Like I said I can't really hear he noise but can feel it through the pegs! When I'm starting off on low revs you can really feel it and it almost feels as though something is maybe shaking a bit. On higher revs the pegs are vibrating but definitely more than what is normal! I would say it is coming from the gearbox but I'm not certain about that.
My front and rear sprockets do need changing which I'm doing on Sunday (the chain is in good nick) as the teeth are just starting to fold ever so slightly so I'm hoping it's somehow them causing it.
Has anyone had worn sprockets causing something like this or do you reckon something's wrong inside?

And it's not related to my post the other day about downshifting because it started before that

Cheers
