Rear mech serendipity

Just zis Guy said:

Not that it would be reasonable to characterise cheap Shimano mechs as
[censored] or anything, but the cheap 7-speed Shimano rear mech on Michael's
bike has had it. The pivots have all gone so loose that the jockey
wheels are flapping in the breeze and shifting is erratic.

So I tried the spare Deore 9-speed mech I had in my box'o'bits,
expecting to have to do some nonsense with the cable pulls to get it
to work. Imagine my surprise when it worked flawlessly straight away!
No need to run the cable the wrong side of the pinch bolt or any of
the other wheezes suggested for making mismatched components work
together.

Yup, apart from some odd Dura-Ace stuff, all Shimano 6,7,8 or 9 speed
rear mechs are compatible.

The wheezes are for mixing Shimano and Campag

So, if your Tourney rear mech falls apart, I reckon a Deore one will
drop straight in to replace it. Which is a Good Thing since the Giant
Boulder Michael's been looking at for his birthday has Tourney, while
the equivalent Dawes has a much better Sram drivetrain but a
significantly less good front fork.

You shouldn't be so surprised, don't try it with Campag though.

Those 9-speed Deore mechs are fantastic value IMO. I replaced a slighly
dodgy 8-speed Acera mech with one and the difference was immediately
noticable. It shifts brilliantly.

This one was: SFP, sitting unused in my spares bin. Mind you, it was
only there because I'd spent a several of your earth "zbarl units" on
an XT one for the 'bent...

On the subject of which, I have now fitted an Avid Rollamajig to the
back end of the 'bent, which has improved shifitng dramatically. It
has a trailing arm which is more or less horizontal, so the cable has
to bent through a sharp 180 before entering the mech. The rollamajig
has this down to about a 70 degree gentle curve, much better.
