Together with the Terra Speed TR, Continental also launched the Terra Trail TR which is a more aggressive gravel bike tire made for more challenging conditions. On paper, the only difference between these tires seems to be the tread pattern but our tests show these tires are more different than you might think.

What is also different is that the Terra Trail is only available in the 40mm wide sizes 40-622 and 40-584 while the Terra Speed (read our review) is available in both 35mm and 40mm wide versions. This once again indicates that the Terra Trail is intended for somewhat heavier conditions where grip is more important than absolute speed.


As we mentioned earlier, the specifications of both tires are almost the same and both tires use the well-known Continental off-road recipe: 3x180 TPI tubeless-ready casing, reinforced "Protection" sidewalls, and their "Black Chili" compound.

The CX/Gravel section is a multi tire size section, air pressures have been adjusted to the measured casing width.

All numbers are for a single tire at a speed of 29 km/h / 18 mph and a load of 42.5 kg / 94 lbs.

Use the formula: RR (Watts) = CRR * speed (m/s) * load (N) to calculate rolling resistance at a given speed and load.

Conclusion


  • Continental Terra Trail TR
Performance compared to all other CX/Gravel tires
(100% is fastest - lightest - highest - strongest)

Our results show that the Terra Trail has a considerably higher rolling resistance than the fast Terra Speed (compare side by side here). The difference is so big that this can't be explained by the 0.2 mm higher knobs in the middle of the tire since the rest of the tire construction is the same. We've also seen these same differences in the test results between the Race King and Cross King mountain bike tires.


We are therefore once again convinced that although Continental specifies both the Terra Speed and Terra Trail use the "Black Chili" compound, these are not exactly the same compounds. We assume that the "Black Chili" compound as applied to the Terra Trail gives more grip but rolls slower than the version used by the Terra Speed.


We're disappointed Continental doesn't specify which exact compound is used because this would make it much easier to make an informed decision when choosing a tire. We expect Continental to use 3 or 4 versions of the "Black Chili" compound internally, all of which have different characteristics.


All in all, the Terra Trail is certainly not a bad tire. Look for yourself on the CX/Gravel overview page to see the differences between the other tires that we've tested to date.
