You need a crank extractor:

And, unless you've already got one, a spanner of a suitable size for
turning the crank extractor. I use a 6" adjustable.

OK, ignore that URL. That takes you to the Wiggle page that I started
from before searching for "crank extractor". Try this one:

£12.99, having a laugh aren't they.

Have a look in Halfords or your local bike shop. It is a standard tool, but
don't pay an extra fiver just because it has Shimano stamped on it.

This is the one to get, Peter. The little spanner isn't much good for the
initial hard work but that doesn't matter as it's handy to have a large
adjustable spanner anyway.

Hi all again,
Thanks for the many replies.
I think I better add that I have many car tools, socket sets etc. so tools
are no problem.
Also I intend fitting a new chain and cassette. I have tools for both.
The thought in my mind regarding the extractor was "Is it a standard size or
are there many different ones" but noone has said there are different sizes
so iwill assume that is the case .
Thanks again Peter

Hi all,
Greetings and safe cycling to all.
This is my first post here.
I need to know what size/type tool i need to remove the crank on my atb.
I have looked on the web sites and seen what I think I need, but I need
confirmation.
The hole across the threads is about 20 m/m and the square shaft is about
12 m/mm across.
The reason is that my chainset is knackered. The bottom bracket is fine,

it

was replaced about six months ago.
My local shop has closed down and I need to start doing my own repairs.
Can any one advise me please.
regards Peter

Bolt Circle Diameter, and you only need to know it if you're changing
individual chain rings. It's the diameter of the circle on which
the /centres/ of the bolt holes of the bolts which attach the rings to
the spider sit.

Unless you have a very expensive chainset, it's often cheaper to replace
the whole chainset than to replace individual rings, so knowing the bolt
circle diameter isn't often that important. Obviously, /if/ you need to
know it, you also need to know how many bolts there are!

Thanks to all for the information . You have been very helpful.
By the way,
I read a few months ago in this group about attacks upon cyclists.
My experiences over the last two years:-
I have been struck on the back by a passing motor cyclist pillion
passenger.
Had unknown objects thrown at me by passengers in passing cars.
Had known objects (apple) (full can of drink)very painful thrown at and hit
me.
Shouted/screamed at countless times by inebriated young people.
And the the prize of all..................had two idiots with co2 fire
extinguishers run into the road and let them off at me.

I saw this one at the last minute and just closed myy eyes and braked.

They ran off up a grassy slope back to their dozen or so friends laughing
like a couple of silly girls.

A couple of cars stopped and checked if I was ok, decent of them.

The idiots and their friends just stood 20 yards away and were jumping up
and down laughing.

Their ages looked between 15 to 20.

safe cycling Peter

All these incidents were between 10.15pm and midnight, after I finish work.
