Tire Test - Schwalbe Hans Dampf TrailStar

Schwalbe Hans Dampf TrailStar mountain bike tire on a rolling resistance test machine

The Schwalbe Hans Dampf with TrailStar compound is the first tire I'm testing that makes use of this grippier compound. In the last couple of years, I've tested a lot of Schwalbe mountain bike tires which nearly all used the PaceStar compound. The PaceStar compound is a great compound that combines a low rolling resistance with a decent amount of grip and durability. The TrailStar compound is optimized more towards grip than rolling resistance, but how much speed are you really giving up?

When checking Schwalbe's website, they indicate the Hans Dampf with TrailStar is rated a 3.0 out of 6 on their speed scale. The Hans Dampf with faster PaceStar compound, on the other hand, is rated a 3.5 out of 6 on their speed scale. The half point lower rating on speed seems to indicate there is only a marginal difference between the PaceStar and TrailStar compounds.


After testing both the PaceStar and TrailStar versions of the Hans Dampf, I can tell you that the difference between these compounds is immense. Read on to find out that the difference between these compounds isn't just a half point on a scale of 6.

Size and Weight Measurements


Size and Weight Measurements (Bike Wheel: 622-17C, Pressure: 35 psi / 2.4 bar)
Specified Weight 850 grams
Measured Weight 840 grams
Measured Width Carcass 56 mm
Measured Width Tread 60 mm
Measured Height 55 mm
Measured Knob Height Center 3.8 mm
Measured Knob Height Edge 6.0 mm
Measured Total Thickness Sidewall 0.85 mm
Measured Total Thickness Center (excluding knobs) 1.90 mm

Both the Hans Dampf TrailStar and PaceStar have the same specified weight of 850 grams for the 29 x 2.35 version. My sample comes in slightly below the specified weight at 840 grams. Both tires measure exactly the same: casing: 56 mm, max width (knobs): 60 mm, height: 55 mm.


The tread pattern of both the TrailStar and PaceStar is exactly the same. The center knobs on the TrailStar measure nearly the same at 4.0 mm. The edge knobs have a height of 6.0 mm. The sidewalls have a thickness of 0.85 mm which is spot on to most other Schwalbe mountain bike tires with SnakeSkin sidewalls.


Rolling Resistance Test Results


Rolling Resistance Test Results (Speed: 29 kmh / 18 mph, Load: 42.5 kg)
Inner Tube Conti MTB 29 (225 gr butyl)
Rolling Resistance 55 psi / 3,8 Bar 34.9 Watts
Rolling Resistance 45 psi / 3,1 Bar 36.1 Watts
Rolling Resistance 35 psi / 2,4 Bar 38.5 Watts
Rolling Resistance 25 psi / 1,7 Bar 44.5 Watts
Rolling Resistance Coefficient (Crr) 55 psi / 3,8 Bar 0.01046
Rolling Resistance Coefficient (Crr) 45 psi / 3,1 Bar 0.01082
Rolling Resistance Coefficient (Crr) 35 psi / 2,4 Bar 0.01154
Rolling Resistance Coefficient (Crr) 25 psi / 1,7 Bar 0.01334

Rolling resistance of the Hans Dampf with TrailStar compound is very, very high. At the low air pressure of 25 psi / 1.7 bars, rolling resistance comes in at 44.5 watts which is 17.4 watts more than the Hans Dampf with PaceStar compound (27.1 watts). At the higher air pressure of 55 psi / 3.8 bars, rolling resistance comes in at 34.9 watts which is 13 watts more than the PaceStar version (21.9 watts).


These tests indicate that the difference in rolling resistance between the TrailStar and PaceStar compounds is more than 60%. I'm surprised by this huge difference as the ratings on Schwalbe's website indicate a difference of just a half point on a scale of 6. It would be nice if the ratings on manufacturers websites would get closer to the truth as people are basing their tire choices on these kinds of ratings. A rating of 2 out of 6 would be more honest for the TrailStar version, but I guess that's out of the question for the marketing department.



Puncture Resistance Test Results


Puncture Resistance Test Result (higher is better)
Puncture Resistance Tread 8
Puncture Resistance Sidewall 5

Puncture resistance comes in close to the other tires as well. The sidewall score of just 5 points is a bit on the weak side for a SnakeSkin tire but could be the result of the softer compound.




Conclusion


Schwalbe Hans Dampf TrailStar  mountain bike tire on a rolling resistance test machine

The difference in rolling resistance between the Schwalbe PaceStar and TrailStar compounds is immense. This doesn't have to be a bad thing as you might get a lot of grip in return for the higher rolling resistance. The main problem I have with this tire is the false rating on Schwalbe's website. Schwalbe indicates there is only a half point out of 6 (8%) difference in rolling resistance between the TrailStar and PaceStar versions of this tire while my tests indicate a much bigger difference of 60%.


If you're deciding between the TrailStar and PaceStar compounds, keep in mind these big differences. A PaceStar on the rear and TrailStar on the front might be an ideal combination as the front wheel contributes the least to the total rolling resistance as there is less load on the front wheel.
