^^ Easier than that is...

Boil a pot of water, take the bike outside, splash said hot water (be careful!) on crank arm, and you should be able to take off the crank (with a pair of gloves on). While I have never tried this, I have heard of it working. It relies mainly on the fact that your aluminum crank will expand greater than the steel bb spindle, leaving just enough room to slip the crank off. Couldn't hurt to give it a shot.

Use Skype, it's cheap and it works.

See if your shop will chase them out the next size up and sell you a single self extracting bolt. Cost you a couple bucks.

I did this a couple years ago while trying to remove my crankarm really drunk, and never took out the crank bolt. I'll admit it...

but... it expands in all directions, thereby grabbing the spindle even harder. this doesn't make sense.

I actually have this tool; it's a ball joint pickle fork. My biggest concern ab trying this was marring up the drive side bb cup. Did this damage yours at all?

Last night I attempted to lightly tap the back of the crank arm with a hammer and a punch and rag. I didn't really get to into it before I quit. I'll be building my new wheels tonight, so I have some time before I attempt to pull the crank arm.

HERESY! The Sugino 75 is made with superior technology and is well worth every penny! They even put that magic dust on it, so $200 is cheap for such stellar cranks! Every gullible hypster with too much money and half a brain knows this.

Prepare to be crucified by a horde of abovementioned hypsters who purchased a Sugino 75 and need to justify spending too much for two pieces of forged aluminum.

Oh wow! That crankset has a lot of magic dust on, too! $250 guarantees a lot of magic dust - just look at that number: 250 That's a guarantee right there.

Best of all, the chainring is made of 6061 aluminum, which normally is really too soft for a chainring - but due to the magic dust, this one will last very long, defying all laws of physics.

What other NJS crank would you suggest to compliment my NJS frame? I'm just not about buying used square taper cranks, so what other options does that leave me?

There's nothing wrong w Sugino 75's.

EDIT: was the "magic dust" thing funny enough to warrant two posts?

Where are you racing that the track officials are checking your gear for the NJS cert?

I like my bike to carry a certain NJS vintage, nothing wrong with that.

Dura Ace?

The more you spend on a product, the more you are willing to believe it was worth it, even if the only thing that makes it special is the price itself.

I could spend the same on Srams, which I bought for this bike, but they wouldn't work because of spider interference w the chainstay.

I could have gone w Dura Ace, but what makes Dura Ace better than Sugino? I've never been a big fan of Shimano, and they're more expensive than 75's.

Again, there's plenty of other options, but like I said, I'm not one to buy used square taper cranks. I want my cranks/bb/and frame to be matching NJS, so Sugino is the most viable option. Do you feel the same way ab Grand Mightys?

Tell me what amazing crankset you prefer woroormwowomwwowm****

I prefer a crankset that is just as good as your Sugino 75, and costs between 1/4er to 1/3rd of what you paid. Actually, now that you splurged a total of $300 on it, that would be between 1/6th to 1/5th. I get to spend the rest of the money to bring my wife to the movies and dinner.

Little edit: I find it amazing and very telling that you are more offended by my assertion that you spent too much money on a crankset, than you are at people saying that you are too dumb to correctly use a crank puller. For the record, I never doubted that you followed a correct procedure when (trying to) remove the cranks from the spindle, even though I myself have never stripped the threads while pulling a crank. Oh, and I have that same Park Tool crank puller.

Steelwool... just waiting to install them. Had a back wheel destruction I need to deal with first. Any reason for the JNS zeal in Texas other than it complements the build? ( i can understand that, a build is a build)

What leads you to believe I'm offended by you telling me I shouldn't have spent my money on Sugino 75's?

I spent $244 for my set w chainring, plus the $100 for the new arms to replace my stripped one, so I've spent closer to $350 on them. It sucks, but hell, what can I do. I'm not sure why you're trying to single me out on an anonymous chat forum.

How come you didn't tell me what cranks you're using?

You can try to fix the problem with someone who can actually help you instead of creating drama on an internet message board. Just an idea.....

Yo!,

I enjoyed your posts. I in no way find you to be creating drama, lying, or making anything up. I have to admit your experience is strange but strange doesn't me bad. It just means strange. Your original and follow up posts come across as legitimate. Sugino 75 cranks are in no way an excessive purchase. I'm not sure where that sort of talk is coming from. I also don't get the drama accusation. Weird. Anyway, I'm glad you got a fresh set without breaking the bank. +1 to your lbs.

Well, you would say that, wouldn't you, seeing as though you have shelled out $200 for two pieces of forged aluminum yourself.

Look guys, you can do whatever you want with your money, but just because your crankset is 3 times more expensive than another crankset of the same quality, doesn't make your crankset better, just your pockets emptier.

And the only way you can't find the cheaper cranksets is if you don't want to find them. The barrier between you and the cheaper and justas good cranksets, is 3 seconds of googling. But then you would have to admit that you have been taken in by marketing (and maybe peer pressure?). It takes a lot of self-confidence to admit that you were wrong.

I'm not sure what you mean about that "drama" comment, though.

Why so defensive ab Sugino 75's?

It's a good crankset. Sugino's been in the market since 1910, and the Sugino 75 was introduced in 1985, "marking the pinnacle of the company's achievement". It has a long history with track users for a reason.

I'm still wondering why you're shirking the question of what cranks you use. If you come back and tell me you're running $50 origin 8 cranks than this whole conversation seems to be based around crank envy. Nice. You can do what you want w your money, just like I can with mine.

Appreciate that. Permission is always a nice thing. I don't own Sugino 75's. I'm getting Paul's on my new steed. You would blow a gasket if you knew what an investment that project is. Feel terrible about it, too. But, I'm still going to take my wife out to dinner (as you said you enjoy doing) and since grandma has the kids this Friday a nice hotel is in the works. I'm no doubt over-paying for that, too. I bet a nice hostel is just a few Google clicks away. Eh, I'm partial to in room Jacuzzis though. I see them as the Paul crank arms of hotel amenities. But, I want you to know I'm going to feel stupid and used. I'm such a victim. It sucks being me. I wish I were smart, like you.

Yo!

After looking over where I took the pickling fork to my crank arm, it did marr the outer lip of the bottom bracket just a little bit. If I were you, I wouldn't be too worried about this, as it in no way damages or hinders the performance of the bearings. If you are worried, maybe stick a thin piece of metal and cloth on top of the bb to protect it. To me, the pickle fork seems like the easiest method.
My story kind of ironically matches this post in numerous ways: 1) I had to extract my old cranks in a non-traditional way, 2) I was replacing my old cranks with a brand new set of Sugino 75s, and 3) I was replacing a set of sh***y origin8 cranks, and just for the record, 75s are way stiffer and a much better setup, but I shouldn't have to tell any experienced riders that!

As a side note, I still dont see why you would want to run an open-bearing bottom bracket on your street bike. Its just impractical.

I'm going to guess to maintain the NJS-ness of the bike.

Right right, I would have preferred the phil bb, but funds wouldn't permit it.

tl;dr


1. OP: Are *all* of the threads gone? I've seen this happen a bunch of times, but usually only when the crank puller was only threaded in part way.
2. OP: You can still pull a crank arm with stripped threads using an automotive rod puller
3. Sugino makes excellent products. Solid company, too. I met Mr Sugino last week in Kyoto and talking with him for a while I honestly am going with Sugino automatically next time I need new cranks, now that I know the quality of people behind the company.
