Wav, the Nexus RL 8 is significantly lighter than the S-A 7. The other factor is changing flats on the rear. I'm familiar with the stow-a-spare technique, but I don't have fenders on the Swift on which to cable-tie the spare tube. Maybe because of doing it every trip, but I can set up an RD faster than the LBS (which has high turnover in techs, admittedly). That's the Swift. DT is a diff story: I do want a Red Label for a strange reason.... bus bike racks trash the RD on my DT FS. The racks don't bother RDs on 700c wheels, but on the 406s.... mangle city.
