I called up Bike Stop and what a friendly company! Jeff, the rep who answered my call was super nice and look for some alternative products that may satisfy my need for a 3-speed hub that allows a disk brake and is also cassette ready. Unfortunately nothing. Jeff had a great attitude though and was friendly even though his company wasn't able to get me what I was looking for.
I did learn from him though that Sturmey Archer commonly releases only certain products in certain parts of the world. I may have to contact their Netherlands office to get what I'm looking for.
Good news! I came across the Sunrace blog and they have a picture of the CS-RK3! It's a shot from the 2010 Taipei International Bike show.
There's a guy on another forum that has his own shop that sells these! I'm contacting him ASAP. The source is here and I'm getting if my BROL deal doesn't go through.
