For the Shimano 7801-SL wheel, I've narrowed my tire choice to Michelin's Pro2 Race. The attached chart shows this tire got good ratings as far as weight, puncture resistance, and rolling resistance:

I thought selection of tubes for this tire (or any tire) would be a no-brainer, but there are choices to be made. But at least I know I want the Presta valve.
I never knew the tube weights could fluctuate so much, from 75 to 175 grams. I first assumed that to make it simple, I should just get a Michelin tube for the Michelin Pro2 Race. But Performance Bike only sells one Michelin tube, and as far as I can tell, it's the only tire tube that Michelin makes. Is this correct?

I don't know if it matters, but the Michelin tube that Performance bike sells is "for aero rims". As far as I can tell, the Shimano 7801-SL is not an aero rim. So is it redundant to get a long valve stem for this wheel?
For the 7801-SL wheels and the Pro2 Race tires ... and for club rides:
1. Does it matter on the length of the presta valve stem?
2. Does it matter if the valve stem is threaded or not?
3. What are recommended tire tubes to consider?
