Handmade TLR (H-TLR)
New Handmade TLR (H-TLR) perform better than any vulcanized tubeless system! Challenge Handmade TLR are made from the same materials and processes as our handmade tubulars but instead of sewing an inner tube inside the casing is wrapped around a aramid bead to form a tire that fits on a tubeless rim.
The HTLR is molded flat, not in a horseshoe like a vulcanized tyre. This shape allows the casing to naturally deform over surface imperfections and minimize rolling resistance. A normal vulcanized tubeless tire is molded in a U-shape to make the sidewalls rigid so the system does not “burp” or lose air when it deforms after it encounters a surface imperfection. The new Challenge H-TLR is anything but normal. Where vulvanized is stiff, high rolling resistance and uncomfortable to ride, the new H-TLR maintains the soft supple qualities of all Challenge Handmade tires but sets up with a sealant on TLR wheels.
A bead-to-bead inner coating gives added puncture protection to these new H-TLR tires and greatly reduces any air pressure dissipation. Enhanced longevity has been gained with the addition of an aramid bead protection strip, to reduce rim chafing.
The unique Challenge Handmade Tubeless system is the closest thing to a high performance Handmade Tubular that you can fit on a tubeless Ready clinchers."
