Bent wheel rim

[Moose.]

After my spectacular tumble last month, I notice my rear wheel is now slightly bent. I guess it moves 1/4" at the most when rotating and it's not noticeable when I'm riding on roads etc. All the spokes are tight (after it'd tightened one of them) and the rear disc is fine. Should I be looking to replace it, get it straightened or just leave it? The wheel is a Mavic CrossRide

Depends on the length of the distortion - if its a small deviation over a couple of inches, you'll probably be best getting a new rim. If its over a 1/4 of the wheel or so, it should be possible to bring it back into line by truing the spokes.

Either way, unless you're good at truing wheels, take it to a bike shop.
