Vibration felt in the rear at higher speeds

I know i'll probably get flamed a bit for this but for my safety i feel i should ask.


Around 100mph i can feel a slight vibration coming from the rear tire. I think it might be the two adjusters aren't lined up completely from when i changed my sprocket.


Any suggestions?

Yea I would check the wheel alignment. Maybe even check if your tire is balanced. Any unusual tire wear?

No unusual wear that i can see, the tire has at most 600 miles on it.

$15 for a cheap micrometer and use it in the gaps on the adjusters - if they are the same it's not that - other possibilities include a bad wheel bearing

If you can wiggle the bearing in the hub with your fingers it's definitely bad - free play on those things is next to nothing - otherwise it's a feel thing to see if there's a bad spot on the bearing

If the bike hasn't had an argument with gravity ever (aka crashed) I'd start with the adjusters and finger check the bearings afterwards

Also check the rim for any flat spots or if it is bent.
