B-RAD3 on the downtube, B-RAD2 on the seattube. I have comically long arms, and the bottles are still positioned so low in the stock configuration that I have to contort myself to reach them. Seattube bottle is raised about an inch, downtube maybe inch and a half.
Bag is a Castelli Undersaddle Mini with the OEM strap removed. Fairly water-tight, and holds everything I need.
