Review: WTB's Revised Tough Casing Tires
@AndrewCuretonrlD: The wheel/tire combos are effectively flywheels with a gyroscopic effect on the bike. Adding more mass to the perimeter of the flywheel makes it harder to accelerate much more so than adding the equivalent mass any where else on the bike. This perimeter weighted flywheel imparts a gyroscopic force which tends to keep the bike upright. I doubt many people will be able to specifically feel the difference while riding at a normal trail speed but this gyro force is part of why bicycles are more stable at speed than they are in a track stand.
It also has the effect of changing suspension dynamics due to unsprung mass as you've mentioned.

First Ride: e*thirteen's Sidekick Hub Elegantly Isolates Suspension Movement
Different approaches optimized for different aspects of riding. I really like my high engagement hub when I'm riding technical climbing trails that have roots and rocks that I need to ratchet over. I'm not paying for high engagement hubs for gravity riding and I wouldn't put this or an O-chain on my trail bike. I don't have any experience with Enduro racing, I assume they'll accept some sacrifices in the climb since the competitively timed portions of the race are downhill.

First Look: Forge+Bond Fusionfiber Bar Claims '3x Better Vibration Damping'
A thermoplastic by definition melts at some temperature and hardens again when it cools. A thermoset hardens and only melts/softens at a higher temperature and often doesn't flow at that point. If the matrix is nylon-based then it's conceivable that recycling would done by heating the component up above the melting point of nylon, draining the flowing nylon away from the carbon and having the two separate elements.
I have a pair of Evil Loopholes which are private-labeled Forge and Bond fusion fiber hoops. The compliance was very noticeable when I switched from a set of E13 hoops. I actually have high hopes that these bars would be an equal improvement.

Spokane Trail Saboteur Pours Grease on Rock Slab, Threatens Further Action
@barp: I think the "green" is only a reference to EverGREEN Mountain Bike Alliance.

Movies For Your Monday - Tom van Steenbergen, Hannah Bergemann, Ashima Shiraishi, & More
My take on Real X-game videos are that they give the athletes a chance to showcase their skills on their own terms outside the confines of a specific competition venue. It gives the athletes a chance to expand their boundaries and ride terrain or obstacles that they want to ride. I don't think the bike editions are any different except that it takes a lot more work to build a bike trail for one video part than a lot of the skate and snowboard edits.

Hood River Super D Returns June 27th!
Why does this have to be the same weekend as the Fluidride DH race? Is it doable to get both races in?
