Challenge releases Corespun cotton Team Edition tires.

Challenge Tires is an Italian brand that has a rich company history of handmade tubular tires. They sponsor a wide variety of road and cross teams and racers including Richard Sach's Cross Team, Jon Cariveau (Moots), European Champion Helen Wyman and of course, Jonathan Page. Before now, you had to be one of the elite sponsored athletes to ride their Team Edition Corespun cotton tubulars. Well, you can throw that sponsorship application out the window because Challenge has now made the Team Editions available to the public.

The Challenge Tires Team Editions are well known for their supple casings and they are available to all skilled cyclocross racers looking for an extra edge on the competition. After a year of testing on the World Cup circuit and 19 national championship podiums worldwide, the Team Edition cotton Grifo and Limus tubulars have been proven without a doubt in the real world of pro racing. The tires are now available from Challenge distributors and headed to retailers. MSRP is set at $129.00 (per tire).

Here is some rider input from some of the top Challenge racers describing their experience.

"I found that I was able to ride up many things that other riders weren't, due to the incredible traction I got on every surface I tried them on," Page comments on the Team Edition tires, adding that they allow him to run a greater range of pressures than stiffer tires.

Wyman agrees, stating "I've ridden most of the tubulars available on the market, and these are as supple as any others, as well as providing a long-lasting sidewall."

Enjoy improved traction and expanded contact points thanks to the supple casings, which conform so well to the terrain it's like riding on rails. Confidently run low pressures without the fear of folding that coincides with stiff casings, or run higher pressures and still benefit from improved contact and grip over everything in your path.

"Challenge's cotton casing really gave me the opportunity to push my limits with cornering," remarks 2013 U.S. cyclocross nationals silver medalist Jade Wilcoxson. "I was able to run lower pressures and my speed was only limited by my own fear - not the tires - and that's a good problem to have."

Greet slick or sticky mud with smug confidence, knowing the Team Edition Limus is the tire that gives mud nightmares, due to its superior traction and mud-shedding capabilities and let the faithful Team Edition Grifo school the competition on any dry terrain.

Please note that cotton tubulars require additional care, as their casings are more delicate than other materials. Though Challenge Team Edition tires come pre-sealed with a light layer of latex, it is important to pay careful attention to wear and re-seal as raw fibers begin to show. Also, avoid heavy scrubbing, direct power washing and cleaning with chemicals or solvents as these can damage the cotton casing. Store them lightly inflated and round in a dry, dark, room-temperature place. Challenge recommends avoiding exposing dry-conditions tires to moisture for the best longevity. Proper care of these handmade tires will provide you with many high-performance race days.
