Which Crank Arm Puller?
I hope I'm providing enough info.-
If I understand correctly, I can use this Park Tool: https://www.biketiresdirect.com/produ...7-crank-puller to remove the cranks from my '77 Super Mirage, or this one: https://www.biketiresdirect.com/produ...2-crank-puller
The former will work on another type of crank besides mine, but the latter will only work on the type my Super Mirage has? The prices are similar, is there a reason not to buy the one that will pull more than one type, if I'm understanding correctly?
I'm a newbie at this. (duh!)

I didn't open the links, but it's very straightforward. The crank remover has to have a pusher pad big enough to span the bolt hole of the spindle, yet smaller than the hole in the crank arm (minor diameter of the spindle).
Square taper cranks take a remover with a small pad, and the larger spline (aka Isis) spindles need the larger pad. Some removers come with 2 pusher pads, or are otherwise adaptable to fit either system.
In a pinch, you can use the smaller sq. taper remover on an Isis crank by putting a washer or disc across the face of the spindle so the pad has something to push against. You can also improvise the reverse by putting something onto the sq. spindle face to bring it out so the remover can push it without bottoming against the crank.

Yes the first is universal, while the CWP-22 is for sq. taper only.

You are correct, the CWP-7 comes with reversible pads, so it will remove both square taper and octalink or isis style cranks. The CCP-22 comes only with the push pad for square taper cranks. They should both work on your bike.
I use the CCCP-22 because I really like the integrated handle. The CWP-7 will do the job, but it is just one more nut that you need to put a wrench on and turn while holding your cranks stationary.

I think this cycles back to constant debate between the folks who buy bike tools and those who don't feel the should need to buy bike tools.
My rule is to make sure I own all the tools needed to service any bike I buy or I buy the missing tool at the same time. If the missing tool is unavailable, uncertain, or crazy expensive, I pass on buying that bike. I just don't need the hassle as there are lots of good bikes available that don't present tool issues.
fwiw

Thanks for all of the replies.
Gotcha.
Right now, I don't know what an isis or octalink style is, but I'm going to get the tool that does both should I run into them in the future.
I don't want to debate, I just want to get the right tool.
Then, what if it's a Super Mirage? ;-)
