When I got my Trek 730 tuned up yesterday, I decided my next upgrade would be a B17 flyer saddle, to see whether or not I would like springs under the saddle. For longer rides with the 730, I would rather get away with a reasonable sized seat bag, before thinking about adding a rack and panniers, because I would not be carrying much weight in a bike bag besides tools, snacks, and a cell phone.
Both wallbike.com and the Brooks website offer info about the B17 flyer, and info about Brooks seat bags. However, neither websites offer information about which Brooks seat bags would work well with the B17 flyer saddle. In other words, it is not clear whether seat bags would interfere with the springs underneath the flyer saddle.
For cyclists that have a B17 flyer saddle, what kind of seat bag do you hang on the back of it, and have you had any problems with the bag interfering with the springs?
