I bought this crankset a few weeks ago from another STer and it turns out I can’t use it on my MTN bike due to spindle length issues.
It is a 110/74 chainrings, rear wheel harness, red PCV and 25.4/26.0
handlebar clamp.
You can easily use this as a compact road crankset using an ultegra or dura ace octalink BB. It has a normal 110 bcd for the outer 2 chainrings and the inner 74 bcd ring one is bolted directly to the spider using standoff washers. By leaving off the inner chainring and standoff washers you have a normal 110 bcd compact crankset.
