I have changed my chainset to my touring set, 48/38/28, chain lain isn't perfect as it should be on 110mm crank, so is set 1.5mm to far out on the new bb of 113mm, but it selects all the gears with minimal rub on the out ring and the large rear and a touch on the inner on the same, if I get that right I get some on the outer and small, will probably need to adjust the saddle height as they are 172.5mm crank arms opposed to the 170mm on the other chainset, I haven't reduced the chain length because I will be changing the chainset, to a outer of 50th, just need to watch it on the 28th and the three smaller rear, but as I wouldn't normally be on those it shouldn't be an issue I might take a link out as that would most likely still be long enough.
