Cuchini…incredible. I think one of them said “camelflage” by accident!
OP, relax and take an interest in what she talks to you about. Strike up conversation on shared ground and find out what she likes/doesn’t and build on that. The bike thing may work but remember that she just may not relate to it as much as you but still enjoy it to the same degree.
Be yourself, pay attention and try not to show off. Making them laugh is key! But for the right reasons 😉 Ask her if she fancies grabbing a coffee or something in a relaxed 1:1 way and get chatting. Listening is a big deal too.
The balance varies for each person, pay attention and you’ll figure it out.
Oh, and don’t mention how you discussed this with a bunch of strangers who happen to be bike nerds. Not cool. Maybe further down the line as an amusing anecdote but not yet, it’s too fresh.
