WTB Ranger 2.8-inch TCS Light High-Grip Tire - Review
Three inch tires are an option, but you need to mount them to 40 or 45mm rims to get enough support in the turns. Not every plus bike comes with rims that wide.

The Tuesday Tune Ep 3 - Air Springs and Volume Spacers
A coil spring extends to its manufactured length and stops, so it stores no energy at full extension. That allows rebound friction to ease the shock or fork to a stop - One of the main reasons they feel so supple in the small bumps, and don't "top out." By contrast, an air spring has a huge amount of energy in storage at full extension due to its static pressure. A negative spring opposes that static pressure, reducing the stored energy to zero at full extension (in the best-case scenario) so the air spring will act like a coil in the first 25-percent of its travel. There is so little volume in the negative spring that it ramps up quickly at full extension and in reverse, becomes ineffective shortly after the compression stroke begins.

History and Deception - Opinion
@pinkypie Got the 530 watt info from the Specialized website and got the same number over the phone for a fact check. "530 watts peak power."

Uvex Jakkyl Hde Convertible Full-Face Helmet - Review
My thoughts are similar. I believe that the technology is all over the map, but I also am in contact with a number of helmet designers, many of whom were skeptical about rotational trauma. All key players have done their own testing in secret and all are on board with a mechanism now. I can't name names, but the entire staff of one maker that was staunchly anti MIPS won't ride without it now. I'll look up that TED episode, thanks.
