Cannondale SR series - what crankset puller?
I've got two 1988 Cannondale SR series frames with cranksets that need to be removed. There is a hex nut that sits inside the crank that secures it.
Similar to this type: https://www.youtube.com/watch?v=JrMqzIQEjN0
Only issue is that none of my standard nut sockets would fit in because the crankset's body is bulky. Suggestions?

Well, somebody got it on there so there must be a tool which will fit. Newer and cheaper sockets tend to have thicker walls. The old (non-Chinese) Craftsman sockets were notably thin-walled, as are Snap-On. Perhaps one of those is your answer. Or get a cheap one and grind down the outer diameter.

As noted, better quality 14 mm sockets (the most likely size but 15 mm is also a possibility) have thinner walls and should work. Park Tools made a multi-size box/socket wrench (CCW-2) that had thin walls around the socket openings and fit 14, 15 and 16 mm crank nuts and bolts but it's no longer listed. They still make the CCW-5 but it's limited to 14 mm bolts and nuts. At worst, take the bike to a bike shop and see what they use.

Grind down a socket on a bench grinder, or buy a crank bolt wrench.

That was the word I was looking for -- crank bolt wrench. I'll probably order one online -- cheaper than paying someone to do it!
