puller. Can anyone give me a lead as to where to buy a puller for them -
tried my local stores but they can't help.

Could be 23.35mm dia - I have one but I'm rather far away. Go to a bike
shop that has been around longer than the bike.

Don't even think of trying a standard puller if that's what they are - it
WILL strip the threads.

They were 23.35mm up to 1982, according to Sheldon Brown's website. How
you get them off, in the absence of the correct tool, depends if you
want to reuse them. A 2-prong gear puller is quite gentle - a hacksaw
isn't ;-)

one will be the same size as a standard puller, the other, slightly
bigger, will be the same as the old TA cranks (cyclotouriste) and need a
puller of that size, otheriwse it will rip the threads out if you use a
standard puller

You need a specific Stronglight 49D tool. Not sure they are actually made
any more but there are still a few around at cycle jumbles.

I don't know where you'd buy one, but a decent, old-school
LBS will have one, and either lend it to you, or do the job
for you.

As someone else mentioned it sounds like the 49D chainset, the thread
is 23.35, so slightly larger than the 23.0 used by TA of that era. Its
been a while now but from memory Stronglight used 16mm heads on the
crank bolts.

Anyway one person you could try is Hard to Find phone number 01296
747377.

Assuming it is a 49D then this has the same crank bcd as the TA
Cyclotourist, and the complete chainring sets were interchangeable (but
not individual rings). For those not familier with the setup the outer
chainring bolts to the crankarm with 5 bolts, then the inner and middle
rings bolt to the outer with 6 bolts. The inner and middle rings are
identical with a minimum size of 26 teeth. Outers available from about
36 to 68 teeth. To get smaller inners it is necessary to have special
rings made that sit on extension bolts of the crankarm bolts, then you
can go down to about a 18 tooth inner!

The chainset can be either used as a single, double or triple with the
correct bolt and spacer sets.

One feature is the very close clearance between the outer face of the
outer chainring and the crankarm which makes it difficult to use modern
frnt derailleurs, the solution is to machine about 1mm of the thickness
of the outer ring on the face that sits against the crankarm, assuming
you have sufficient clearance for the rings by the chainstay.

Why would anyone want to still use these old fashioned cranksets? Well
they allow a small Q factor i.e. the pedals are close together which
some people myself included find more comfortable.

The stronglight extractor is a three piece design consisting of an
alloy tommy bar, a crank bolt socket drilled to take the tommy bar and
including pins to remove the crank dustcap, and an extractor unit that
screws into the crank and uses the crank bolt part to tighten up. A
light and compact design) I think VAR made (make?) a workshop tool.

Back to the original poster, I have an extracter that you can borrow
if you want, drop me an email at gwyn AT gwyn-oakley DOT org D0T uk.
and I will drop it in the post.

They also look gorgeous, functional but not agricultural.

I remember gazing in awe at the TA cranksets that use to be on Dawes
galaxies when I were a lad.

I can remember gazing with absolute longing at an aluminium chainset in
a bikeshop window, which had a pattern of drillings round each ring
with at least three different hole sizes. Beautifully finished as well.
I think it was a Campagnolo, but I'm not absolutely sure of that. Early
seventies. Anyone remember what model that would have been?

I don't think Campagnolo ever produced factory-drilled chainrings, but
there was a booming cottage industry of custom shops milling and drilling
standard Campag parts:

After the drillium craze became universal, several of the major
manufacturers began factory drilling. Stronglight, Sugino, and Zeus spring
to mind:

Campag's response was the fluted Super Record seatpost and drilled Super
Record brake levers.

Somewhere I have a copy of "Bicycle" magazine from circa 1983 featuring a
bike test on a machine sporting such a device. From memory the bike was an
Eclipse Routier and the chainset a Stronglight of some sort, but the mag is
at home and I'm in the Nut Mines.

I have hanging in the shed one of those slotted Zeus chainsets as shown
in almost brand new condition.
It came with titanium BB too.

Thanks for the replies. I eventually got hold of the correct tool via a pal
who borrowed the tool of a bike repairer in town. The threads stripped on
the one crank but no matter the chainrings are off on both. Pal was under
strict instructions not to let the tool out of his sight so he took them
off!

Once again thanks.
