i have the slr one and there are a few things i dislike.

- d shape seat post is over expensive and fragile.
- the rear seatstays require a longer seatpost or you might risk to crack one (for my friend i repaired a 2018 slr 3 with this problem).
- headset require his own brand stem or willl it looks ugly as heck.
- the paint and clear coat is basically is so think, it will flake whitout any reason.

bike is pretty solid and rigid but for the price probably there are more good around.
im late, im going to add more on the list later
