I have a Triban 120, Id say go for them, they're very good entry level bikes.

You could get a Triban 520 under 1000 euros as well, you get a Shimano 105 groupset which is kinda the gold standard for value.

I wouldn't go for a carbon bike that cheap, those thing tend to crack if they're not properly made. Maybe check out something like a used Orbea Orca

Death of a man is a tragedy, death of a million is a statistic

That's such an aquarius thing to post
