Thanks all. Cost wasn't an issue as I have various chainrings and cogs. Ended up for now going to 42/16 from 42/14. My chainring bolts are too long and I have washers taking up the space so switching the chainring to a smaller one wasn't going to work, chain hits the washer and my cranks have different bcd so no swapping from the shimano to the campy. Since I was fixing the bike already I decided to change the crank, chain and front wheel as well for winter. What I can do when my wife is away. Now the worlds second ugliest fg bike is ready for the winter, more or less.
