Beware of the self-extracting bolts which come fitted to the Stronglight cranks as they are crappy cheap aluminium: you can well end up with no internal threads in the bolt-hole and therefore no way to remove crank arm, even with a proper crank puller. That´s what happened to a friend of mine. Replace them if possible. The Stronglight are fairly OK, esp. for price, but not particularly well-finished.
