Trusting your life to some random aliexpress seller pushing 800g frames is a gamble i don't feel comfortable taking. Imagine it breaks from under you. While you heal from your wounds and remortgage your house to pay for the medical bills, you're like "maybe i should have bought a frame that was 100g heavier, maybe it wouldn't have snapped".
Then again, i'm over 80kg, so i'm not the target audience.
But it's still scary to me. You just dont know who you're buying from.

Thanks for this detailed input, Serge — your take adds a lot of nuance and clarity to the discussion.

You’re absolutely right to draw the line between ultra-light, high-performance, race-day-only frames and the kind of dependable bikes most of us want to ride daily without a second thought. That distinction often gets blurred, especially when people chase weight savings without fully appreciating the compromises that come with it. The comparison to F1 cars is a good one — cutting-edge, but not necessarily built for longevity or the wear and tear of everyday use.

Also appreciate you highlighting the insider view on S-Works and previous Pinarello practices. It’s easy to get dazzled by the marketing and pro endorsements, but reliability often takes a back seat in that world — literally, in some cases, judging by the stories of cracked frames in car trunks.

Unfortunately, I am a bit of a weight weenie myself — however, I don’t sacrifice performance or reliability in pursuit of lower grams. There’s a line, and I do my best to stay on the right side of it.

Your point about friends and trust hit home, too. Ultimately, a frame isn’t just carbon and resin — it represents confidence, responsibility, and safety for the people we ride with.
