loi is talking some BS.
no offense, but you should stop because this dude's takign you seriously.
1st off, the blue bike does not look like a 52-56, i dont even know how loi could even say that from a picture. lol
2nd, you can use a 1/8" chain and cog witht he 3/32 road cranks.
he really doesnt know what he's talking about, so ignore him.
