Vibration/Whine around 20mph

[darrsi]

I increased the tyre pressures to 42R and 36F yesterday evening and took it for a short ride. The issue is still there, so I've ruled out tyre pressures at least.

I think the whine is still there at higher speeds, but the vibration is only really felt at around the 20mph mark when I'm slowing to a stop. The whine is most noticeable around 25mph.

I'll have a look round the chain this afternoon and see if the chain is rubbing on the guide, causing the whine and I'll also check the slack on the chain as per the posts above. I'll report back this afternoon.

You won't see it rubbing, you'll just hear it. It's not a problem as such, just annoying for a while.


Put the bike on the centre stand and spin the rear wheel, if the wheel isn't aligned properly you'll see and hear that it's not right.


It should just be a faint buzzing noise of the chain, rather than any clunking noises as the chain is fighting an incorrect angle of the sprocket.
