  💡 Michel's Tip (Magickart):

  "A 70-teeth crown in good condition, it's a chain that lasts twice as long!

  My Pro Council: Never climb a new crown with a used chain. The 'elongated' channel will "eat" the teeth of your new crown in just two sessions.

  The secret: Check the alignment of your rear sprocket. If the crown wears more on a flank of the teeth is that your engine is not perfectly right on its support. "
