The Andel cranks are a good swap out for the RD2 cranks.
Have a look at your BB and check the measurements.
I have a few Precursa bikes with the stock set up of RD2 cranks and 103mm BB and the chain line is 42mm +/- a mm which is OK with the flexible chain that comes with them.
The Andel set I have runs with the Tange 107mm bracket and is OK for chain line.
