Would this tire be well suited for some of the chunkier long distance gravel events such as Rebecca’s Private Idaho and Big Sugar in Arkansas? Next, we wanted to determine puncture resistance. Besides testing in sunny weather, we also braved the occasional late summer rains. JRA with the Angry Asian: Should we be considering full-face road helmets? Now on with the riding. Tyre construction varies from manufacturer to manufacturer and of course from model to model. It is better than the Venture, in my opinion, and I intend to find out if it is close to a Riddler. 700 x 35C) indicates the approximate outer diameter (700 mm) and tire width (35 mm). Its qualities were able to convince all of our testers. The centre tread consists of small, tightly packed knobs for speed . The tire should be hard enough that it doesn’t squirm on compact surfaces. The original Nano40 (black wall version) runs a true 40mm wide, has an unusual “tall” casing profile for a lot of volume, and has that traction with semi-low rolling resistance that a lot of folks loved about that tire. First of all, I need to do a little house cleaning. With all of gravel riding’s intricacies, it is particularly important to have firm and safe contact with the ground. In the pursuit of clarity, ETRTO (European Tyre and Rim Technical Organization) introduced the European tire and rim standard.

I have also heard that folks are having some issues with Nano40 tires, but that is all I know. Another option is the 37 or 45mm WTB Riddler, but we think its tread is more hardpack-specific. To make the group test as accurate and fair as possible, we limited our test field to 700c tires with widths ranging from 37 mm to 43 mm. We asked ourselves how the cycling industry will respond to the diverse requirements of “gravel” if it isn’t even able to properly define the term. How much feedback do they give from the surface we’re riding on? In terms of width, I had noted that the 44mm version was a tad bit undersized right after mounting, but I was sure that these would stretch out to a full 44mm width, and I was correct there. My primary goal was low rolling resistance for Adventure […], […] What’s the best gravel tire? Thankfully, the current Riddler will carry on unchanged (it earned a spot as one of James Huang’s most loved products of 2019) for those wanting a faster semi-slick, but if you’re one to regularly get a little more, well, rad on your gravel bike, the Raddler looks like it might be a solid choice. For example, the ETRTO size classification “37-622” indicates the width (37 mm) and the inner diameter (622 mm) of the tire. The downside of it is that with increased choice comes increased confusion and indecision. As already mentioned, our aim in this group test was to identify the best all-round gravel tire.

The Resolute rolls better, but only slightly so, in my opinion. They damp impacts well, and the rubber compound works just fine. Therefore our suggestion is: even if the tire manufacturer recommends at least 3.4 bar – start by inflating the tire with only 2.5 bar and see how that feels. We will get a back to back roll down test to determine a winner for the wrap-up on this review. Attention: if you like riding up curbs, you should make sure that you have enough pressure in your tires to prevent damaging your precious rims.

The 45mm Riddler is generous 118mm bead-to-bead and weighs more at 540g. I found bite in muddier corners, and on some well packed snow also. To determine the rolling resistance on compact surfaces, we mounted the tires on the same rim with the same pressure and tested them at 20 km/h on the test bench, one after the other. These lab values are a good indicator for tire performance in a controlled environment, but since we’re “realists”, we placed more emphasis on the results of the practical test in our final evaluation – keep it real! Other important criteria were the damping and the comfort the tires provide. Gravel: seemingly omnipresent, and interpreted in many different ways. So Far….. Sure, it did fling a stone here or there, but I was pleasantly surprised that this tread pattern seemed to behave itself and not fling a lot of smaller stones around. A pressure loss of 1 bar per month is considered normal. They are essentially similar tires- one aggressive, one not so much- so the naming convention follows suit.

The inch classification (e.g. I did note that despite the closely spaced tread blocks in the center of the tire that the Raddler did not “fling” gravel bits like some other tires are noted for doing. Rolling resistance and cornering (especially pavement) are areas I’d be most interested. There are gravel tires that perform better on hard-packed surfaces, and others that are true trail kings. This means that the tire volume can vary depending on the model, even if the size classification is the same.
