HillRider thanks for your input. This being said, I don't understand why that is going to be a problem. I mean, the 26T (I've actually swapped a 22T) is much lower than the FD's cage, yet it shifts very well. I (naively) thought that lowering the FD, perhaps with a wee bit of excess clearance WRT the larger chainring, would work well... funny as something that looks simple on the surface turns out to be difficult to implement
