Would you elaborate a little? Use a normal pulley puller or such with the
allen bolts in the chain rings?

thanks.

No. JG is saying you could get self-extractors. I think it's a stretch
to say that "modern cranks now come with" them, but they are
available.

Only $12.95:

So you bought new rings with the wrong bolt pattern, and now to save $10
on a crank puller, you want to destructively pull off your old cranks
and replace with new.

If the point is to save money, why don't you take your rings back and
exchange for ones that fit your 5-bolt cranks? *Then you don't need to
change your cranks at all.

This is the epitome of what I dislike about even asking questions here.

I ask a simple question, and in return get 9 more questions that have less to
do with answering my question than they do questioning the reasons I am doing
what I am doing.

If there was a way for all USENET to hear my frustration (rather than the few
readers of this thread) I would say:

ANSWER THE ORIGINAL QUESTION OR F'ING DON'T WRITE ANYTHING.

To those who actually did the former, thank you. I am grateful. *

Cut it with an oxy-acetelyne torch.

Good idea. But it's more of a convenience than a money saver, given
the cost
of the "one key release" kits. It sounds like this is all about
saving
money. Or simply trying to prove that something can be done without
the
right tools.

I just don't like buying tools I'll use once. The second time I need
it, I'll
buy it. But tools just to populate my shop? No. Not if I can borrow or
DIY a
tool.

He probably has an old HD. :-)

No (whatever that is).


Harley Davidson. Supposedly you could fix a lot of things with a hammer,
screwdriver and crescent wrench.

Pretty cool idea. Thanks.

I used a sawzall on a crankarm once after stripping the inner threads
with the puller.

I also beat one off with a hammer on an old peugeot from the
seventies that had a three bolt simplex crank. Now that job took some
time and I would not advise doing it on anything but a junk bike.

Along the lines of desperation I once used a Dremel and about 4 carbide
cutting wheels to get a crank off 'after' it had ruined my puller. It
was an el cheapo Chinese crank from Ebay. I know *must* have a reply as
to all 3 chain rings being separate entities rather than the removable 3
pieces as a until junk type.

I always prefer too look and feel but that takes 3 times more money at
the LBS's I have. If you aren't buying a bike then you are wasting their
time. The ex-Schwinn does that to me but not the ever independent
"Van's" who is run by a nice low key guy.

Side note;
Has anyone ever seen a square taper that looks like it is rotated 90
degrees from where it should be? I have seen one and it sits possibly
forever in the box of curiosities.
