Reddit take

Not enough linked mention summaries yet; the source excerpts below are the evidence.

Pros

  • AXS and Di2 are both good enough for the pros.
  • Di2 is a nice upgrade over mechanical shifting.
  • I folded immediately after the test ride and bought the Di2 option. Felt awesome
  • I have Di2 and would thoroughly recommend.
  • Di2 is unreal. I was sceptical about electrical shifting before test riding a bike with one, now I wouldn't buy another bike without Di2.

Cons

  • Trace Velo is really good for good quality/value Chinese products and escaping the S-Works, Di2, Cosmic Ultimate Pro EXP galactic train of overpriced/overhyped
  • I prefer the SRAM app and shifting control over Di2 that's on my partners bike. Her bike is a pain to change and adjust shifting.
  • So it makes me wonder, would I be better off grabbing an AL frame with tiagra and swapping the components out for Di2?

The real upgrade is di2 and imo very worth it. Its a real QOL inprovement. I would never go back to mech on a road bike.

Di2 lasts like 1500km on a charge. It tells you when it’s at 20% battery. Only if you’re a neglectful moron will it ever run dead.
