Continental Terra Hardpack TR 50 road bike tire on a rolling resistance test machine

The Continental Terra Hardpack is a tubeless-ready, semi-slick gravel bike tire that's available at quite a good price when we compare it to most other high-end gravel bike tires that we've tested over the past 2 years. For now, it's only available in the 50-622 size, but given its performance and price, we hope to see some smaller sizes shortly as well.


To keep the price down, the Terra Hardpack comes with Continental's PureGrip compound instead of the premium BlackChili compound they use on their most high-end tires. Even though this seems like a downgrade, we've already tested some other tires that come with the PureGrip compound, and it performs very strongly in our wet grip tests. It does roll a bit slower, and if you're looking for pure rolling performance, the BlackChili compound is the better choice.


Together with the Terra Hardpack review, we're also introducing a new protocol for the inner tubes we use during the tests. As you might know, tubeless-ready gravel bike tires were still tested with an inner tube as we stuck with our original inner tube protocol that we introduced in 2014. As tubeless tires are now the norm for most high-performance tires, we have to move with the times, which is why we now test all tubeless, tubeless-ready, and tubeless-compatible tires tubeless with sealant.


This change affects the test results of 117 out of 266 tires we tested between 2014 and 2022. To keep the data "compatible" and easy to compare, the rolling resistance of those 117 tires has been recalculated with data we obtained from inner tube tests. The original test data is also still available, and you can find it on the tire's review page, where you now see 2 sets of rolling resistance data.


We also changed our test wheel as our previous wheel wasn't tubeless-ready, and inflating some tubeless-ready tires without an inner tube was troublesome. We used a rim with the same width, and the width and height measurements come out the same for both the old and new rims.


You also might have noticed from the picture above that we moved our test lab to a new location where we have more room to expand. We also took apart the rolling resistance machine for servicing and gave it a big makeover. We're now ready to keep on testing tires for years to come.

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.

The Continental Terra Hardpack performs well in our tests, with a strong performance in the (center) wet grip test, which again shows us the Continental PureGrip compound is one of the best gripping compounds. It isn't the fastest rolling, our most puncture-resistant tire, but when we also consider its price, we're sure this will be quite a popular choice.


We did notice the tread is relatively narrow on this tire, but given its tread pattern, we're not sure how this will affect its real-world rideability. The semi-slick tires with a slick center and knobs along the edge of the tire are always a tradeoff when it comes to lean angle, as you'll want to be on the edge of the tread at some point. When the tread is too wide, you might never reach the knobby part of the tread.


RATING: 4.5 / 5
TEST VERDICT:
Highly Recommended
