I see 2 things with the Argon 18 Electron Pro that would give me pause:

- Steel track ends (as opposed to titanium). Ti is known to allow nuts to grip better.
- That seatpost top rail thing. Those tend to creep backwards.

Real talk (and not just fishing), do you friends have any gripes about it? I know top sprinters had A LOT of gripes about the TK1's first few iterations. Thankfully Felt responded quickly with changes (some worked, some didn't), until they got something stable.
