Default Shimano/Taya/Sigma chain link - what's the secret ?

No tools it said - what a clever idea I thought.
Not unless you have the fingers of a rock climber , or what is the secret.
One thing I learnt long, long ago , tie a bit of wire a few links back
either side of the link before removing or replacing to take the tension off
the link area.

With these links the only way I could put one end on the pin and then just
preliminary place the other one was to put a bit of a set in that closure
link, so it would slide over the top of the second pin when firmly pushed by
finger.
Then 2 pairs of molegrips, not particularly firmly gripping but enough to be
able to flex the made-bridge piece enough to complete the locked closure.

I don't know exactly what product you're talking about. Can you post a link
to a picture?

SRAM Powerlinks are easy to manage without tools once you get the knack.
Not easy to describe in words, though. Please search the uk.rec.cycling
archives (via Google Groups) for attempts.

Flexing doesn't sound a good idea. You do not want to cause damage and
increase chance of snapping.

Taya Sigma link is this:
http://www.halfords.com/webapp/wcs/s...oryrn_10370 4
http://www.bike-x.co.uk/index.php?cP... 409581fa97c17

Also this: crap. I used one once[1], and won't be using one again.

[1] Because Halfords was open at 7.30pm and LBS wasn't, and I didn't know
better at the time.

Alan Braggins tweaked the Babbage-Engine to

Mine has never failed yet, but then it's only used for joing the ends of the
Mayoral Chain :-)

Thanks. The shape of the holes are quite different from SRAM's.

N_Cook, if it's for 7, 8 or 9-speed, get yourself a SRAM Powerlink
(appropriate speed), is my advice. After several years of using them in
several chains, I know they work well.

For 10-speed I use Wipperman Connex.

I like Halfraud's photo zoom facility, btw.

There is one type that you can buy in Halfords where you bend the chain at
the link undo it. It's identifiable by having the two pins on one plate
and two holes in the other. It should go together OK when new
but I had problems getting them undone and then they were bent so not easy
to use again (the instructions said they could only be used once).

The SRAM ones are much better IMO and to open them you just squeeze and
push together. They have one pin and one hole on each side and they don't
mention any limit on the number of times they can be opened and closed
(although one of mine seems a little dodgy at the moment). I think
they're no more expensive than the crap one Halfords sell.
