Dynohub + Drum: Sturmey-Archer or SRAM?
I'm working on upgrading an old 3-speed to use as a low maintenance urban commuter. As part of this upgrade, I'm trying to decide between the Sturmey-Archer XF-DD (combined dynamo and drum hub) and the SRAM i-Light with an added i-Brake. My problem is that I have been able to find only a few reviews on the SA hub, and almost nothing on the SRAM products. The price and specifications seem quite similar for the two hubs (although the SRAM is easier to find in stock). So, does anyone here have experience with these hubs (or with the i-Brake on another hub)?
