“The very first A-Class Kevlar tire production sold out immediately upon arrival.”
Aresbikes team rider York Uno put this popular high-pressure tire to the test. Here’s what he thought of them:

“Like the regular A-class tires, the Kevlar version comes in two sizes, 1.90 and 1.75. For speed and agility, I went for the thin, lightweight 1.75 tires, because they’re easy to handle, and good for tire-grabbing tricks.
The biggest difference between the regular A-Class and the Kevlar version is the weight. While the regular A-class 1.75 is 410g, the Kevlar A-Class 1.75 is a very light 345g. This lightness really allows better bike control.
These high-pressure tires have been developed to run from a regular 110psi (7.5 bar) right up to 180psi (12.4 bar).
The Kevlar tire allows you to feel the true value of Japanese-made high-pressure tires.
The compound is the same as my current A-class tires, so I did my first test ride at the same pressure to have a better comparison. Right from the very start I was amazed at how well they gripped.
From the beginning, compared to the regular A-Class tire, the Kevlar version required a smaller amount of wax during the manufacturing process. Wax is used to get the tire out of the manufacturing mould, and to prevent deterioration during this process.

I tested the tires on asphalt, concrete, wood, marble floors…and quickly adapted to riding with the Kevlar tires.
The ability to easily adjust the tire pressure allows for an amazing grip and a really smooth ride on every surface! It’s the kind of feeling I couldn’t imagine from any other all-round flatland tire I’ve tried before.
And because they fold up so small, they’re really convenient to carry around. They’re ideal to keep in your bag as spares for contests or filming.
Make sure you pick up some A-CLASS 1.75 Kevlar Tires!”
