Technologies:
Challenge Handmade Clinchers (HCL): These Handmade Clinchers 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 an aramid bead to form a tire that fits on a clincher rim. The HCL is moulded flat, not in a horseshoe like a TLR or VCL. This shape allows the casing to naturally deform over surface imperfections and minimize rolling resistance. A tubeless tire is moulded 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 tubeless tire’s stiff sidewall compromises its ability to equal a supple HCL with a latex inner tube.

About the Challenge brand

In 2003 Challengetech created its own brand “Challenge”. Challenge, as the word says, wants to point out how difficult and exciting it is to keep the tradition of high quality products, created with obstinacy, with the steady research of special materials and through handcrafted processes. Since the 2000s, Challengetech has being producing tubulars for other brands, thanks to the constant use of these products in the professional cycling.
