What Our Gearhead(R) Experts Are Saying:"The Limus Pro Tubeless Tire is the tire I reach for when the course turns to soup. The deep, well-spaced knobs shed mud instantly and hook into corners that would wash out lesser rubber without hesitation. The handmade Super Polyester casing adds a suppleness underfoot that machine-made tires just cannot replicate at speed."Mud-soaked courses separate confident racers from cautious ones, and the Challenge Limus Pro Tubeless Tire is the tire that tips that balance. Named for the Latin word for mud, it was built for exactly the conditions that make riders second-guess their equipment. Deep, aggressive knobs spaced wide enough to self-clean through the sloppiest corners keep forward momentum going where other tires pack up and lose traction. Off-camber sections, steep punchy climbs, and that one sketchy corner everyone walks? The Limus Pro Tubeless Tire was designed for all of it. What sets this tire apart from any mass-produced competition tire is the construction itself. Challenge's handmade process layers natural glues and latex coatings onto a 300 TPI Super Polyester casing, producing a tire that conforms to the terrain instead of fighting it. The SMART compound beneath the tread stays soft and grippy because it never goes through the heat and pressure of vulcanization. Add Puncture Protection System fabric between tread and casing, and you get a race-day tire that handles the full brutality of a muddy cyclocross circuit without costing you confidence or momentum.
