Challenge Grifo Cross Tubular Tire $114.95
One of the best improvements you can make to your cross rig.
If you ride clinchers in cross races, chances are, that at some point, you've kicked yourself for not upgrading to a setup that incorporates the Challenge Grifo Cross Tubular Tire. It might have been when you flatted with one lap to go , or it could have been when your arch-rival edged you out in a slop'fest because they had a clear traction advantage. Of course, going tubeless could prevent these situations too, but the fact remains that the combination of a tubular tire's light weight and low PSI requirement make it a clear favorite for cross. And when it comes to all-around tubular cross tires, we'd argue that none perform like the Grifo Cross.
The hand-made Grifo Cross has a highly puncture-resistant and lightweight Super Poly casing. With 300 threads per inch, you can expect a remarkably supple ride--and it's a difference that you'll feel the first time out. Additionally, the Grifo tread is hand-glued onto the casing when the casing is already mounted and inflated on a wheel. As a result, the tread isn't put under tension when you inflate the tire on your wheel, and that lack of tension leads to lower rolling resistance, added grip, and increased comfort.
A superior all-around cross tire must have tread that provides a harmonious balance between low rolling resistance and grip, and the Grifo's tread is world-renowned for striking that balance perfectly. The knobs are relatively low-profile, but they're effectively spaced to shed mud and provide excellent traction. Simply put, the Grifo Cross rolls fast, bites into soft ground, and corners as if it's on rails.
The Challenge Grifo Cross Tubular Tire is available in a 700c x 33mm size and in the color Black/brown. Each tire weighs in around 415 grams. Please note that Challenge gave this tire a latex inner tube to save as much weight and roll as fast as possible. Because latex is more porous than butyl rubber, you'll have to pump up a bit before your rides.
What community has to say
Best all around CX tire
- Familiarity: I've put it through the wringer
I've used these tires for the past two years and wouldn't change a thing. They hook up in all conditions and roll really fast.
- Familiarity: I've used it once or twice and have initial impressions
I just got these installed...they are only the second cross tubulars I've owned.
They seem to corner well and all that.
What I really have to say is that the latex inner tube mentioned in the post...It definitely loses air! Brand new, it leaks as bad as road tubulars that I've put literally a thousand miles on.
