Slightly crunchy drivetrain?

I don't know how better to describe it but my drivetrain isn't as silky smooth as it used to be. I have about 8,000 miles on the bike and the BB is pretty new. My freehub body has a tiny bit of play in it (it's older than the bike). Is it possible that if there is a bit of play in the freehub body (and therefore cassette) that I would feel it in the pedaling?

I've cleaned and relubed so I don't think that's the issue.

It's not audible. I can just feel it.

With 8K on the bike and no mention of replacement parts being installed over time there's every possibility that stuff is wearing out. First order would be chain and cog/ring teeth. Second would be bearing surfaces in hubs and/or BB. Next might be spoke crossings or nipples in rim.

There's got to be a good shop in Gainesville that can touch, look at, test ride and give their view. This kind of long distance assessment is wrought with assumptions and wrong. Andy.

I try to do all the service I can...with help from the interwebs. I've gone through several chains and the BB is relatively new. The cassette and chainrings are original but they look ok to me. If I can't figure it out and fix it myself then yes, I'll take it to the shop.

Ah, more data. 8K on a cassette is a LOT. Given current ring materials and designs I'd say 8K is also a lot on them. Then there's the pulleys... Andy

Thanks. New cassette ordered. If that isn't the issue then I've got a spare for when it does need replacing. For some reason I thought cassettes lasted much longer if you change the chain before it gets really stretched. I searched a bit and it does seem that 8k miles is about right for a cassette.

Update: New cassette was the solution. All good now!
