Well,better half right than totally wrong,I’m glad you’ve got it working ok.

Bastards. Now I’m going to have to try it on 2&3 to see if it fixes the slight mech rub problem! Up till now has been good as it needed to be!

No I don’t think it changes the ratio as such, i think it is more to do with slightly different total throw between 1-2 and 2-3. Possibly due to the change in pull angle relative to the FD pivot point.

ahh lots of posts while I was working out how to word my response to khanis post above.

So that did work. thought it would.

thejes – untwisted your knickers now? 😉 😀

Yeah. Agreed. One way or the other anyway.

You were on the right track. It was a team effort methinks. 🙂

Yes,I’m fine,haven’t had a drink for a couple of weeks,and I get tetchy sometimes,sorry.

So, if my logic is right, that means that the 1-2 shift requires a bigger cable pull than the 2-3 shift.
And I KNOW that the XT shifters with the 2/3 position switch lock out position 1, as I’ve serviced one.

I think this is it. I am sure that 1-2 and 2-3 feel different when shifting on a triple. Will try it out later as I want to make a mk2 of my DIY combined XT brake and shifter mounts (only way I could get my reverb remote under the bars and everything in a nice position).

@thejes:

(we need that adding, it is useful)

It’s been a very interesting thread, thanks everyone for your input. 🙂

I’m quite happy to use pos 2/3 if it saves me £65 on some new shifters. It works fine now.

I run 3×10 shifters on both bikes and noticed a lot of slack in the granny ring

Ignored it and it works ok – but will check the other solution mentioned above 🙂

Been fiddling, and I stick by what I said. 1 and 2 does work, but yep, I’ll admit it – 2 and 3 works better!

2/3 is the way forward! been using this setup for a few months now on my 26/38, but just upgraded to a new shifter today which shifts SO much better and is much lighter in its actuation!

also HURRAH FOR ISPEC!!!

Interesting thread, and solved something I’d been wondering about for a while – what was the point of that 2/3 switch on the new 10 speed shifters, as once you’d wound in the limit screw in the mech it couldn’t shift to the third position anyway. Now I know its because they want to force you to use the 2/3 position rather than the 1/2, but still don’t understand why? Variable pull ratios in a front shifter… hmmmm…
