IRD BB and compact crank compatibility with Shimano
I am doing my first build on a factory repainted 1996 Marinoni Corsa columbus
brain 59cm steel frame. I bought a new silver shimano 105 5700 10 speed
group set with compact crank (50/34), CS5700 12/27, FD5700 braze on, from
ebay. It is the Hollowtech II bottom bracket and crank.
I am thinking of using The IRD Compact Double Road Crank which requires a 115mm JIS square tapered BB instead of the Hollowtech II BB and crank. Here is the site:

My questions are: Are there any compatiblity issues with the Shimano 5700 105 group I have? And specifically with maintaining the recommended chainline of 43.5mm?
