New WTB Marco XC Tire – Race-Ready Speed for Cross-Country Trails

WTB has done it again. Their newest release, the Marco XC tire, brings race-tuned speed and traction to riders who demand maximum performance with minimum weight. Built from the ground up for cross-country racing and fast trail riding, the WTB Marco XC is designed to accelerate quicker, corner harder, and climb faster, all without weighing you down.

Whether you're chasing podiums or just hunting KOMs on your local trails, the Marco delivers the kind of performance edge that turns effort into efficiency.

What Makes the Marco XC Special?

The WTB Marco XC isn’t just another fast-rolling tire, it's been tested under elite-level pressure and fine-tuned for the demands of modern XC racing. While it shares a similar center tread profile with WTB’s popular Ranger, the Marco takes a sharper turn toward pure performance, making it ideal for riders looking to squeeze every last second out of their ride.

Lightweight XC Construction

Clocking in at just 715 grams for the 29 x 2.4” version, the Marco is one of WTB’s lightest mountain bike tires. That means quicker acceleration, easier climbing, and less fatigue over long race days. If you've been running heavier all-mountain tires on your XC rig, this switch will feel like shedding a backpack.

Fast-Rolling Center Tread

The closely spaced center knobs are optimized for low rolling resistance<, helping you maintain speed on flat terrain while conserving energy for the climbs. The tread pattern is perfect for dry, dusty, and hardpack trail conditions, giving you a fast, predictable ride on everything from local loops to national race courses.

Confident Cornering with Reinforced Side Knobs

Unlike some other ultra-light XC tires, the Marco doesn’t sacrifice control. The taller, widely spaced side knobs give you extra grip in the corners and allow you to carry more speed through technical switchbacks and loose-over-hard terrain.

Built for Dry, Hardpack Cross-Country Trails

The Marco XC is a specialist and that’s a good thing. It’s made specifically for dry, hardpack terrain, making it a top choice for Southern California riders, summer XC races, or anyone looking for that fast and firm trail feel.

If you ride in areas with frequent rain, mud, or loamy singletrack, you might want to consider a mixed-condition tire. But if you’re racing or riding in predictable summer conditions, the Marco XC gives you the perfect balance of speed and bite.

Tubeless-Ready with WTB’s Proven TCS System

Like many of WTB’s top-tier tires, the Marco features TCS (Tubeless Compatible System) technology, which means easier setup, fewer flats, and the ability to run lower pressure for increased traction and a smoother ride. Pair it with your favorite sealant and rim tape, and you’re ready to roll tubeless on race day.
