Everything fits perfectly.
As you can see, there's a lot of room still from this 50T oval ring to go up further. Looks like it would fit a 53t if I could find one. Zee 640 has BCD 104, and only recently has Deckaz released an oval ring at 52T with this BCD. Will consider that as a potential upgrade later. This bike is only running 9 speed, with Sora drop levers that I was able to get on sale a few years back for about $130. I would like for this to be able to climb the outs from the metropark, and currently I question if the Dura Ace 11-23 cassette currently housed would make that possible (even in the pro gear). If I increase the chainring size, that possibility is going to slip further out of reach. I'd have to run 11-25 then, which is less favorable on the road with less intermediate gears.
