I am looking for a rear rack to use on my Calfee tandem.
The two mounting options I prefer are brake mounting bolt or seatpost clamp.
I will be using Arkel T-28 panniers which on the smaller scale of size.
I would like the option of using rack top bag which I also have but honestly will most likely be using panniers.
The stoker's seatpost is a Specialized carbon and I am concerned about using a seatpost clamp like the Axiom product here:
This would allow a more secure attachment with a two arm rack compared to a brake bolt mounting. However we won't by carrying much weight because our touring will be done credit card style. Mostly we will be carrying extra cycling and street clothes and other necessities, so the brake bolt mounting might be a sufficient, viable and better option.
Some racks I am considering are the Tubus Fly and the Axiom Streamliner. I have read the Fly is too narrow to accept a rack top bag. The Streamliner has 4cm of setback which provides for better heel clearance which I am not sure I need since the Stoker has small feet and 165mm cranks. The rear spacing is 145mm so whatever rack I get I will need to spread it at the dropout mounting points.
I would appreciate any suggestions about which rack and mounting would be best, or if there are other options I should consider.
