Closer inspection shows that the roller on one of the links
has split and looks like it's about to fall off. The chain
is a Shimano HG50 narrow, can I get away with replacing
that link? LBS 1 Ac**on B**es says no trouble but they
don't have any narrow chains in stock. LBS 2 Ev**s say, oh,
no, the chain is on it's way out, only a matter of time
before another one goes...new chain and new cassette.

I would buy the new chain, use a couple of links off the end
to replace the dodgy one, then when the next link fails
you've already got the chain in the spares box.

On my ride into work today the chain slipped a few times
and had some trouble changing gears.

Probably, but with a bit of luck, your chain is a little
longer than it needs to be*. If so, I suggest removing the
dodgy bit and rejoining with an SRAM 8-speed Powerlink (£1).
Job will be much easier; result more reliable & convenient.

* Select largest chairing with largest sprocket and judge
whether rear derailleur is at full stretch or not. See
