cadenceblur Posted June 8, 2017 Posted June 8, 2017 Hi guys Please have a look at the video. You will hear rubbing noise and see chain rubbing against cage. Is this a warped chain ring?

100Tours Posted June 8, 2017 Posted June 8, 2017 Something bent? either that or the BB is loose. 2 tests you can try - If you take the chainring off and put it on a table you would be able to see if it is flat or not.- if you wiggle the cranks you'll quickly see if they are loose / BB is loose
johannrissik Posted June 8, 2017 Posted June 8, 2017 Chainring is clearly not running flat. Check that all the chainring bolts are secure. If they are, you may need to gently correct (bend) the chainring outwards. The other knocking sound I have no idea Good luck

Spoke101 Posted June 9, 2017 Posted June 9, 2017 A sticker in the wrong place? Nope, bolt seams to not be tight/cross treaded causing the step between small and big chainrings.

cadenceblur Posted June 9, 2017 Author Posted June 9, 2017 Was the chain ring bolt loose?Yeah - actually the thread is stripped - hopefully a new bolt will do the trick and the spider thread is not stuffed as well.
