    Do you need a crank puller to remove 9sp Ultegra cranks?

    I'm upgrading and don't want to buy the tool if it's unnecessary.

    I assume you're referring to Hollowtech cranks that mate with an Octalink splined bottom bracket. And for these, you do need a crank puller. However, a traditional puller can work, so long as you buy or otherwise get ahold of a plug that screws into the hollow center of the splined bottom bracket spindle, so the crank puller has something to push against when pulling the crank out.

    +1 The dust caps operate as self-extractors.

    Ultegra and Dura Ace 9-speed cranks have self-extracting cranks. Loosen the crank fixing bolts and as you turn them out the will seem to tighten up again as the bolt's shoulder comes up against the outer ring (the ring with the two small dimples). Keep turning and the crank arm will come off.

    105 9-speed cranks do not have this feature and you need a specific crank puller or an insert that fits into the hollow spindle to use a conventional puller.
