Leave it to the tech-crazed engineers at Mavic to come up with not only rear- and front-specific tires, but tires that are also designed to work optimally in conjunction with a wheelset. The Crossmax Roam XL Tire lives behind the Crossmax Charge, and both are designed to call the Crossmax Enduro WTS Wheelset home.
When compared with the front-specific Charge tire, the rear-specific Roam is a touch less tacky but more durable and with a higher rolling efficiency. It's a dual compound tire with a durometer rating of 50a on the shoulders to enhance grip in corners and a strip of 60a in the center for low rolling resistance. The Roam's blend of traction, rolling resistance, and tread longevity recommends it for aggressive, fast riding that holds corners and lays down power.
Like its front brother, the Roam also incorporates Guard 2, which uses a dual-ply, 66 TPI casing to help prevent flats, even at the low pressures you'll be able to run because of the UST Tubeless Ready design. Rolling tubeless means you can ditch the heavy tubes and rock a lower PSI, which makes for better handling and grip at lower rotational weight.
The tire's tread graduates from short, ramped studs in the middle for aggressive power transfer and longevity to pronounced knobs on the shoulders in the softer compound for confident, don't-have-to-slow-down cornering. The 2.2 casing further complements the tire's aggressive disposition.
The Crossmax Roam XL 27.5 Tire is rear-specific and comes with yellow branding.
