Bike adjustments question
Hi hi. - In May I bought a new bike at REI. It was a pricy bike (4K+) and the first I've owned in a looong time. The manufacturer said you should take it in for adjustments after the first month but I've also heard several other things like 100-200 miles even 500 miles. I'm at about 250 miles now. I've tried to take it to my local REI several times now, but have always been turned away saying the bike shop is too busy. Is this something I should be concerned about? I honestly don't know as I've not really owned a bike I've cared about before. Thank you so much for the help!
