- Maxxis Aspen EXO TR
The Maxxis Aspen is a mountain bike tire with a high volume casing and a low profile tread. The Aspen looks like one of the fastest tires from Maxxis as the tread pattern in the center of the tire is quite low and open. The edge knobs are a bit bigger and look like they will provide decent grip when leaned over far enough.

This is a test of the 29x2.25 120 TPI EXO TR version of the Aspen that has a specified weight of 645 grams. The EXO TL part means this version has reinforced sidewalls (EXO) and is tubeless-ready (TL). The compound is a dual compound that is simply called "Dual Compound". We couldn't find much information about this compound so we're curious how it compares to the Maxxis 3C MaxxSpeed compound that we've tested before (Ikon 3C MaxxSpeed and Ardent Race 3C MaxxSpeed).
We've tested a few Maxxis MTB tires in the past and in general, they're not the fastest rolling tires out there. We're giving them another try to see how they stack up to other recent tires like the new 2019 Schwalbe Racing Ralph (read review) and Racing Ray (read review) with Addix Speed and SpeedGrip compounds.

Conclusion
- Maxxis Aspen EXO TR
(100% is fastest - lightest - highest - strongest)
Rolling resistance of the Maxxis Aspen EXO TR with the Maxxis Dual Compound is decent although it's still a bit slower than equivalent tires from Schwalbe. It looks like rolling resistance of the Maxxis Dual Compound is better than that of the Maxxis 3C MaxxSpeed compound which doesn't make sense to us.
The Aspen also comes with lower knobs on both the center and edge of the tread and weight is slightly higher as well when compared to the equivalent Schwalbe tire with reinforced sidewalls.
We rate the Maxxis Aspen 3 out of 5 because its performance is just a bit worse when compared to Schwalbe tires that scored 4 out of 5. Although we rate the Maxxis Aspen 3 out of 5 we still recommend this tire because the differences are small and other factors that we do not test might be more important to you.
