I am noting a real increase in vibration from what I assume is the chain... I have 18k on it with a lot of loaded up riding and me being in the 250# range... my guess is that I do have a worn front sprocket, and the rear is worn a bit... the chain however measures great with a good 13mm before it hits the 321mm mark.
I meant to ask about vibration but forgot... because I have noted and increase feel through the feet.... if the drive chain setup is causing this much feel in the feet, what is it doing to the drive chain a head of the front sprocket...?
I think I am OK for the rest of the season and I'll do a complete change over in the winter to new chain and sprockets...
thanks for the responses
