...sadly I can't really hear much noise from the rear wheel. The front is definitely talking though.
The combination is great so far, with slightly higher cruise speeds for me, and noticeably higher downhill speeds. I think I'm getting 1 or 2 km/hour on the flat at above 32km/hour, and 3 or 4 km/hr on the fast downhills. Mostly the joy comes from the pose factor of course.
