I bought 2 R240s this spring during one of their sales.
This one I had drilled at the factory:
DT ~1-2 o'clock
ST front of tube on driveside below clamp
CS, in front of the housing stop on the bottom of the tube.
This one I drilled myself, I think it looks a bit cleaner:
HT next to the head badge
ST, same as factory drilling
R Rear dropout (saw this location on a Foundry with identical dropouts.
