Understanding your tyre compounds

First things first - there is no one tyre to conquer them all. Now, with that out the way let’s very broadly paraphrase the original science: Improving grip and rolling resistance, durability and damping are the typical conflicting aims of tyre technology. Enhancement of one comes at the expense of another.


Okay, so a single compound can never be the answer to everything, ultimately then it’s all about making intelligent compromises aimed at edging that little bit closer to perfection.

In Schwalbe’s strive to develop a completely new generation of rubber compounds then, they went deep. Super deep: 30 employees led by head developer Markus Hachmeyer and compounder Wolfgang Arenz have been working on the new formulas and processes since 2015.

The result: Addix

The Addix compounds offer a new level of quality in terms of all parameters. Markus Hachmeyer explains, “with ADDIX we’re achieving a whole new level of performance and quality.
Never before have we taken such an ambitious step with the compound. It’s obvious that with ADDIX we’ve become even better. To mention but two striking advances: in terms of durability, our tyres have become much more impressive across the board, and the low-temperature properties are now excellent, and not only in the soft compounds”

That is all good an well, but what is the tyre for you:

Schwalbe has created four Addix compounds to meet the specific requirements of cross country, all mountain, trail, enduro and downhill:

Addix Speed: for XC racing. There’s only one thing that Addix Speed really loves and that’s speed. So the rolling resistance has been significantly reduced yet again. It’s lower than with the previous PaceStar, but at the same time Addix Speed is more durable and more resilient.

Addix Speedgrip: the universal com- pound for Cross Country, All Mountain and Trail. Resulting in a version with Addix Speedgrip, for almost all Evo tires. Durability is 62 percent higher compared to its predecessor PaceStar, with grip up by 35 percent.

Addix Soft: orange identifier: a compound for Enduro and Downhill as well as for challenging all mountain and trail riding. It also impresses when used in combination with other Addix tires – more speed: Soft on the front, Speed- grip on the rear. Or more damping:

Ultra Soft: purple identifier, on the front, Soft on the rear. It’s significantly more durable than the previous TrailStar compound.

Now, to take it to the next level of choice (and not to confuse you), let’s look at the different quality lines in the Addix compound:
Active line – offers reliable brand quality at entry level
Performance line – Excellent quality for intensive use. The best value for money tyres and now available as tubeless ready
EVO (Evolution line) – The very best possible tires created with the highest grade materials using the latest technologies.
