So looking at the Sugino RD's it shows that you will get a 45mm chainline. I have looked all over, including multiple old threads on this forum and can't really figure out if this will be acceptable or not, vs trying to get closer to the standard 42mm. Some people say it works fine, some say it doesn't, some say it depends on your rear cog brand, etc... Now this bike is for street use not the track but I would like to make it as smooth running as possible for lot's of 3+ hour rides. I'm just wondering if the RD's are the best way to go. I don't want to spend the $ and move up to the 75's. The iro crankset looks fine but I would rather have a higher gear than what it comes with + the fact that once you start buying a bunch of iro parts with the frame you are better off just buying a complete bike for the $ and I don't want to do that. I do think I am going to get a set of new wheels from IRO though.

I don't really care what's cool, what's track, what's not, just want to go with something that works. Any thoughts on the RD's chainline and if 45mm is too out of wack vs. trying to get to 42?

Also thinking of going 3/32 right now.

Thanks,
