ADDIX rubber compounds make all of our legendary Evolution mountain bike tires better.
The perfect compound for every demand: SPEED, SPEEDGRIP,
SOFT, ULTRA SOFT. The tests in the lab and in the field demonstrate: ADDIX performs better than any other compound before – in all disciplines: XC, AM and TRAIL, ENDURO and DOWNHILL.
ADDIX is immediately recognizable by the label on the sidewall and the colored stripe in the tread.

XC Race
ADDIX SPEED is the compound for XC race specialists. It catapults our XC tires into a new performance dimension.
Here’s the answer for those who’d like to go even faster. There’s only one thing that ADDIX Speed really loves and that’s speed. So the rolling resistance has been chopped yet again.

XC / AM / TRAIL
ADDIX SPEEDGRIP, the universal compound. It definitely has the widest range of use. Perfect for XC, AM and Trail: for the majority of EVO tires there’s a version with ADDIX Speedgrip! It replaces the previous PaceStar compound where a significant, though not the only difference, during extensive use is more mileage and a longer life.
Lots of everything: speed, grip and durability. Combining all three characteristics to achieve the perfect compound is almost impossible in theory, but now we’ve done it with ADDIX Speedgrip to an extent that we never thought possible!

ENDURO / DOWNHILL
ADDIX SOFT is a compound that bridges many disciplines. It’s just as at home in the enduro and downhill world as it is in the demanding discipline of all-mountain and trail riding. It also impresses when used in combination with other ADDIX tires – more speed: Soft on the front, Speedgrip on the back. Or more damping: Ultra Soft on the front, Soft on the back.
Rides superbly and provides impressively good damping. That’s ADDIX Soft. We’ve dug deep in the tire builder’s bag of tricks to create the perfect balance between the two. The result is a compound that’s amazingly good fun and yet is significantly more durable than the previous TrailStar compound. Tip: ADDIX Soft is also ideal for e-MTBs. Here it really plays to its strengths of “great damping and powerful grip”, and due to the optimized low-temperature properties it does this all year round!

ENDURO / DOWNHILL
ADDIX ULTRA SOFT is the ADDIX compound for hardcore use in enduro and downhill. Sensationally good damping has been further improved over the previous VertStar compound, while at the same time ADDIX Ultrasoft is suitable for all-weather use due to significantly improved low-temperature properties when it comes to grip and damping.
Extremely soft to cope with very difficult challenges. ADDIX Ultra Soft appears to stick to the ground, literally clawing its way into the subsoil because there’s only one goal in sight: maximum damping and maximum grip.

Markus, you’ve been involved in all the major turning points at Schwalbe. How do you see ADDIX?
It’s a really big thing. Never before have we taken such an ambitious step with the compound. In actual fact, we’ve left no stone unturned, not with the formula and even less with the processes. We’ve really gone to town on it: new mixer, new team, new goals. And to be fair, we were pretty well set up even before that. It’s just that with ADDIX we’ve clearly got even better, and what I’m particularly pleased about – in precisely those areas where we were seen to have weaknesses. Now we can provide convincing answers, for example about the durability or the low temperature properties of the two soft compounds.
Previously, all the EVO compounds for MTB tires were multiple compounds. Is that going to continue?
Whether we’re using a mono or multiple compound in a tire will be one of our trade secrets. With ADDIX, mono/dual/triple is one tool among many but it’s no longer in the foreground as it was a few years ago. What we’ve achieved with ADDIX, to an extent never seen before – depending on the compound’s properties – the tire’s performance remains stable over its lifetime. And tires with ADDIX have a longer lifetime! That’s what counts.
All the legendary EVO tires are now available with the new ADDIX. As a tread designer, these are all your offspring. Does the new compound really make such a huge difference?
Yes. Of course, the wow effect is not going to be the same for all of them. With one you’ll experience the difference more in longer distances and with another more in extreme conditions. There are four very different compounds and tires for very varied discipline. But if the tires are all my offspring, then all I can say is that I’ve always been really proud of them and I’d never have believed that they would be capable of such a career move.
