Well said!
Would love to see a pic of your new Stanforth by the way. It should be against forum rules to say that you have a new Stanforth and then not post a pic of it! 😉

I would talk to Simon at Stanforth to see what he suggests. I have always found him very helpful. Which Stanforth model is it by the way?

When I picked up the bike he said that the rm was at the limit of its capacity, so I think he'll tut a little!

As requested by rareposter, here's a picture of the Skyelander:

It is if you're prepared to swap the LH brifter for a bar end gear changer. The LH brifter is replaced by (or just used as) a hydro brake lever. I rode a winter bike of this set up for some years.

It's not as convenient. But you don't change the front that often so ...... .

Also, if you use a friction bar-end lever, you can easily trim the front cage to avoid chain rub. Of course, it's easy enough to do that with a triple STI LH lever, as they have the small trim-movement-click that gets rid of chain rub in the more extreme chainline gears, once set up right. It's such setting up that seems to be the main issue causing the suggested "complexity" of triple derailleurs - but it's just a matter of RTFM then following the procedure therein.

That looks lovely!
I see what you mean about the chain but actually that doesn't look as bad as your initial description made it out to be. I'd just ride it. :-)

IIRC not all triple STIs work like that, and those which do don't all work the same way.

I bow you your wider experience.

The triple Shimano STIs I've used (from memory, 5603 and 6703) have worked that way (with the wee trim-movements). Which STI triples don't have the wee trim clicks, then? Which that do work that way don't match what front changers?

Perhaps there's a Shimano compatibility chart? But those one sees tend to err on the side of either caution or the desire to sell you more stuff when the stuff you have from different groupsets might actually match despite what Shimano says.

Well IIRC RSX triple STIs have no trim clicks and shimano have had several changes of mind re trim clicks.
There used to be a useful chart on the 'old' shimano website that explained which of the many different protocols you would get with each model. At one time it was possible to get at least three different types.
