cadenceblur Posted June 8, 2017 Share 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? Link to comment Share on other sites More sharing options...

100Tours Posted June 8, 2017 Share 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 Link to comment Share on other sites More sharing options...

johannrissik Posted June 8, 2017 Share 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 Link to comment Share on other sites More sharing options...

Spoke101 Posted June 9, 2017 Share A sticker in the wrong place? Nope, bolt seams to not be tight/cross treaded causing the step between small and big chainrings. cadenceblur and johannrissik 2 Link to comment Share on other sites More sharing options...

cadenceblur Posted June 9, 2017 Share 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. johannrissik and Long Wheel Base 2 Link to comment Share on other sites More sharing options...
Long Wheel Base Posted June 9, 2017 Share Yeah - actually the thread is stripped - hopefully a new bolt will do the trick and the spider thread is not stuffed as well.Hope so too, That would be an expensive exercise. Link to comment Share on other sites More sharing options...
