Chain wear is based on multiple factors including maintenance (clean/lube), use conditions (water/mud/sand), user shifting patterns and overall drive train condition (cassette/ chain ring wear). If you do not have a gauge to test the chain’s elongation you could roughly check by putting the chain on the outer chain ring and lifting up the chain from the middle of the chain ring. If you can lift it more than half a link, the chain or chain ring, or both, are probably worn. Your Carqon dealer can advise you on the condition of your bike’s chain and whether it needs to be replaced. Also keep in mind that it’s advised to have sprockets replaced at the same time, if needed.

Have the sprocket and/or the chain wheel replaced by a Carqon dealer if you notice that individual teeth are dangerously sharp (so-called shark teeth) (1) or (2).

• Contact a Carqon dealer if components show signs of damage, if you notice unusual sounds when shifting gears or if you are unable to shift through all of the gears in a proper manner.
• Maintain the derailleur gear components with suitable maintenance products in order to reduce wear and tear through weather and environmental influences.
