Yeah it’s dumb. I bought my used mountain bike from a entusiaist. The bike was in really good shape with some of the best components money could buy at the time. Out of curiosity i asked him why he would sell the bike. He said he really liked it a lot, but it was just too heavy for long uphill rides. He then showed me the bike he replaced it with. A brand spanking new high end mountain bike. When i was home, i just had to know and compared the specs roughly from what i knew. My calculations said that his new bike was like 50 to 100gramms lighter. The guy wasn’t really a featherweight either. Eating less would’ve saved him like 5k
