Baby Limus Pro Tubular Tire

What Our Gearhead® Experts Are Saying:

"The Baby Limus Pro Tubular Tire is what I recommend to any racer who wants the full tubular experience without stepping into the premium silk or cotton casing tier. The 300TPI Super Polyester casing with a latex tube gives you a ride quality and cornering feel that is genuinely superior to any clincher option at this price point, and the Smart compound paired with PPS protection makes it a tire you can race aggressively and trust through a full season of hard courses."

The tubular format exists for a reason, and the Challenge Baby Limus Pro Tubular Tire makes that case more convincingly than almost anything else at its price point. The pairing of a 300TPI Super Polyester casing with an integrated latex inner tube creates a system where every element works together to maximize compliance, traction, and ride feel in a way that clincher and tubeless setups structurally cannot achieve. The latex tube adds a final layer of suppleness to a casing that is already significantly softer and more water-resistant than nylon alternatives, and the combined effect is a tire that drapes over variable CX terrain and maintains contact and feedback through corners that would push a stiffer tire toward the edge of grip.

Challenge's handmade production process is central to what makes this tire perform the way it does. Skilled craftspeople assemble each tire step by step, applying high quality natural glues and latex coatings to the Super Polyester casing in a small-batch environment that allows for a level of quality control impossible at industrial scale. The Smart compound is applied without the heat and pressure of vulcanization, which means it retains its intended softness and grip character throughout the tire's life rather than hardening off the way mass-produced compounds often do. PPS puncture protection adds a tightly-woven fabric layer between the tread and the casing, providing meaningful flat resistance on courses littered with debris, barriers, and sharp course edges without adding stiffness or weight that would compromise the tire's suppleness.

At 430g in 700x33C, the Baby Limus Pro Tubular Tire sits comfortably within the weight range expected of a race-ready handmade tubular, and its all-condition tread pattern makes it a genuine single-tire quiver option for racers who want to show up prepared regardless of what the course and weather deliver. Note that deep-profile rims may require Challenge Presta Valve Extenders for proper tubular mounting.
