You're just moving up 4 teeth on each ring, so just put the derailleur higher up the seat tube - the difference between inner and outer is still 22t
You might have to add a link or two to the chain as well.

It might not be quite as easy to set up (i.e. it might need to be 'just so'), and/or may not change quite as cleanly, but I would have thought it would work.
The reasons for my 'mights' is that the 48 outer will have a larger circumference and so a slightly different shape to the 44. If your mech was designed for the smaller circumference of the 44 then it might not work as smoothly.

Hmmm, that's odd. I felt sure I added a final line to my post... something along the lines of
as always, my advice in such situations is 'suck it and see'
kind of coincidental you've used exactly those words bod! best of luck, setting up a rear mech is perhaps the most frustrating thing I've done on a bike.
There are a number of different design parameters for a front mech (span, chainwheel size(s), frame angles, curvature, etc etc etc) that make it quite difficult for the uninitiated (like myself!) to know whether you're not setting it up correctly OR it's the wrong mech design and it will never work!

Yes, I know have a go and find out is the only wayyello said:
. But I have found the hard way, like you say, buying stuff too much without thought can result in stuff not working and ending up with too many variable to work out easily why. I could afford that last year, now I need to be more careful !

Well the BB on the runabout is offering up a fair bit of resistance, the BB was 2nd hand off eBay and has not lasted long. Rather than messing about with more false economies thinking just to buy a new chainset and go to 48/36/26 which seems more suitable gearing for the use it's getting.peanut said:
