-active. That is a lot different than saying I will not buy anything I absolutely do not need. I have a tendency to cave on some items just because they are on sale, or because I like them. Lately, I have been struggling with wanting to purchase a pair of Giro spd shoes that are on sale at half MSRP. Really nice shoes, that I really do not need, but tell myself it is a really good deal. I already have 3 pairs of SPD shoes, 2 pairs of SPD-SL, and a pair of SPD winter cycling shoes. So, If I buy them and do not wear them, not such a good deal.
