You bought a new bike under warranty, and it immediately came out of adjustment. Why is the dealer not servicing it for you?


I would guess the wheel wasn't built perfectly, and you aren't necessarily improving it simply by truing it. Straight wheels aren't necessarily evenly tensioned wheels, and your spoke elbows probably need seating.

So you can take it to the dealer, complain to the manufacturer, or take it to some other professional for seating and retensioning.
