Riding your fat bike on ice just got even better with the redesigned Dillinger tread pattern and tubeless compatibility. Dial-in your traction by custom installing up to 240 studs that allow you to rail icy off-camber singletrack with confidence and control, while taller side lugs bring improved cornering in snowy conditions. Dillinger's center tread is tightly spaced for speed when you need it so you can power up an icy climb and rip down the other side as the studs claw into the slick surface.

From loose snow to icy freeze-thaw and everything in between, Wrathchild craves the best and worst winter conditions. Deep center lugs aggressively claw into unconsolidated snow for extreme acceleration and braking traction. Super-tall side lugs dig into loose snow to provide predictable and confident cornering. It doesn't matter whether there's ice on the road ahead, the Wrathchild is available in both studded and non-studded models. Let Wrathchild bring out your inner-child and go carve up some local trails.

Your tires are the only thing connecting you to the road or trail, and having optimal tire pressure can have more impact on ride comfort than both frame and wheel choice combined. But finding the right tire pressure requires trial and error. TyreWiz for Moto is the first-of-its-kind tire pressure sensor for Zipp 3Zero Moto wheels and takes the guesswork out of finding that optimal tire pressure. Lightweight and durable, TyreWiz adds only 10 grams to your tires. With an IPX7 waterproof and dustproof rating, you can confidently ride on any type of trail and know that your tire pressure sensor will keep going strong. TyreWiz reports data with +/-2% accuracy at a resolution of .1 PSI; vastly more accurate than any tire pump on the market. TyreWiz monitors the air pressure in real-time and relays the data to a cycling computer or a smartphone. That information is relayed to the SRAM AXS app and delivers personalized recommendations and pressure alerts. TyreWiz gives riders access to highly accurate, real-time tire pressure data to make decisions that can affect rolling resistance, traction, tire wear, and rider comfort. Features - Data reported with +/- 2% accuracy at .1 PSI resolution. - Only compatible with Zipp 3ZERO Moto wheels. - Inexpensive, user-replaceable CR1632 battery lasts for 300 hours. - IPX7 dustproof/waterproof rating.
