Hi Bob, didn't see your post, glad
@Faust29 @mtnbikej addressed it! Any tire with the word "nano" in it's name would be good! The Nano40 is my everyday tire I do my non-MTB riding on. It rolls great on pave. No experience with the others you listed. A regular sized Nanoraptor would be good for this ride as well. I also like Thunder Burts a lot. Notice I'm veering to higher volume yet fast-rolling tires. The more comfortable you are, the better the ride will be! The 100km route is going to be closer to 2/3 dirt, so something that gives you comfort and grip is better. That said, there will be a good chunk of people on 25mm slicks. They can do it fine, but are going to carry bikes across the wash shown above, and have to ride the slippery ball-bearings on cement-like dirt trails a bit more cautiously
Glad you can make it and thanks for checking out this whole IMTB thing!!!!
