Ignoring the original question about the SP hubs and focusing on the flickering that people are talking about....
I have the SON Deluxe Widebody with the Cyo Premium T. The light flickers at approximately .001 MPH, but by the time you're going 3 or 4 MPH, the light is solid. Truthfully, so far I have not been able to ride slow enough to make the light flicker while I am actually riding the bike. I would be willing to bet money that any other modern LED light would also operate well with this hub. I see many others riding different lights with SON Deluxe hubs in the RUSA clubs in Texas and elsewhere and nobody has a problem with flicking at realistic cycling speeds that will keep you from falling off your bike. I think this flicker issue is way overstated. You only need the SON non-deluxe if you are using old school lights like the E6, or if you are powering your phone and Garmin from the hub also. $0.02. If you do any sort of riding that will require a water bottle to maintain hydration, you will want the lower rolling resistance of the SON Deluxe. The hub operation is barely perceptible. My seat-of-the-pants opinion is that the old school SON28s and the Shimano hubs have much more rolling resistance. I have owned all three types and I put thousands of kilometers in brevets on both the SON28 and the Shimano hubs and after having a SON Deluxe for a few months, I would never go back. The ones with more resistance are fine for just puttering around within a few miles of your house. Now, back to the original topic, I am intrigued by the Shutter Precision hubs, but there they have a similar question between the PV-8 and the SV-8 which has lower rolling resistance. I don't know if it's similar to the SON28/SON deluxe, but I look forward to seeing this question answered. -Jim On Tue, Oct 7, 2014 at 4:14 PM, 'Rick' via RBW Owners Bunch <rbw-owners-bunch@googlegroups.com> wrote: > What size tire?
