misaligned cassette / sprocket thingy?

[primalgeek]

I've just fixed a rear puncture and after I put the wheel back on I lifted the wheel off the ground, turned the pedals and let the rear wheel free-wheel to make sure everything was ok. I noticed the cassette / sprockets (is that the right terminology?) seems to have a slight wobble to it. The wheel is turning freely and seems to be aligned. I've also checked that the wheel is seated properly on the frame and everything looks to be ok apart from the angled sprockets.

Are the seemingly angled sprockets something I should be worrying about?

It probably just looks wobbly.
The teeth on a cassette have all sorts of weird shapes and variations in thickness going on, which can make it look as if the thing's on wonky and terminally worn.
If it rides and shifts OK it almost certainly is.

Thanks Doctor! Everything else does seem fine so I will rest easy now
